Seismic Performance of Precast Reinforced Concrete Core Wall with Horizontal Tied Rebars at Mid Height Level of First Story

摘要

Precast core walls are considered effective for construction because they can be built more quickly than cast-in-place core walls. Previously, we conducted a lateral loading test on a full precast wall column simulating the area near the corner of an L-shaped core wall in order to examine the seismic performance. The wall column was divided into precast columns, and horizontal tied rebars were concentrated at the second and third floor levels to connect the precast columns. In this study, a lateral loading test was conducted on a wall column to which horizontal tied rebars were added at the mid height level of the first story. Based on the results of the test, the seismic performance of the wall column was clarified.
