Two full-scale architectural precast concrete (APC) panels were tested in 2011 on a full-scale five-story steel frame building at the E-Defense shake table facility in Miki, Japan. The panels were designed according to common U.S. practice. The main issues evaluated were: 1) the effect of acceleration on the APC panels, and 2) the effectiveness of the current slotted-bolt sliding connection to allow for inter-story earthquake motion. The testing represented one type of standard US APC façade design where the APC panel is designed to accommodate inter-story drift through rocking. Instrumentation measured the acceleration of the panels and floors as well as the movement of the slotted connections. The difference between the inter-story drift at the center and corner of the building was large enough to suggest that it may be inaccurate to consider the drift at the floor center to be the same as the drift at the actual panel location, when trying to predict the behavior of an APC panel. Neither panel experienced damage at maximum recorded inter-story deflections of 13.1 and 22.7 mm (maximum out-of-plane and in-plane deflections). Displacement and acceleration data from instruments placed on the panels themselves suggest a possible correlation between vertical acceleration recorded on the APC panel and the occurrence of uplift at the base slotted connection (possible rocking). Acceleration amplification ratios were developed as well.
