Progressive collapse is a structure's entire or significant partial collapse after localized damage to a limited building area. Structures gradually collapse due to explosions, car accidents, fires, or other manufactured risks. The primary goal of the current research is to evaluate how steel constructions behave under unintended loads that might cause the structure to collapse gradually. The performance of the steel structure will be evaluated for sudden column loss as per the current guideline available for critical column removals like GSA or DOD. To study the behavior of steel building structures on the special moment resting frame (SMRF) under the progressive collapse G+10 structure is modelled in E-Tab (2018). In this work, the linear static (LS) analysis approach for single-column removal has been used to comprehend better the components taken into consideration, learn about progressive collapse, and get accurate findings for Demand-Capacity ratio (DCR), displacement of removal location, column's axial stress, notably in columns next to the obliterated column.
