Study on Structural Performance of Full Precast Reinforced Concrete Core Walls

在高层钢筋混凝土建筑中安装多层核心墙能有效地减震。另一方面，全预制核心墙被认为是有效的建筑，因为它们可以比现浇核心墙更快地建成。本文进行了模拟L型全预制核心墙墙角和墙角附近区域的全预制墙柱的水平荷载试验。试件由四根方形截面预制柱组成。预制柱之间的竖缝采用高强砂浆灌浆。每根预制柱的垂直接缝处都有凹槽。根据水平加载试验结果，明确了全预制核心墙的结构性能。

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.
