COMPARATIVE ANALYSIS OF HIGH-RISE DIAGRID STRUCTURES WITH DIFFERENT PLAN SHAPES (RECTANGULAR AND PLUS SHAPE) IN SEISMIC ZONE III UNDER STATIC, RESPONSE SPECTRUM AND WIND ANALYSIS

High-rise buildings are increasingly being constructed in urban areas due to rapid 
population growth and limited land availability. The structural system plays a significant role in 
ensuring the stability, safety, and efficiency of such tall structures. Among the modern structural 
systems, the diagrid system has gained significant attention because of its ability to efficiently 
resist lateral loads through a network of diagonal members, reducing the requirement of 
conventional vertical columns. The diagrid system improves structural stiffness, architectural 
flexibility, and overall performance of high-rise buildings under seismic and wind forces. 
This study presents a comparative analysis of high-rise buildings with diagrid structural 
systems having different plan configurations, namely rectangular and plus (+) shapes, located in 
Seismic Zone III. The primary objective of the study is to evaluate and compare the structural 
behavior of these plan shapes under lateral loads. The analysis is carried out by considering the 
same building height and structural parameters for both configurations to ensure a consistent 
basis for comparison.
