COMPARATIVE ANALYSIS OF G+23 BUILDING WITH VARIOUS SLENDERNESS RATIOS BY USING ETABS SOFTWARE

Abstract

The behavior of a building during earthquakes depends critically on its overall shape, size and geometry. Earthquake resistant design of buildings depends upon providing the building with strength, stiffness and inelastic deformation capacity which are great enough to withstand a given level of earthquake generated force. This is generally accomplished through the selection of an appropriate building configuration and the careful detailing of structural members. Configuration is critical to good seismic performance of buildings. The important aspects affecting seismic configuration of buildings are overall geometry, structural systems, and load paths. The building slenderness ratio and the building core size are the key drivers for the efficient structural design. This paper focuses on the effect of Slenderness Ratio of the building frame, B is the Base width and L is the Length of the building frame with different Plan Configurations on the Seismic Analysis of Multistoried Regular R.C.C. Buildings. The slenderness ratios assumed are 3.00, 3.60, 4.80 and 7.20 with varying building widths as 25m, 20m, 15m and 10m. The analysis results like storey drift, storey shear, storey bending, building torsion, time period, model stiffness values are compared with all the aspect ratios for G+23 building by using ETABS Software.
