通过对空腹和内嵌墙板的钢筋混凝土框架进行低周往复试验,分析柔性连接的内嵌蜂巢夹芯墙板对框架结构抗震性能的影响规律.通过对有、无内嵌墙板的2组框架物理试验结果的对比分析,结果表明:加载初期内嵌墙板即与框架协同作用,提高了框架弹性工作阶段的抗侧移能力;内嵌墙板框架最终极限状态下的承载力高于空腹框架,2组框架的侧移无显著差异;内嵌墙板对框架刚度退化速率和退化程度影响不大,这是由于框架试件的刚度退化主要来源于框架构件混凝土的开裂和钢筋受力变形等.
Through the low-frequency reciprocal test of reinforced concrete frame with fasting and embedded wallboard, the influence law of flexible connected inner-lining honeycomb sandwich panel on the seismic performance of frame structure is analyzed.Through two groups with and without embedded panel The results of frame physics test show that: the inner wall of the initial load will act synergistically with the frame to improve the anti-slip ability of the frame during the elastic working phase; the bearing capacity of the inner wallboard frame ultimate ultimate state is higher than the fasting Frame, there is no significant difference in the lateral displacement between the two frames; the inlay wallboard has little effect on the degradation rate and degradation degree of the frame stiffness, which is due to the stiffness degradation of the frame specimen mainly from the cracking of the frame member concrete and the deformation of the steel bar Wait.
