摘　　要：波纹腹板H型钢能以较薄的钢板获得较高的抗剪屈曲能力,从而可以大量节约钢材。但传统的H型钢梁柱刚接节点的构造形式不适用于波纹腹板H型钢梁,为此提出了2种构造形式的波纹腹板H型钢梁柱刚接节点的构造形式。通过静力试验考察这2种节点的承载力以及各截面的内力分布,并对比了试验结果与有限元分析结果及实用设计公式的计算结果,验证了有限元分析的合理性以及实用设计公式的可靠性。使用有限元分析软件ABAQUS对节点进行了参数分析,研究了端板厚度、连接板厚度与波纹断点对节点承载力的影响。Steel H-beams with corrugated webs can provide high shear-buckling resistance with very thin webs,which results in saving of steel.Common beam-to-column rigid connections are not suitable for H-beams with corrugated webs,so 2 types of rigid connections are proposed.In this paper,2 static tests of beam-to-column rigid connections of H-beams with corrugated webs were conducted.And the test results were compared with the results from finite element analysis and the results calculated from the practical design formulas to verify the validity of the results from ABAQUS FEA and reliability from the practical design formulas.Parametric studies were carried out to investigate the bearing capacity of the pinned connection with variations in the thickness of the endplate,the connecting plate and the corrugation at the breaking point.
