Progressive collapse refers to the failure of a structure or a part of a structure that initiates a chain reaction, leading to partial or total collapse. In multi-story buildings, progressive collapse can result from unexpected events such as earthquakes, structural irregularities, or localized damage. This study focuses on assessing the progressive collapse potential of a G+6 multi-story building using the guidelines provided in IS 1893: Part 1 (2016) –Criteria for Earthquake Resistant Design of Structures. Using linear and nonlinear static analysis, key structural parameters including story displacement, story drift, base shear, andstory moments are evaluated to understand the building’s response under seismic loading conditions. The results provide insight into the weak points of the structure, allowing engineers to implement design modifications to enhance resilience. The study highlights the importance of compliance with IS 1893 for ensuring structural stability and mitigating the risk of progressive failure in multi-story buildings.

Key Words:-Progressive collapse, multi-story building, displacement, story drift, base shear, andstory moments
