摘　　要：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-cycle reciprocating test of cancelled-reinforced concrete frame and infilled- wallboard reinforced concrete frame, the influence of flexible-connected infilled-honeycomb-sandwich wallboard on seismic performance of the frame was analyzed. Through comparatively analyzing the physics experiment result of the two type frames,it is concluded that the infilled-wallboard is co-oper- ated with frame in early stage of loading. At the same time the infilled-wallboard enhances the capaci- ty of anti-sidesway of frame in elasticity stage. In ultimate limiting state, the bearing capacity of in- filled-wallboard frame is higher than the cancelled frame, and there is no significant difference on anti- sidesway between the two type frames. There is no significant influence on velocity and degree in stiffness-degrade of frame from infilled-wallboard, as the major factors of rigidity-degrade of frame are concrete-crazing and bar-deformation.
