- Abstract:
- The low-cycle loading test of two staggered slab-column-boundary beam joints was carried out to study their seismic performance. The crack development, load-displacement relationship, displacement ductility, and energy dissipation performance of the staggered slab-column joints(SSCJ)were studied. Experimental results reveal that both specimens present short-column brittle shear failure. Furthermore, an obvious hysteretic curve pinching phenomenon occurred. Thus, it can be concluded that the seismic performance of the joints is insufficient. These results suggest that the anchorage of the longitudinal reinforcement of the slab in the joint’s core area should be improved, and attention should be paid to the short-column stirrup configuration of the SSCJ. These results can provide a research basis for the design of such joints in future applications.
- 通过对2个错层板柱节点试件进行低周往复加载试验, 研究了错层板柱结构错层部位节点的力学性能.分析了错层板柱节点在低周反复荷载下的荷载-位移曲线、节点的延性、耗能能力等性能, 明确了错层板柱节点的工作机理及破坏形式.试验结果表明, 2个错层板柱节点试验构件均呈现典型的短柱脆性剪切破坏, 节点的滞回曲线捏拢现象明显, 耗能能力较弱, 可以看出错层板柱结构的节点抗震能力弱于一般框架结构.根据对试验现象的分析, 建议错层板柱节点中板纵筋应在节点核心区加强锚固, 并且在节点设计时需重点关注错层板柱节点短柱箍筋配置.试验结果可对错层板柱结构节点设计提供研究基础.
