| Abstract | Experimental studies are carried out to understand facts or details on the seismic performance and failure mechanisms of bonded post-tensioned interior slab-column connections. Two 3/5-scale models of bonded post-tensioned interior slab-column connections were tested to failure. The first model was designed and constructed to represent a typical connection between interior column and post-tensioned flat plate with bonded tendons usually found in low to moderate seismic regions, such as Thailand, where seismic provisions is not normally a consideration in design. The second model was intended to represent an improved design by adding a drop panel. The parameter introduced in the experimental program is the gravity shear ratio on the slab critical section. Minor detailing changes in the reinforcement distribution and anchorage were also introduced to the second model. The presence of a drop panel and these changes effectively enhance the connection performance in terms of increased lateral load-carrying capacity, drift capacity, stiffness, and energy absorption. Punching shear strength and drift capacity were compared with relevant design equations suggested by ACI 318-08 Building Code provisions as well as previous tests by others. Results from this study indicate that the existing ACI provisions can be applied when designing bonded PT interior connections. |
