Comparison of the Structural Performance of Monolithic and Precast Reinforced Concrete Core Walls

摘要

In the core wall system in high-rise buildings, the four L-shaped core walls at the center effectively reduce seismic vibration. On the other hand, precast core walls are effective for construction because they can be built more quickly than cast-in-place core walls. In this study, a lateral loading test was conducted on a monolithic wall column simulating the corner and the area near the corner of an L-shaped core wall. The test results were compared with those of a precast wall column tested previously. The precast wall column was divided into precast columns, and horizontal tied rebars were concentrated at the second and third floor levels, and the mid height level of the first story. Based on a comparison of the results of lateral loading tests with monolithic and precast wall columns, the structural performance of these wall columns was clarified.
