Structural Analysis of Diagrid and Regular Building Structure by Using Staad-Pro

Abstract

The latest trend in high rise building is diagrid structures because of structural and architectural effectiveness. In the study previous literatures are studied for Flat-slab Building and detailed analysis is carried out to check the behaviour of flatslab buildings with and without diagrid. It is very important that the selected structural system is such that the structural elements are utilized effectively while satisfying design requirements. Recently diagrid structural system is adopted in tall buildings due to its structural efficiency and flexibility in architectural planning. Structural design of high-rise buildings is governed by lateral loads due to wind or earthquake. Lateral load resistance of the structure is provided by interior structural system or exterior structural system. Due to inclined columns lateral loads are resisted by axial action of the diagonal in diagrid structure compared to bending of vertical columns in conventional building. This paper also reviews the studies on the comparison of diagrids with regular configuration and diagrids with varying angles. The analysis and comparison of diagrid and conventional structural system on the basis of consumption of steel, structural weight and displacement are also highlighted.
