摘要
通过对梁柱节点附加阻尼器和现浇混凝土框架结构梁柱节点进行进行低周反复荷载试验,研究其滞回曲线、骨架曲线、刚度退化曲线、耗能能力曲线及残余变形等抗震性能。结果表明:附加阻尼器的预应力装配式框架结构节点在变形恢复能力、耗能等性能优于现浇框架节点,附加适当的阻尼耗能措施将在预制装配构件中得到肯定,并将得到广泛应用。
Through additional damper beam-column joints and pouring concrete frame beam-column node low cyclic loading test, the seismic behavior of hysteresis curves, skeleton curves, energy dissipation ,stiffness degradation curve curves and residual deformation were studied. The results show that precast concrete frame structure nodes additional damper deformation resilience, energy and other properties are better than cast frame joints, additional appropriate damping energy measures would be certainly affirmed in prefabricated members, and will be widely applied.
