1. General Information
1.1 Overview
AFES is a comprehensive one-stop solution for all your foundation engineering and design needs. Due to AFES’ capability to make reports, construction drawing including bar schedule, BOM and generation of 3D CAD(PDS/PDMS) foundation modeling data, it is very powerful solutions for the analysis and design of all kinds of foundation.
1.2 Background Foundation design is usually done manually thus entailing large storage manpower needs, which is uneconomical and in turn leads to difficulties in meeting quality requirements and deadlines.
The shortness of work period for project, frequent design changes of upstream parts, difficulties in assuming the size of foundations for site and the need to check interference between foundation, underground piping, and electrical cable trench, and coordination with other teams are some of the difficulties encountered during the design stage of a project.
With the absence of a one-stop commercial solution that can solve the above mentioned problems, AFES is the system that can produce all type of foundation analysis and design needed for the construction of foundations, quickly and economically.
1.3 Application Area Energy, Petrochemical, Refinery, Gas, Water Supply, Treatment and Recycling Plants Residential, Commercial Buildings

1.7 Basis of Foundation Design
The following assumptions from the basis of foundation design procedures used by AFES. - The program designs a spread and pile supported foundation. - All piers and footings are assumed to be rigid with respect to load, soil bearing and pile load distribution purposes. - All loads at the top of pier are assumed to act the center of the pier. - Factored soil bearing pressure required for obtaining bending moment in the foundation is determined based on uni-axial in each strip separately. - To determine the shears and bending moments in the foundation, the foundation is divided into many strips and the values are calculated at critical and maximum conditions.

