摘要:
通过对一个钢筋混凝土框架中柱空间梁柱节点和一个带现浇楼板空间节点在平面内施加低周反复荷载以及对一个带板空间节点在斜向施加低周反复荷载,深入研究了空间节点在平面内加载和斜向加载下的破坏形态,滞回性能等抗震性能。试验结果表明:在正向弯矩作用下,带板试件梁端承载力略有提高,延性发展直至纵筋拉断;在负向弯矩作用下,带板试件由于板筋参与工作承载力提高2倍以上,变形能力受受压区混凝土破坏控制,与无板试件相当;带板试件在斜向荷载作用下由于相邻梁上作用弯矩相反,减少了板筋参与工作范围,承载力略低。
Abstract:
Experiments on reinforced concrete frame spatial beam-slab-column joints are conducted under low cyclic repeated loadings.Failure modes,hysteresis curves and other seismic performance of the spatial joints are investigated.Experiment results show that under the action of the positive moment,the bearing capacity of beam-slab-column joint is increased just a little and the displacment has developped fully until the beam steel reached its tension failure state;under the action of the negative moment,the bearing capacity of beam-slab-column joints have been increased by more than 2 times for the participation effect of the slab steel and the deformability is controlled by the damage of the compression area concrete,which is familiar with the beam-column joint,the bearing capacity of the joint with slab under the action of oblique direction loading is a little lower than the strength of the joint which is loaded in-plane.
