Review Paper on Seismic Analysis of Diagrid Structures was Conducted in Various Seismic Zones of India, Considering Both Soft and Hard Soil Conditions

Improving high-rise buildings involves a myriad of complex factors, including finance, aesthetics, technology, urban regulations, and politics. However, among these factors, finance has emerged as the primary governing element. In tall structures, the structural design is largely governed by its lateral stability. In this context, diagrid structures have demonstrated their ability to efficiently withstand lateral seismic loads through their unique corner-to-corner connectivity, which sets them apart from conventional orthogonal structures like framed tubes. Diagrid structures offer exceptional structural efficiency while also introducing new aesthetic possibilities in tall building architecture. Their distinctive appearance is easily recognizable and visually appealing. By minimizing the need for vertical columns on the facade, diagrid systems reduce obstructions to the external view, enhancing the overall visual impact. Moreover, the efficiency of the diagrid system allows for the elimination of interior and corner columns, providing significant flexibility in floor planning. This review paper presents an in-depth analysis of the seismic behavior of diagrid structure frames under varying soil conditions in different seismic zones of India. The focus is primarily on evaluating the response of diagrid structures in both soft and hard soil conditions, and their performance in mitigating seismic forces. The paper examines the design considerations, analytical techniques, and case studies pertaining to diagrid structures in seismic regions of India.