1.9 AFES Program Theory
AFES program has the facility to obtain results of the Conventional and Finite Element Method(=FEM) for foundation analysis and design. The user may use one of the two design methods stated above.
1) Conventional Rigid Method The purpose of a footing is to transfer safely to the ground the dead load of the superstructure (=weight), and all other external forces acting upon it. The type of foundation is also influenced, though to a lesser degree, by the geographical location and climatic of the site, frozen depth, etc.
AFES performs a complete structural analysis and design of foundations as following below. The program uses the following criteria. AFES use two types of load combinations ; Service(=Unfactored Load) and Design(=Factored Load). Service load combinations are used to calculate the soil and pile capacity, overturning moment, and sliding forces for comparison with allowable soil and pile capacity defined in the Setting of Constant window. Design load combinations are used to design the footing and pedestal for flexural and shear as per chosen building code.
1) Conventional Rigid Method a) Soil Bearing Pressure (Shallow Foundation) b) Pile Capacity (Deep Foundation) c) Overturning Moment (Shallow Foundation) d) Sliding Force (Shallow Foundation) e) Shear and Flexural Design (no shear reinforcing assumed) f) Two way Shear Design g) Design of Piers
a) Soil Bearing Pressure (Shallow Foundation) AFES calculates the soil bearing pressure for all service load (=unfactored load) combinations from the allowable soil pressure evaluated by principles of soil mechanics. Any eccentricities, additional bending moments and/or horizontal shears shall be considered in the evaluation of the maximum edge pressures. Soil pressure under the footing is assumed to be linear. For eccentrically loaded footings, the soil pressure may become tension under the part of the footing. In such cases the program set pressure values in uplift zones to zero and calculates new values for the revised equilibrium condition due to “Hand Book of Concrete Engineering” edited by Mark Fintel. The maximum soil pressure should not exceed the allowable bearing defined in the Setting of Constant criteria window. AFES supports biaxial and uniaxial soil bearing pressure analysis. 20 of 272
Qa >= ΣV_appl / Af ± ΣMx / Zx for Uniaxial Qa >= ΣV_appl / Af ± ΣMy / Zy for Uniaxial Qa >= ΣV_appl / Af ± ΣMx / Zx ± ΣMy / Zy for Biaxial
Where, Zx = 1/6 x Lx x Ly2, Zy = 1/6 x Ly x Lx2 : Section Modulus, Af : Footing Area
b) Pile Capacity (Deep Foundation) The user provides the following pile parameters such as representative pile name, type of pile, diameter, length, thickness, elastic modulus, area, allowable Vertical/Lateral/ Uplift pile capacity. Based on these parameters, program calculates the maximum pile capacity. The maximum pile capacity should not exceed the allowable pile capacity. AFES supports biaxial and uniaxial pile bearing capacity analysis.
Ha_pile > = ΣH(i)x_appl / N_pile for Uniaxial Ha_pile > = ΣH(i)y_appl / N_pile for Uniaxial Ha_pile > = √(ΣH(i)x_appl2 + ΣH(i)y_appl2) / N_pile for Biaxial Va_pile > = ΣV_appl / N_pile + ΣMx_appl x Y(i)/ ∑Xi2 for Uniaxial Va_pile > = ΣV_appl / N_pile + ΣMy_appl x X(i)_x / ∑Yi2 for Uniaxial Va_pile > = ΣV_appl / N_pile + ΣMx_appl x Y(i) / ∑Xi2 + ΣMy_appl x X(i) / ∑Yi2 for Biaxial
Where, Ha_pile : Allowable horizontal pile capacity, Va_pile : Allowable vertical pile capacity ΣH(i)x_appl, ΣH(i)y_appl : Total horizontal load, ΣV_appl : Total vertical load N : Total number of piles ΣMx_appl, ΣMy_appl : Applied bending moment about X and Y axis X(i), Y(i) : Distance from X and Y axis to the farthest pile ∑Xi2 ,∑Yi2 : Pile group moment of inertia about X and Y axis
c) Overturning Moment. Overturning moments are those applied moments and shears that seek to cause the footing to become unstable and turn over. Resisting moments are those moments that resist overturning and seek to stabilize the footing. The overturning moment safety factor is the sum of resisting moments divided by the sum of overturning moments. Safety factors defined in the Setting of Constant criteria window. The Resisting moment is overturning moment from the vertical forces such as applied loads, self weight and soil weight and overturning moment resulting from the external applied shears and moments and the summation of all these forces becomes the overall overturning moment at the edge of footing. The overturning 21 of 272
moment safety factor is calculated as the resisting moment divided by overturning moment. Calculation of overturning moment is evaluated about all edges of the footing in the service (=unfactored) load combinations for both X and Y directions.
d) Sliding Force Considering ΣV and ΣH at the bottom of footing, it is obvious that ΣH will cause a tendency for the foundation to slide at the bottom of footing, which is prevented by the friction that is mobilized, the maximum value of which is ΣV(=summation of vertical forces) multiplied by the coefficient of friction between the footing and the soil below. The sliding factor of safety (=FS) against can be stated as follows; FS = ΣV x µ / ΣH. The maximum value of FS normally specified is 1.5. For coarse-grained soils free from silt, µ may be taken as 0.55, while for coarse-grained soils with silt the same may be taken as 0.45. For pure silt the value goes down to 0.35. Calculation of sliding forces is evaluated at the bottom of footing in the service (=unfactored) load combinations for both X and Y directions. For additional sliding resistance you may enter and select the passive resistance of the soil, also applies this value in the both directions.
e) Shear and Flexural Design (no shear reinforcing assumed) Self weight of concrete and overburden of soil normally do not include flexural and shear in the footing because the footing is continuously supported by the soil beneath it. A buried footing resting on a continuous soil bed. Typically it is not included in the design load combinations but the self weight and overburden of soil automatically included in the service load combinations.
The design codes available in AFES are as follows: - ACI318, Building Code Requirements for Reinforced Concrete (USA) - BS 8110 (1997), British Standard for Reinforced Concrete Design (England) - IS 456 (2000), Plain and Reinforced Concrete-Code of Practice (Indian) - KCI-USD99, Korean Concrete Institute of Concrete Design (Korea) -KCI-USD2000 (SI Units) , Korean Concrete Institute of Concrete Design (Korea)
f) Flexural Design In the footing design, the reinforcement required for a footing is computed based on the resulting bending moments at the bottom of footing. In addition, selected reinforcing bars and spacing are computed for the required reinforcing steel area based on the ranges of rebar sizes and spacing specified by the user. The flexural design of footing calculates the maximum moment and required steel for each
22 of 272
strip and for each design load combination. To select the required flexural reinforcing steel of the footing, AFES considers moments at the face of the pedestal on all four sides. The minimum reinforcing ratio calculates the design code for shrinkage and temperature reinforcement. Strength reduction factor can be entered in the Setting of Constant window.
Proportioning the pile cap involves satisfying the one way shear and bending moment requirements at the applicable critical sections in accordance with building concrete design code.
g) Shear Design One way shear (=Beam Action) in accordance with design code at distance of d or d/2 from the face of pedestal in both directions. The d is the distance from the top of the footing to the centerline of the reinforcing steel. The d distance value calculates as follows; Footing thickness – the rebar cover – half the main bar diameter of the footing. The critical plane is assumed to extend over the entire width or entire width per length of the footing. AFES checks shear assuming only the concrete to resists the applied shear; the contribution of the reinforcing steel to shear resistance is ignored.
h) Two Way Shear Design Critical section for two way shear is perimeter (=bo), a distance d/2 or d from around the supported member in accordance with design code.
i) Design of Piers
AFES can design the shear and reinforcement for the piers. For shear design in either direction, AFES presents the required vertical and tie bar and spacing. Also given are the concrete and steel contributions to resisting shear. The total factored load value is listed. For flexure, AFES uses a rectangular stress block, and considers slenderness effects. AFES presents the required vertical reinforcement assuming an equal distribution of bars. AFES does not account for the development length required and the provided development length for reinforcing if it is not hooked or bent into the footing.
2) Finite Element Method (FEM) The AFES analysis is based on the hybrid finite element method with the thin plate modeling as footing. Footings are automatically discretized into well formed quadrilateral and triangular elements at a specified mesh size. Beams are automatically discretized. Soil response is achieved by employing nonlinear spring (=compressing only) supports to model subgrade reactions. Pile reactions, if present are proportional to linear displacements of the supported node and include both compression and tension. 23 of 272
Also program calculates internal forces and deflections for all slabs and beams elements of the foundation. This information is used in the design stage of the program.
The following is a list of the items included in the element stress output; SQX, SQY : Shear stresses (Force / Unit length / Thickness) MX, My : Bending moment per unit width (Moment / Unit length) The element outputs are available at the center point of the element or all corner nodes of the element. All element stress outputs are in the local coordinate system.

