摘要
通过3个不同轴压比的预应力混凝土扁梁框架内节点试件的低周反复荷载加载试验,对节点的破坏形态、滞回曲线、延性、耗能能力以及刚度退化等抗震性能进行了初步研究,并着重探讨了轴压比对预应力混凝土扁梁框架内节点抗震性能的影响规律。
The pseudo-static test of three inner joints of prestressed concrete flat-beam frame was carried out to research the seismic behavior, such as failure pattern, hysteresis curves, ductility, energy dissipation and rigidity degeneration. And the effect of axial compressive ratio on the seismic behavior of inner joints of prestressed concrete flat-beam frame was determined.
