Experimental Investigation of RC Frame with Sway Columns Under Corner Column Removal Scenario

Although the progressive collapse has a small probability in economically developed countries, it can lead to catastrophic consequences. Therefore, this paper is aimed to experimental and numerical investigation of impact parameters on the reinforced concrete frames under scenario of sudden column removal. As well as it provides the analysis of the failure mechanisms of the frame under consideration, and substantiation of the criteria for assessing these failure mechanisms. For the purposes of the study, a two-story reinforced concrete scaled frame was designed, manufactured and tested. A nonlinear dynamic and quasi-static analysis of reinforced concrete frame have been performed using finite element bar models both of the structure and leverage loading system. Numerical and physical modeling of an accidental impact such as sudden removal of the corner column of the shows that the exhaustion of the load capacity of eccentrically compressed column of a structural system can be caused by the stability failure.
