Experimental research and numerical simulations of the actual response flat slab in case of column loss

Abstract

AbstractThis study reports the influence of tie reinforcement on the load‐bearing capacity of a flat plate slab in a failure situation due to the removal of an edge column. The results are based on numerical model analysis, experimental investigations, and analytical estimation. A numerical model was developed using the ATENA FEM program and validated based on the test results of the materials used. Experimental studies on the edge column removal were carried out for three models of 16 field flat plate slabs with varying degrees of tie reinforcement. Furthermore, the columns removed in Models M1 and M2 were near the corner edge columns, whereas in Model M3, they were the middle edge columns. The behavior of a reinforced concrete flat plate subjected to large deflections was estimated analytically based on the current literature and compared with the results obtained from numerical analyses and experimental investigations. During the experimental investigations, many traditional and modern techniques were used to measure the strains and displacements of reinforcing steel and concrete.
