STRUCTURE ANALYSIS AND EARTHQUAKE RESISTANT DESIGN OF COMMERCIAL 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. Among several projects which were offered to us, we have chosen the project entitled “Structural Analysis and Earhquake Resistance Design of Commercial Building” under the guidance of our dedicated supervisor and Department of Civil Engineering. Comparing various models of building structures, we found public building as the most challenging project. Thus, we have given preference to the construction of the frame structured eight-stories commercial building with basement, shear wall, lift. 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 behaviour, 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 2000 V-16”. 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 (primary and secondary), column (square), staircase, and foundation (raft foundation and isolated footing).
