Study on Structural Performance of Full Precast Reinforced Concrete Core Walls

Multistory core walls installed in high-rise reinforced concrete buildings effectively reduce seismic vibration. On the other hand, full precast core walls are considered effective for construction because they can be built more quickly than cast-in-place core walls. In this study, lateral loading tests were conducted on full precast wall columns simulating the corner and the area near the corner of the L-shaped full precast core wall. The specimen consisted of four square-section precast columns. The vertical joints between the precast columns were grouted with high-strength mortar. Each precast column had cotters at the vertical joint. Based on the results of the lateral loading tests, the structural performance of full precast core wall was clarified.
