Model and Analysis of Earthquake on Multi-storey Buildings using ETABS software

The structural analysis software plays an important role to carry out the seismic calculation for the infrastructures. In this modern period of time, where computer has reached every phase of life, using the traditional book system for analytical development of the students, which is no doubt necessary, is no longer sufficient. Moreover, construction and design has become so much competitive in this world that using computers became mandatory. In this chapter, an introduction to the structural analysis software ETABS has been presented. Different features of the software have been highlighted which was used to carry out the analysis work presented in this book. ETABS stand for Extended Three Dimensional Analysis of Building Systems. ETABS is generally used to modelling and analyse low and high rise buildings, skyscrapers, parking garages, steel and concrete structure, portal frame structure. The case study in this mainly accentuate on the structural behaviour of a multi-story building for the different plan configuration. Modelling of 75 story R.C.C. building is done on the ETABS software for analysis. Post analysis of the structure, maximum shear forces, bending moments, displacements due to dead load, live load, wind load, earthquake load are computed and then compared for all case analysis.
