Özet
The purpose of the study is to investigate progressive collapse resistance of a reinforced concrete building taking soil–structure interaction into account. The study has been conducted on a five-storey school building that was designed seismically before. The progressive collapse potential of the building is investigated using the alternate path method for linear static and nonlinear dynamic procedures according to the guideline of United States Department of Defence United Facilities Criteria, Design of Buildings to Resist Progressive Collapse. The modified Vlasov model is used here for the first time to include the soil–structure interaction effect on the progressive collapse risk of a reinforced concrete building. A programme was coded in MATLAB to interact with SAP2000 via Open Application Programming Interface (OAPI) features simultaneously for this purpose, and the subsoil effect on the structure was investigated. Two types of column removal scenarios are examined to investigate the effects of soil–structure interaction on progressive collapse resistance. It has been observed that the building under investigation has sufficient resistance to progressive collapse, but when soil–structure interaction is considered, there is increases in the internal forces of the structural elements in general. There may be a possibility that the safety of some other structure will be adversely affected due to the additional effects on the internal forces caused by subsoil. Therefore, at the end of the study, it was concluded that subsoil effects must be taken into account in the progressive collapse analysis.
