摘要:
试件参数包括竖向钢筋连接排数(单排或双排)、竖向钢筋连接数量(全部或部分连接)以及内叶墙板、保温层和叶墙板厚度(分为200 mm+50 mm+60 mm与100 mm+50 mm+100 mm两种).研究结果表明:6片剪力墙均发生受弯破坏;现浇剪力墙与200 mm+50 mm+60 mm预制剪力墙具有相近的耗能能力和位移延性,100 mm+50 mm+100 mm预制剪力墙的耗能能力和位移延性则稍差;采用单排全部钢筋连接方案的预制剪力墙的承载力、位移延性、耗能能力均与采用双排全部钢筋连接方案的剪力墙相近,而采用单排部分钢筋连接方案的预制剪力墙承载力与位移延性稍大,耗能能力则基本相同.
Abstract:
Tests of five full-scale precast concrete sandwich insulation shear walls and one cast-in-place(CIP)concrete shear wall were carried out under low reversed cyclic loading. The main parameters of specimens are row number of connected vertical reinforcing bars(single-row or double-row), number of connected vertical reinforcing bars(full or part), thickness of external concrete wythe, insulation layer and internal concrete wythe(two kinds of cross sections of precast specimens with 200 mm+50 mm+60 mm and 100 mm+50 mm+100 mm respectively). The results show that all specimens fail in bending. The CIP concrete and the 200 mm+50 mm+60 mm precast shear walls exhibit similar energy dissipation and displacement ductility. Comparatively, the energy dissipation and the displacement ductility of the 100 mm+50 mm+100 mm precast shear walls are slightly poor. In addition, the bearing capacity, displacement ductility and energy dissipation of precast walls with single-row full connected vertical reinforcing bars are similar to those of the walls with double-row full connected reinforcing bars. In comparison, the former two capacities of precast walls with single-row partially connected vertical reinforcing bars are relatively higher. The energy dissipations of these three kinds of precast walls are almost the same.
