Shake Table Test of a Three‐Storey Confined Precast Prestressed Hollow‐Core Wall Building

ABSTRACT A confined precast prestressed hollow‐core wall structure was proposed to improve the construction efficiency of the building. The system comprises three standardized components that are prestressed hollow‐core wall panels, precast confined frames, and prestressed hollow‐core floor slabs, with in‐situ concrete for topping and beam–column joints. To verify the seismic performance of the system, a shaking table test was conducted on a full‐scale three‐story building that was designed using the proposed concept. The building was subjected to several shaking table tests with a range of intensity ground motions, incorporating both unidirectional and bidirectional loading. The test results showed that the structural system performed effectively during the intense series of tests. The building exhibited good seismic performance and achieved the performance objectives. The damages were mainly concentrated at the hollow‐core wall toe and the horizontal and vertical connection joints between wall panels. The damage state was low and did not result in strength reduction of the building during DBE earthquakes. The test results validate the seismic safety of the system, demonstrating the proposed system is a reliable solution for precast construction.
