Abstract
Since the effect of the irregularity in height of medium and tall structures has a great influence on lateral behavior of structures and it also affects the design of the sections, in this study, various scenarios of sudden column removal in different locations of steel structures with and without geometric irregularities in height have been investigated. The Alternate load Path Method (APM), Nonlinear Dynamic Analysis (NDA), and OpenSees software were used to investigate 10, 15 and 20-story buildings with three types of irregularity in four different column removal scenarios.
The results show that increasing the irregularity in height increases the response of the structure. Also, the response of the structure to the sudden removal of columns in short buildings is greater than high-rise buildings. In other words, as the floors and elements in the buildings decreases, the potential for the progressive failure, increases.
