Progressive collapse of multistory 3D reinforced concrete frame structures after the loss of an edge column
Original language description
Due to the frequent occurrence of natural disasters and terrorist attacks, research on resisting progressive collapse has attracted increasing attention from the engineering and academic communities. Numerous experimental studies conducted in recent decades have focussed on single-story 3D structures, however, there are many differences between single-story 3D structures and multistory 3D frames due to spatial effects. Therefore, a 1-bay-by-2-bay two-story reinforced concrete (RC) frame with the loss of one edge column was constructed, tested and analysed in this study. The collapse phenomena, load-displacement curves, lateral displacements and axial load distributions were recorded and discussed. Furthermore, the effect of the slab on the progressive collapse resistance of the multistory 3D frame without one bottom edge column was investigated using ABAQUS software. Moreover, a previously presented dynamic resistance model was modified in this article, and the contributions of the beams and slabs to the progressive collapse resistance of the multistory 3D frame were theoretically analysed. The slabs and beams in these frames could contribute approximately 1/3 and 2/3 of the load resistance, respectively.
