| 摘 要： | 按照"强节点弱构件"的思想,设计并完成了5个不同配筋形式的足尺现浇钢筋混凝土空心楼板-剪力墙节点试件在板端往复荷载作用下的试验研究。试验结果表明:试件的破坏模式与预期模式相同,实测名义屈服荷载与设计承载力基本相符;试件空心板横截面满足平截面假定;边肋中布置箍筋或预应力筋均可提高空心板的抗剪承载力;试件的极限位移角大于1/40,其中弯曲破坏试件的极限位移角大于1/25,位移延性比大于4;试件的滞回耗能稳定,模拟实际配筋的试件J5相对耗能比最好。说明按照文中建议的设计方法,可以满足现浇钢筋混凝土空心楼板-剪力墙节点的抗震延性设计要求。

| Abstract: | According to principle of "strong joint and weak member",five full-scale cast-in-place reinforced concrete hollow slab-shear wall joint specimens with different reinforcement details have been tested under reversed cyclic loading.From the experimental results it is found that the real failure modes of the five specimens are the same as the designed failure modes.The measured nominal yield loads of the 5 specimens are close to the predicted values.Measured reinforcement strain distributions at the different ... |
