摘要:
本文对两榀中空夹层钢管混凝土柱与钢-混凝土组合梁单边高强螺栓端板连接节点进行了拟动力试验,研究柱截面形式对该新型半刚性组合节点抗震性能的影响,同时考察钢筋桁架-混凝土组合楼板与钢梁在地震作用下的组合效应。试验采用EI Centro波作为拟动力试验的激励输入,获得了地震作用下节点的动力响应和破坏模式,分析了节点的柱端水平荷载-水平位移滞回曲线、动力放大系数、阻尼比、刚度退化规律和累积滞回耗能等抗震性能指标。试验结果表明,方套方或圆套圆中空夹层钢管混凝土柱-组合梁节点具有良好的抗震性能、变形能力和耗能能力,可以应用到实际工程中。
Abstract:
To investigate the dynamic response and failure modes of semi-rigid joints to concrete-filled double skin steel tubular (CFDST) columns and composite beams, pseudo-dynamic tests on two specimens of CFDST column-to-steel-concrete composite beam flush endplate joints with high strength blind bolts were conducted. The influence of column section type to the seismic behavior of the novel joints were studied. And the composite effect between the steel bar truss-concrete composite slab and the steel beam was considered as well. Using EI Centro seismic wave as the simulated seismic excitation input of pseudo-dynamic test, the dynamic response and failure modes of the test specimens were obtained under different acceleration earthquake waves. The seismic performance, including hysteretic behavior, dynamic magnification factor, damping ratio, stiffness degradation and energy dissipation capacity, were analyzed. The test results show that the typed composite joints to square or circular CFDST columns exhibit favorable seismic performance, deformation capacity and energy dissipation. It can be applied to practical engineering.
