A New Method For Estimation For Estimation Of Seismic Behaviour Of Setback Buildings

Abstract

A Setbacks are widely used in modern architecture because of the aesthetic and practical benefits they give. However, the existence of setbacks diminishes the structure's floor area and affects its mass and stiffness, resulting in variances in the building's dynamic behaviour. Seismic design codes sometimes ignore this component, resulting in structure collapses during earthquakes. This research offers a new index for setback structures to replace and improve on code-based indexes. The suggested index's ability to concurrently quantify mass, stiffness, and strength irregularity proves its effectiveness in assessing setback irregularity.
