Progressive collapse resistance of a 13-story RC building subjected to different “missing column” scenarios

Abstract

In this paper, the progressive collapse resistance of a typical 13-story RC-framed structure is assessed. The building is subjected to three damage scenarios by the removal of a corner column from the 1^st floor, from the 7^th floor, and from the 13^th floor. According to GSA (2003) Guidelines, nonlinear dynamic analyses are performed in the ELS® computer software, which is based on Applied Element Method. It was shown that, under the standard GSA loading = DL+0.25LL, the building is not expected to fail. Moreover, the 13-story structure collapses under the gravity loads of 1.65(DL+0.25LL) when the corner column is removed from the 1st floor or from the 7^th floor and under 1.80(DL+0.25LL) when the column is removed from the 13^th floor.
