摘　　要：采用有限元分析方法,建立不同波纹尺寸H型钢梁柱刚性连接节点域有限元模型。通过计算对比,分析梁波纹尺寸不同时,节点域的屈曲特征值、破坏形态、最大变形和Von Mises应力值的差异,并根据Von Mises应力得出节点域的危险区域。分析结果表明,波纹尺寸较小的波纹腹板H型钢梁柱刚性连接节点域整体上具有承载力略高、最大变形较小和Von Mises应力较小的优势,对波纹腹板梁在多高层框架中的应用有一定的参考价值。With the finite element analysis method,different corrugation sizes of H-shaped steel beam-to-column rigid connection panel zone models are established. By calculation and comparison,the diffience of the buckling eigenvalue,failure modes,maximum deformation and Von Mises stress values of the panel zone is analysed when the sizes of corrugation are changed. And according to the Von Mises stress,the danger zone of the panel zone is obtained. The results show that H-shaped steel beam-to-column rigid connection panel zone with smaller corrugation size has the advantages of higher bearing capacity,smaller maximum deformation and Von Mises stress. It has a certain reference value to the application of corrugated web beam in high-rise framework.
