现浇板对RC框架结构抗震性能影响的试验研究
摘要:    为了解现浇板对RC框架结构抗震性能的影响,对两个框架结构进行了水平低周反复荷载试验,分析了其破坏形态、滞回性能、骨架曲线和刚度退化等性能。结果表明:现浇板的存在,提高了框架结构的承载能力,耗能能力变化不大,变形能力降低,破坏机制使其由“强柱弱梁”变为“强梁弱柱”。

Study on the Seismic Performance of RC Frames Structure with Cast in Situ Slabs
Abstract:      In order to study the affection of cast in-situ slabs in RC frames during earthquakes, this paper presents a low cyclic loading test for two RC frames. To analyze the performances of failure mode, hysteretic behavior, skeleton curve, stiffness degradation etc, study the impact of construction joints to the overall seismic. The results showed that the exist of cast in-situ slabs improved the carrying capacity of the frame structure, reduced the deformability of RC frames structure and little change in energy dissipation capacity, the failure mechanism happened from “strong column-weak beam” to “strong beam weak column”.
Keywords:  Cast in-situ slabs  Low cycle reversed lateral load  Seismic performance
