Effect of Building Geometry on its Performance Under Earthquake and Wind Loading

Abstract

Recently new trend generated to resist lateral forces using truss system called as diagrid structure. Diagrid structural system adopted to resist lateral load due to its structural efficiency and flexibility of architectural planning. This study report contain effect of geometry of structure on its performance. To find out effect of geometry of structure on performance. Comparative analysis is done on circular and square shaped diagrid steel structure under earthquake and wind loading. To analyse models under earthquake and wind loading, response spectra method and gust factor method are adopted respectively. E tabs 2015 software used for modelling and analysis of diagrid steel structure. The loading conditions is based on their action of transmission like wind loading acting exposed surface to ground and earthquake loading acting ground to structure. Comparison of structural performance is done on the basis of storey displacement, storey shear, time period, material consumption.
