a large beam, originally of wood or iron, now usually of steel or concrete, though light 447 alloys have occasionally been used. Apart from the bowstring girder its chords are parallel.

Girder

total bending effect at any section of a beam is called the bending moment. It is equal to thealgebraic sum of all the moments to the right of the section (or to the left of the 448 section, whichamounts to the same thing) and is called M for short. Every bending moment can be expressed as aforce times a distance called the arm. units are poundinches, ton-inches, kg-m, N-m, tonne-m, etc.

Bending moment

gravel, sand, slag, crushed rock or similar inert materials which form a large part of concretes,asphalts or roads including macadam.

Aggregates

in concrete or mortar, a substance other than aggregate, cement or water added in small quantity,normally less than 5% of the weight of the cement, to alter the properties of the mix or the hardenedsolid. Some 80% of the concrete made in North America, Australia, Japan and most of Europecontains an admixture, and more than half contains airentraining agent. Other admixtures are 450 accelerators, bonding admixtures, super plasticizers, water reducers, retarders, antifreeze,corrosion inhibitors, pore fillers and thickening agents. Shrinkage preventers, coloring (pigments),damp-proofing, expanding, fungicidal, gas-forming, grouting and flocculating agents also exist. Forconcretes with high cement needed to such an extent that the admixture pays for itself without harmto the physical properties. But this saving probably never occurs with very lean concretes.

Admixture

an admixture which hastens the hardening rate and/or initial setting time of concrete. Calciumchloride (CaCI2) was widely used, but because it can corrode embedded steel it is now banned inthe UK except in unreinforced concrete. Chloride-free accelerators that 451 are safe with steel are based on inorganic chemicals including formats, nitrates and thiocyanates. Sodium carbonate (washing soda) can be used to make a flash set for quick repairs but It weakens the concrete.

Accelerator

an admixture which slows up the setting rate of concrete, sometimes applied to formwork 452 so thatwhen it is stripped the cement paste which has been in contact with it can be removed by light brushing.

Retarder

449

453 making a hole in rock blasting, using a rotative or percussive drill. 454

piece of steel plate, usually roughly rectangular or triangular, w/c connects the members of a truss.

When a heavily loaded column punches a hole through a base, the base is said to fail by punching shear. Punching shear is prevented by thickening the base or enlarging the 455 foot of the column so that the shear stress (assumed uniform) round the perimeter of the column does not exceed twice the allowable shear stress in concrete.

456

for any material the ratio of the stress (force per unit area) to the strain (deformation per unit length).

457

the water content at the lower limit of the plastic state of a clay. It is the minimum water content at which a soil can be rolled into a thread of 3 mm diameter without crumbling.

Elastic Limit

Plastic Limit

the elastic movement of loaded parts of a structure. The word often refers to the sinking 460 of the midspan of a beam which in British housing generally is not allowed to exceed 1/325 of the span.

Deflection

the load acting across a bean near its support. For a uniformly distributed load or for any 461 other symmetrical load, the maximum shear is equal to half the total load on a simply supported beam, or to the total load on a cantilever beam.

Shear

462

Stress

Strain

464 a core wall.

Shear Wall

test for the stiffness of wet concrete. A conical mold is filled with concrete, well rammed, and then carefully inverted and emptied over a flat plate. The amount by which the concrete cone drops below the top of the mold is measured and is called the slump. This 465 test is valuable only when the aggregates are used all the time and in the same proportions. It then gives a rough idea if the water content of the mix. This otherwise most useful test cannot be applied to stiff concretes with slump of less than about 20 mm.

Slump Test

a structural member designed to resist loads which bend it. The bending effect at any 466 point in a beam is found by calculating the bending moment. Beams are usually of wood, steel, light alloy, or reinforced or pre-stressed concrete.

Beam

467 a post carrying compressive force.

Column

the bending moment at the support of a beam required to fix it in such a way that it cannot rotate, so that it has a fixed end.

Fixed End Moment

in concrete work, a break in a structure made to allow for the drying and temperature shrinkages (of concrete or masonry) thus to prevent cracks forming at undesirable 469 places. Since all materials containing cement' shrink appreciably on drying, contraction joints are needed in every long structure.

470 a pre-stressing bar, cable, rope, strand or wire.

Grade Beam



concrete members are pre-cast, in a works, with the tensioned wires embedded in them. The wires are anchored either against the molds or against permanent abutments in the ground. After hardening, the concrete is released from the mold and the wires are cut at the anchorage. This method may give a larger loss of pre-stress than with posttensioning but is usually economical for small members and may produce better 472 concrete since it is always factory controlled. In long-line pre-stressing, used for the precasting of pre-tensioned floor slabs or beams, the casting bed may be as much as 180 m long; enabling units may be 1.2 m, and their thickness 15, 20 or 25 em. They usually have tubular voids running down the length and occupying about 30% of the crosssection.

Pre-tensioning

concrete beams, columns, lintels, piles, and parts of walls and floors which are cast and partlymatured on the site or in a factory before being lifted into their position in a 473 structure. Where many of the same unit are required, pre-casting may be more economical than casting in place, may give a better surface finish, reduce shrinkage of the concrete on the site, and make stronger concrete.

Pre cast Concrete
