| 摘 要： | 对3榀再生混凝土框架顶层边节点的抗震性能进行了试验研究。试件节点区域采用三种不同的配筋形式,在低周反复荷载下观测试件破损特点、发展过程及最后破坏形式,得到梁端荷载-位移滞回曲线,对3榀试件滞回特性、位移延性、刚度退化和耗能能力进行了研究。结果表明配筋形式对再生混凝土框架顶层边节点的抗震性能有一定影响;再生混凝土试件可用于有抗震设防要求的工程。

| Abstract: | The seismic behavior of three recycled aggregate concrete(RAC) frame knee joints specimens with different detailing schemes was tested.The crack distribution and damage map,development of crack and the final failure modes of the specimens were observed under the low-frequency reversed lateral loading.The seismic behavior of recycled aggregate concrete frame knee joints such as hysteresis characteristics,displacement ductility,stiffness deterioration and energy dissipation was analyzed based on the test resu... |
