SEISMIC ANALYSIS AND DESIGN OF A MULTI STOREY BUILDING

Abstract

This report has been prepared as part of project work to fulfill the requirement of course syllabus prescribed to Civil Engineering final year course. Our project group has chosen to do analysis and design of Reinforced Concrete framed building under the guidance of our dedicated supervisor and department of Civil Engineering. Among the two category of building structure, via load bearing and framed structures, here, in the project work the frame structure is practiced. Building frame is the three dimensional structure as space which consist of rigidly interconnected beams, slab and columns. It produces greater number of the redundancy thus reduces the moments and facilitates the even distribution of the load. Comparing various models of building structures, we found Commercial building as the most challenging project. Thus, we have given preference to the construction of the frame structured seven storey commercial building with basement, shear wall, lift, flat roof. Building frame is the three dimensional structure as space which consist of rigidly interconnected beams, slab and columns. It produces greater number of the redundancy thus reduces the moments and facilitates the even distribution of the load. This project enabled us to acquire knowledge on proper analysis and design of building for earthquake safety including the capability of solving and tackling the field problem to somewhat. It has taught us to work in team which will surely help us in the future to come. The results of calculation are presented in tabular form and sample calculations are provided in details to reduce the bulkiness of the report. Sufficient figure and sketches have been introduced to illustrate the theories. Reference to the appropriate clauses of standard codes of practices has been made wherever necessary. It is clear that for understanding the process physically and realizing the structure behavior, manual steps by steps procedure is necessary. However due to the time constraint and to be familiar to the modern technology, the structural analysis and design part is performed using computer software “SAP”. The burden of repeated calculations in analysis has been reduced due to use of computer software. Report is focused on the design of slab, beam, column (rectangular), staircase (open-well) and foundation (mat footing).
