Buckling Analysis of Multi-Storey Steel Building with and without Bracing under different Soil Conditions

Abstract

The major concern in the design of multistoriedtall steel building is to have good buckling load resisting system along with gravity load system because it also governs the design. This paper is presented to show the effect of different types of bracing systems in multistoried tall steel buildings on buckling behavior of the structure under different soil condition. For this purpose, multi storey steel building models without and with different bracing systems such as Diagonal, X bracing, inverted‘V’ bracing and K bracing system under different soil condition. A commercial software package ETABS is used for the analysis of steel buildings and different parameters are compared with buckling factors. The property of the section is used as per IS 800:2007 which incorporates Limit State Design philosophy.
