摘要
通过5个板柱结构中柱节点的水平低周反复荷载试验,研究了中柱节点的延性、滞回特性、耗能能力和破坏形态。实验结果表明,水平荷载作用下中柱节点主要有弯曲破坏和冲切破坏2种破坏形态,板中钢筋的配筋率是影响节点破坏形态的主要因素之一,板柱结构中柱节点的抗震性能要比框架结构的梁柱节点差。
Based on five specimen tests of interior slab-column connections under low-cycle reversed loads, hysteretic behaviors, ductility, and energy dissipation of interior slab-column connections are studied. Test results show that the main.failure modes of interior connections are flexural failure and punching failure. Steel ratio of slab is one of the main factors affecting the failure mode of slab-column connections. The seismic performance of interior slabcolumn connections is less than that of beam-column connections.
