型钢混凝土斜梁-柱边节点抗震性能试验研究
Experimental study on seismic behavior of SRC leaning beam-column exterior joints
摘要
Abstract
The leaning beam-column exterior joints can be formed because of the large-scale SRC nuclear power plant having different heights.The quasi-static tests of three specimens with different slope angles in 1/4 scale of prototype model were carried out to study the mechanical characteristics,failure mode,hysteretic performance,energy dissipation,bearing capacity and stiffness degradation of this kind of leaning beam-column exterior joints.The results show that:the dominant failure mode of three specimens is plastic failure at beam ends that can meet the design requirements.The failure mode of SRC leaning beam-column exterior joints is similar to orthogonal beam-column joints.Because of the slope angle,the core shape of joints changes from rectangle to parallelogram,and the internal force transfer of specimens is more complex.With the increase of the slope angle,beam cracks at the end are more wider,and bearing capacity and energy dissipation are more lower,but the effect of the shear deformation of core area with different slope angles is not obvious.It suggests the slope angle should not be beyond 10°.关键词
