Dynamic Analysis of Irregular Steel Building with or Without Diagrid Structure

Abstract

In this paper, our work presents the comparison of irregular steel structures with or without diagrids according to earthquake conditions proposed in IS 1893:2016. An irregular 2B + G+18 story steel building with plan size (15 m x15 m), located in zone IV having medium soil conditions is considered for analysis. The modelling and analysis are carried out using ETABS 2019 software. All structural members are designed as per IS456:2000. Analysis and study of both steel buildings, taking into account the dynamic analysis along the wind and the lateral effects of the wind and all load combinations confirming the I.S code. Building models are analyzed by ETABS 2019 software to study the effect of maximum storey displacement, maximum storey drift, base reactions, storey stiffness and storey forces etc.
