Seismic Analysis of a Multi-Storeyed Building with Irregular Plan Configuration Using ETABS

It is an attempt to investigate the effect of Irregular plan configuration for multistoried reinforced concrete building model.This paper mainly emphasizes on analysis of a multi-storey building (G+25) which is irregular both in plan and elevation. Modelling of 25 storeyed R.C.C. framed building is done on the ETABS v13.2.0 software for analysis. Post analyses of the structure such as Maximum Storey Displacement, Base Shear, Storey Drift, Maximum base reactions, Torsion and Over-turning moments are computed and then compared for all the analysed cases. ETABS is an engineering software product that caters to multi-story building analysis and design. ETABS stands for Extended Three dimensional Analysis of Building Systems. Basic or advanced systems under static or dynamic conditions may be evaluated using ETABS. Design of steel and concrete frames (with automated optimization), composite beams, composite columns, steel joists, and concrete and masonry shear walls is included, as is the capacity check for steel connections and base plates. ETABS provides an unequaled suite of tools for Structural Engineers designing buildings, whether they are working on one-story industrial structures or the tallest commercial high-rises.