g) Allowable Increase of Soil 1) Function Soil subjected to short-term loads like wind and seismic can be increased in vertical capacity by certain degrees. In consideration of this increase of soil bearing pressure, allowable increase soil factor can be taken on the “Allowable Increase Factor of Soil menu. The factors usually can be out by geotechnical studies and may be considered in the perspective of wind, earthquake and test load. To apply the increased factors for design, they need to be set up in the dialog of load combination that will be described later.

Note: As for short-term external force, allowable increase factor is prohibited as long as reduction factors are already considered. Ex) 0.75 x (1.4DL + 1.7LL + 1.7WL)
Typically accepted increase factors are as follows: • LIBYA Foundation subject to stresses produced by a combination of wind or earthquake loads with dead, live, impact and vibration loads shall be proportioned for stresses 33% greater than basic allowable stresses specified by the ACI code. Allowable unit stresses for the design of foundations supporting process equipment may be 20% during the hydrostatic testing of equipment, under static test load.
53 of 272
• TEXAS ABB The allowable unit stress may be increased by 20%. Do not included earthquake combined with test loads. Use 25%of wind load combined with test load.
h) Allowable Increase of Pile 1) Function As described in the previous chapter, increase factors of soil are explained an applied in design of soil foundations. Likewise, pile foundations can have factors increased. These factors are related to horizontal, vertical and uplift capacity. The factors typically give by geotechnical studies and may be considered in the wind, earthquake and test load. To apply the increased factors for design, they need to be set up in the section of Load Combination that will be described later.

Supports of Soil and Pile Foundation
58 of 272
Click “Soil Support” to get the modulus. Enter or check appropriate values in the field displayed: Allowable Soil Stress (qa), Long term, short term. Then click the “OK” button.
Note: See Joseph E. Bowels: Foundation Analysis and Design Page 503. The ks from allowable bearing capacity furnished by the geotechnical consultant as follows;
Fps : ks = 12 x SF x qa
kip/ft3
SI : ks = 40 x SF x qa
kN/m3
Where
SF=3.0(Long Term), 2.0(Short Term)
Qa= Allowable Bearing Capacity of Soil. This equation is based on qa= qult/SF and ultimate soil pressure is at a settlement ∆H=0.0254m or 1 in.(1/12ft) and ks is qult/∆H. For ∆H =6,12,20mm,etc., the factor 40(ot12) can be adjusted to 160(or48), 83(or 24), 50(or 16), etc.; 40 is reasonably conservative but smaller assumed displacements can always be used.

16. Load Case/Combination
16. 1 Main Functions The Load Case/Combination command is used to define, add, edit or delete load cases and combinations.
Assigned load cases can be combined with factors in accordance with a few design methods and specifications. Mainly applied load combinations are Allowable Strength Load Combination and Ultimate Load Combination. Combinations by Allowable Strength Design are normally applied with 1.0 factored value. The purpose of the combinations is to take into account soil bearing capacity, sliding, overturning, uplift check, and pile capacity check for a pile supported foundation. Combinations referring to Ultimate Strength Design are used for footing reinforcement, pier design, one way shear check, and taking different factors for various cases. Loads represent actions upon the structures into a form of force. A spatial distribution of loads upon the structure is called a load case. An unlimited number of load cases can be defined in AFES. Separate load cases would be defined for dead load, live load, wind load, operational load, test load, etc. You can create limitless load combinations from the defined load cases as the program offers default load combinations that are editable. Load cases include self weight, which the program has an option if it shall be included. Wind or earthquake load definitions are also available when using the Ball Tank equipment type. The Load Case and Combination window can be accessed by the Load Case/Combination button.

