摘　　要：为研究波纹钢板纵向接缝高强度螺栓连接承载力,建立ABAQUS有限元模型,探讨了端距、螺栓预拉力、波形对波纹板连接件承载力的影响.结果表明:为保证板件端部不被剪断,波纹板连接件的端距应不小于3 d 0;当波纹板连接件发生孔壁承压破坏时,承载力随预拉力的增加而增加,承载力计算公式建议按中国平板连接计算公式乘以1.1的增大系数考虑;当发生螺杆剪切破坏时,预拉力对承载力影响较小,波纹板连接件承载力按平板连接计算公式计算.To study the bearing capacity of high strength bolt connection for longitudinal seam of corrugated steel plates(CSPs),finite element models of test specimens were established by ABAQUS software.Influences of end distance,bolt preloading,and waveform of high strength bolt on the bearing capacity of CSP connection were discussed.Results show that the end distance of CSP connectors should be larger than 3 d 0 to avoid the shear fracture of the plate end.When bearing failure at bolt hole occurred,the bearing capacity gradually increased with the increase of bolt preloading.The calculation formula of the bearing capacity of CSP connectors was suggested to be multiplied by the increase factor of 1.1 on the basis of the calculation formula of China for calculating flat plate connectors.When bolt shearing failure occurred,bolt preloading had little effect on bearing capacity,and the calculation formula of the bearing capacity of CSP connectors could be calculated as that of flat plate connectors.
