中文摘要：

通过3个钢纤维局部增强框架边节点的低周反复加载试验，探讨了柱端轴压比对钢纤维高强混凝土框架边节点抗震性能的影响。结果表明：随着柱端轴压比的增加，其对节点核心区混凝土的约束作用逐渐增大，减缓了抗剪承载力和刚度的退化，限制了节点核心区剪切变形，提高了节点核心区的抗剪承载力、延性和耗能能力。

英文摘要：

By the experimental investigation and finite element analysis of the three steel fiber reinforced high-strength concrete frame exterior joint under the low cycle loading, discussed the influence of axial compressive ratio on seismic capacity of the joint.The result shows that, the increase of the axial compressive ratio enhances the restriction role to the joint core area concrete, slows down the degeneration degree of shearing-resistance capacity and rigidity, limits the shearing deformation of the joint core area, enhances the shearing-resistance capacity of the core area, the joint ductility and the energy dissipation capacity.
