Progressive Collapse Evaluation Of An Industrial Building – Numerical Approach

The paper presents the evaluation of the potential of occurrence and propagation of the progressive collapse for an industrial building made of precast and cast in place elements. A model was developed for the numerical evaluation using the method of applied elements and a demolition scenario was used through which the column was instantaneously removed. The potential of occurrence and development of collapse was studied, using scenarios of column removal in according to GSA 2003 as well as scenarios in which two or three columns were removed. The evaluation was based on the determination of the rotations of the beam ends. The obtained results highlighted the importance of the manner in which the structure is designed and built, of the height regime and structural conformity, on the collapse.
