摘要:

为探索装配式波纹钢结构连接节点的轴压力学行为,以无节点构件作为对照组,以预紧力矩和螺栓间距作为参数变量,开展波纹板轴压试验,研究波纹钢构件螺栓节点受力性能及其对极限承载力的影响,分析构件破坏形态和承载力变化。建立有限元模型,将模拟的构件破坏形态和荷载-位移曲线与试验数据进行对比验证,总结了不同螺栓排数下的构件破坏形态,得到了波纹钢螺栓连接部位荷载-位移特征曲线。结果表明:栓接波纹钢构件破坏形式分为波纹板变形破坏和螺栓孔变形破坏两种; 4排螺栓连接的波纹钢构件与无节点波纹钢构件破坏形态均为波纹板屈曲破坏; 随着预紧力矩的增加,构件滑移荷载和构件承载力峰值不断提高,当超过标准力矩20%时,滑移平台消失; 构件发生螺栓孔变形破坏时,荷载-位移曲线在峰值位置处延性较优; 研究成果可为装配式波纹钢结构连接部位设计优化提供参考。

Abstract:

To explore the axial pressure performance of the joint in assembled corrugated steel structure, taking the non-joint components as the control group, the pre-tightening moment and bolt spacing as the parameter variables, the corrugated steel plate axial compression test was carried out. The stress performance and its influence of the ultimate bearing capacity of the corrugated steel components were studied. The failure forms and bearing capacity variation were analyzed. The finite element model was built, and the simulated failure form and load-displacement curve of the component were compared and verified with the test data. The failure forms of components with different bolt rows were summarized, and the load-displacement characteristic curve of the joint in assembled corrugated steel was obtained. The results show that the failure forms of bolted corrugated steel component include corrugated steel plate failure and bolt row failure. The failure form of corrugated steel members with four rows of bolts or those without joints is corrugated plate buckling failure. Slip load and peak value of bearing capacity increase with the increase of the pre-tightening moment. When the pre-tightening moment exceeds 20% of the standardized moment, the slip platform disappears. The ductility of load-displacement curve is optimized at the peak position when the bolt hole deformation failure occurs. The research findings can provide the reference for the optimizing design of the joint in the assembled corrugated steel structure.
