Seismic Analysis of Diagrid Structure on Sloping Ground

Abstract

Lateral efficiency of a building is very important in high-rise buildings, when it comes to building them on sloping ground it is highly required to design the structure for wind load and earthquake loads. The diagrid structure thus provides very high lateral stability and reduces the lateral displacement of the building. In recent years the diagrid structure has attracted many researchers and scholars due to this greater structural efficiency. Diagrid structural system has evolved to be structurally the most efficient, aesthetically pleasant and highly economical. The present paper involves the study of diagrid structure on sloping ground and comparing it with the conventional system and finding the optimum angle of diagrid on different slopes of ground. A 12- storey building is used for comparing diagrid structure and conventional structure on sloping ground, a 48 storey building is used to find out the optimum angle of diagrid on sloping ground, ETABS software Is used for modelling and analysis, response spectrum method is used for analysis, the results show that diagrid structure is more efficient than conventional structure on sloping ground, and the optimum angle of diagrid lies between 60-75° on sloping ground.
