  • Abstract:
  • Recent trends indicate that the unique geometric design of diagrid structural systems has made them increasingly popular in high-rise buildings, combining aesthetic appeal with structural efficiency. With the global rise in multi-story construction, diagrid systems are being widely adopted. These systems are among the most effective methods for countering lateral forces, as they enhance both the structural integrity and visual design of buildings. Research has highlighted that the primary causes of R.C. structural failures are the abnormal distribution of weight, stiffness, and strength, or irregular geometric configurations. Many existing buildings exhibit defects resulting from operational and aesthetic demands. Engineers must prioritize earthquake-resistant designs to limit damage to acceptable levels, safeguarding occupants' lives at a reasonable cost. Earthquake-resistant structures are designed to withstand ground shaking; while they may sustain severe damage, they are built to avoid collapse during strong earthquakes. This study compares irregular steel structures with and without diagrids under earthquake conditions specified in IS 1893:2016. The analysis considers an irregular steel building with a configuration of B+G+19 stories, a plan dimension of 24m x 24m, situated in seismic zone IV with medium soil conditions. The modeling and analysis are conducted using ETABS 2019 software, and all structural components are designed in accordance with IS 456:2000. The study evaluates the performance of both steel buildings under dynamic analysis, considering wind effects, lateral forces, and load combinations as per IS code. Key parameters such as maximum storey drift, base reactions, storey stiffness, and storey forces are analyzed to assess the structures' behavior.
