竖向钢筋采用不同连接方法的预制钢筋混凝土剪力墙抗震性能试验

介绍了5个剪跨比为2.25的钢筋混凝土剪力墙试件的拟静力试验，其中1个为现浇墙，4个为竖向钢筋采用不同连接方法的预制墙。试验结果表明：预制墙试件与现浇墙试件的破坏形态基本相同，为边缘构件竖向钢筋受拉屈服、墙底混凝土受压破坏；套筒浆锚连接能有效传递钢筋应力；套箍连接试件的预制墙与底部现浇部分发生面内错动，其极限位移角和耗能能力最小；预制墙试件的极限位移角大于1/100；轴压力作用下的正截面承载力试验值大于现行规范公式计算值。根据试验结果，提出了预制剪力墙需进一步研究的建议。图13表6参5

Tests on seismic behavior of pre-cast shear walls with various methods of vertical reinforcement splicing

Quasi-static tests of five reinforced concrete shear wall specimens with aspect ratio of 2.25 are introduced in this paper.Among the five specimens,one was cast-in-place wall specimen,and other four were pre-cast wall specimens with different methods of vertical reinforcement splicing.The test results indicate that the failure mode of the pre-cast wall specimens is the same as that of the cast-in-place wall specimen,i.e.,tensile yield of the vertical reinforcements in the boundary elements and compressive f...
