INTRODUCTION

As the requirements of course BFC32803 Structural Concrete design 2, we was required to design double storey building in a land at Johor Bharu district. With preplanning, we choose to design a 2 storey private building for residential. The area of the building is 160

LITERATURE REVIEW

The structural Eurocodes are European suite of codes for structural design, developed over twenty five years (Started since 1975). By 2010 they have effectively replaced the current. British Standard as the primary basis for designing buildings and civil engineering structures in the UK. Claimed to be the most technically advanced structural design codes in the world. Have been developed to improve the competitiveness of the European construction industry  both within and outside the European Union. Eurocode is actually a performance code which has more advantages over British Standard, which is a descriptive code. Eurocode should result in more economic structures than BS. RC is one of the principal materials used in many civil engineering application. Civil engineering application such as construction of building, retaining walls, foundations, water retaining structures, highway and bridges, it is a composite material, consisting of steel reinforcing bars embedded in a hardened concrete matrix. The  primary purpose of structural analysis is to establish the distribution of internal forces and moments over the whole part of a structure and to identify the critical design conditions at all sections. The type of analysis should be appropriate to the problem being considered. The following may be used: linear elastic analysis, linear elastic analysis with limited redistribution, and plastic analysis.

DISCUSSION & CONCLUSION

The design of this project started with the design of staircase. The G & R for the staircase design was chosen according to the criteria of the private building and also based on our length of the staircase. The stair consist of 2 flight and a landing which was designed separately. Design of frame analysis contribute around 40 percent of this project where the analysis was based on analysis of one level sub frame, analysis of two free joint sub frame, analysis of continuous beam and one free joint sub frame and analysis of wind load. The frame we chose to design consist of two different length and 4 span. The moment distribution was done using MICROSOFT EXCEL for analysis of one level sub frame . All the shear force and bending moment caused from the loading on frame was shown in shear and moment envelope. For the design of column, we choose to pick 5 column which have different no of beam acting on the column. The max have 5 beam resting on it and the lowest have 2. The permanent load and variable load for each floor was determined first and the slab loading and self-weight of structure was included in the total load to find the axial force and moment in column. Then the total axial force was used to find the column where it’s slender or short. Most of all th

e

column was found to be  non-slender. Finally the no of bars needed to resist the moment was found and sketch at detailing. For the each column we design, we use the total axial load to design the pad foundation under the corresponding column. This higher load was acceptable to resist by pad foundation  because the higher amount of bars needed and the failure of punching shear where punching shear resistance was lower than punching shear force in the axial force only design. This conclude that pad foundation should be in higher thickness than the one we design to resist the load but the increase in pad foundation weight can cause settlement which can contribute to failure. Throughout this project, we learned to find a suitable way to design a structure and improve our knowledge in understanding the use of EC and structural design.
