摘要
为研究装配式混凝土框架结构的抗震性能,对4个采用大直径灌浆套筒的足尺装配式混凝土框架结构梁-板-柱节点试件进行低周反复加载试验,对装配式混凝土框架结构中节点、边节点及其现浇对比节点的破坏形态、滞回曲线、位移延性、刚度退化、耗能能力等进行了研究。结果表明,此类装配式混凝土框架结构中节点、边节点与其现浇对比节点均为梁端塑性铰破坏,抗震性能较好。
In order to study the seismic behavior of prefabricated concrete frame structure,4 full-scale prefabricated concrete beam-slab-column joints with grouting sleeves of large diameter were investigated under low-cycle reversed loading test. The failure modes,hysteresis curves,displacement ductility,stiffness degradation and energy dissipation capacity of the prefabricated concrete frame interior joints,exterior joints and the comparison cast-in-place joints were studied. The results show that all the joints achieve the failure mechanism of beam plastic hinge and have equivalent seismic behavior when comparing with cast-in-place joints.
