Seismic Performance of Bonded Post-Tensioned Slab-Column Connections with and without Drop Panels
Two 3/5-scale models of bonded post-tensioned slab-column connections, one without drop panel and one with drop panel, were tested to failure. The study's goals were to: (1) develop information on the seismic performance of typical bonded post-tensioned slab-column connections; and (2) improve the seismic performance using a drop panel. A lateral quasi-static cyclic loading routine, simulating earthquake actions, was applied to the models' top columns. Overall performance was examined and compared in terms of lateral load-carrying capacity, maximum drift, stiffness, energy absorption, and failure mechanism. Relevant design equations suggested by ACI 318–08 Building Code provisions for preventing stress-induced and deformation-induced failures as well as previous similar tests by others were compared with test results. Results indicate that ACI provisions could be used for these connections, and the presence of a drop panel is an effective way to greatly enhance the overall performance of this type of connection.