Note: The following are load considerations taken for Heat Exchanger and Horizontal Vessel Foundations.
a) Bundle Pull (Exchangers) Bundle full force is an estimated friction force generated from exchanger tube bundle installation or removal. This load is applied longitudinally at the center of the bundle and distributed between the piers. For stacked exchangers, the load is applied at the center of the 153 of 272
top bundle. The portion of the bundle pull force at the sliding end support is calculated as the
lesser of the friction or ½ the bundle pull force and the remainder is resisted at the fixed end support.
b) Thermal Force Thermal force is the force due to the growth of the horizontal vessel or exchanger between supports. Thermal growth is calculated using the maximum design temperature.
Smaller value resulting from the following calculations is used as thermal force and is applied at the top of the piers.
c) Force required to overcome static friction between the vessel support and side plate. Ff = μ (Pop)
where, Ff
= static friction force
μ
= coefficient of friction
Pop
= operating compressor load on slide plate
d) Force required to deflect the pier or column an amount equal to ½ of the thermal growth between supports. Fd = 3 Δ EI/2L3
where, Fd = pier deflection force Δ = total deflection between piers E = modulus of elasticity I = pier moment of inertia L = distance between piers
a) Slide Plates A steel plate shall be provided at the sliding end of every vessel regardless of the flexibility inherent in the structural support.
154 of 272
Use low friction slide plates such as lubrite or Teflon for large movements or if the operating weight at the sliding end exceeds 25 kips. Exceptions to this are as follows:
b) When the deflection force Fd is equal to or less than the sliding force Ff for low friction bearing. c) When it is more economical to distribute a large load more evenly between the two piers by increasing the friction force on the sliding end.
Typical coefficients of friction are as follows:
- No slide plate (steel support on concrete)
0.50
- Steel Slide Plate
0.30
- Teflon Slide Plate - Bearing Pressure 100 psi and below
0.10
- Bearing Pressure Above 100 psi
0.06
- Lubrite Slide Plate
0.10
The following criteria are used in sizing low temperature (les than 500 degrees F) slide plate elements. Plate width: (Δ = total thermal growth between plates) a) lower element = (saddle width) + 2 (Δ) + ¼ in b) upper element = (lower element) + 1 in
Allowable bearing in psi: (T = saddle temperature in degrees F) - for T ≤ 100
2000
- for 100 < T < 500
2000 – 17 (T-100)/4
The thermal and friction forces are automatically calculated in AFES. After getting the values input manually the in the load case data.

When you are ready to analysis and design the foundation, you can click “Foundation Analysis/Design” icon from top toolbar menu below. or From the Main Menu select Design (D) > Run ( = Analysis) …> Rigid Method
17.1 General AFES executes Foundation Analysis and Design according to design standards widely accepted. It is assumed that all external forces are loaded at the center of the piers and the connection between the pier and the footing is considered to be rigid enough to carry those forces. Strength, stability and sectional design of components of footing, pier, corbels and tie girders are properly examined. The design codes of AFES support ACI318-99, 02, BS 8110, Korean and IS456 (2000). Some shapes of footing and pier are available for design and analysis with AFES. Usable footing shapes are rectangle, circle, octagon, circle with a hole, while available pier shapes are rectangle, circle, octagon, T-shape.
17.2 Design Method AFES supports “Automatic Analysis and Design” and “Manual Analysis and Design” at the same time.
17.3 Automatic Analysis and Design With externally loaded forces, AFES is able to do automatic analysis and design of foundations, which bring out optimized sections of a footing against stresses by the external loads. The application can proceed in analysis and design without detailed design data including the assumed size of a footing, the assumed number of piles, specifications on spacing, and types of reinforcement. After analysis and design, the recommend result can be saved in the database and seen in a summarized form.
Note : The load case and combination should be input before executing auto design.

26.2 Troubleshooting of OpenStaad Program
AFES can import Geometric, Load Case & Load Combination Data using OpenStaad Function. There might be problems importing data depending on installed Staad.Pro version. These kind of problems caused by OpenStadd and Staad.Pro version can be solved by resetting program
1. Run : Driver directory can be found in installed AFES directory. Run OpenSTAAD_patch\ OpenStaadSet.exe in subdirectory. Here is example of full path for executed file. EX)C:\ \Program Files\ \GS_AFES\ \AFES 2.5\ \Driver\ \OpenSTAAD_patch\ \OpenStaadSet.exe
2. Window for Running.
Installed OpenStaad Path This text box is shown as blank when not installed. In that case specify directory of where the installer is saved. Then choose from “Ver. 2004” or “Ver. 2005” of version you want to install. The program shall automatically perform installation Note: Close AFES and Staad programs before proceeding to installation of OpenStaad program otherwise it will Installation button You can install version 2004 or version 2005. Version 2004 is recommendable, but version 2005 is also available in some cases. Note: Ver. 2004 and Ver. 2005 are versions for OpenStaad macro not Staad.Pro program.
You can test OpenStaad. You can test existing sample files by [Test] command button, also test other files, which is not existing. (In this case, Other file should be analyzed using Staad.Pro.)
