摘要
为 了研究宽柱双梁节点在低周往复荷载作用下的受力机理、抗剪承载力及抗震性能,文章建立5 个宽柱双 梁有限元模型.分析节点区的纵梁、梁柱抗弯强度比值、轴压比、核心区配箍率等因素.结果表明,纵梁、梁柱抗弯强 度比值对节点核心抗剪承载力的影响较大,空间节点较平面节点受力性能分析更加复杂,空间节点的延性和平面节 点相比存在明显不足,这是由于空间节点受双向荷载的作用,核心区更容易破坏.该文与文献[7]中EBCJ -1模型作对 比,试验骨架曲线与模拟骨架曲线吻合度较好.
In order to study the joint with wide column and double beams in weeks under reciprocating load bearing mechanism,the shear bearing capacity and seismic performance,this article uses 5 joint with wide column and double beams finite element model to analyse longitudinal beam,beam column node area bending strength ratio, axial compression ratio, core area stirrup ratio and other factors. Results show that the longitudinal beam,beam bending strength ratio of core shear bearing capacity is larger,the influence of the planar space node force performance analysis of more complex, ductility and plane of a space node than obvious deficiencies, it is because of the space node under bi -directional load effect, core damage more easily. This article with the literature [7] compare EBCJ - 1 model,test simulated skeleton curves and skeleton curve alignment is good.
