摘要
为研究冷弯十字型连接件连接的钢板组合剪力墙结构的滞回性能。利用ABAQUS有限元分析软件建立14个模型,分析连接件梁端螺栓直径、与螺栓连接的钢板摩擦面抗滑移系数、钢梁跨高比对结构滞回性能的影响。结果表明:连接件梁端螺栓直径增大,结构承载能力、延性、耗能性能略有提升,较大的螺栓直径有利于连接件末端梁翼缘塑性铰的形成,建议螺栓直径取22~27 mm;改变抗滑移系数对承载能力影响不大,取0.3~0.4,延性性能、耗能能力更好;随跨高比的增大,结构初始刚度、承载能力、延性、耗能能力逐渐提高,建议跨高比取4.5~6.6。
In order to study the hysteretic behavior of steel plate composite shear wall structure connected with cross cold-formed connectors.Fourteen models are established by using ABAQUS finite element analysis software to analyze the effects of bolt diameter at the beam end of the connector,anti-slip coefficient of steel plate friction surface connected with the bolt and span height ratio of steel beam on the hysteretic performance of the structure.The results show that with the increase of the bolt diameter at the beam end of the connector,the bearing capacity,ductility and energy dissipation performance of the structure are slightly improved.A larger bolt diameter is conducive to the formation of plastic hinge at the beam flange at the end of the connector.It is suggested that the bolt diameter should be 22~27 mm;changing the anti-slip system has little effect on the bearing capacity,taking 0.3~0.4,the ductility and energy dissipation capacity are better.With the increase of span height ratio,the initial stiffness,bearing capacity,ductility and energy dissipation capacity of the structure gradually increase.It is suggested that the span height ratio should be 4.5~6.6.
