Irregular buildings constitute a major fraction of the urban infrastructure due to various occupational and architectural demands. Most buildings are irregular to varying degrees due to asymmetry in plan, elevation, distribution of vertical members or mass distribution on the floors. This study presents a comparison of code IS 1893 (2016) and its amendment issued in November 2020. A (G+7) building, situated on Type II soil in seismic Zone V, was considered for the purpose of investigation. The analysis is carried out using STAAD.Pro CONNECT Edition Version 22. Four rectangular models were analyzed and story displacements were considered for torsional irregularity. The results reveal that the 2020 amendment of IS 1893 has made the criteria for identifying torsional irregularity more lenient in comparison to IS 1893 (2016) recommendations, allowing greater structural flexibility.
Earthquakes are generated by a sudden release of the energy in the earth’s crust that creates seismic waves. Being one of the natural hazards, earthquakes have the potential for causing massive damages.
