ASSESSMENT OF PROGRESSIVE COLLAPSE IN ASYMMETRIC HIGH RISE BUILDING

Abstract

Progressive collapse is a critical safety concern in modern high-rise buildings, especially when asymmetry is present in the
structural design. Asymmetric buildings, due to irregular geometry, load distribution, and structural variations, pose unique challenges in terms of their vulnerability to progressive collapse. An asymmetric model of a 12storey structure is made on ETABS Software and analysis of reinforced concrete framed structure under critical column removal has been carried using the linear static analysis methods as per the guidelines provided in GSA (2003) and FEMA: 356 guidelines respectively taking into consideration the provisions of IS1893:2016 codes to simulate dynamic collapse problems.
