摘　　要：由于滑移效应的影响 ,采用栓钉剪力连接件的钢 压型钢板混凝土组合梁的刚度和抗弯承载力均有所降低。本文在折减刚度法的基础上 ,建立了适用于钢 压型钢板混凝土组合梁的修正折减刚度计算公式 ,并进一步建立了考虑滑移效应影响的弹性抗弯承载力计算公式。Methods for analysis of composite?steel beams with profiled sheet are proposed in the paper.The beam is connected with stud shear connectors.Elastic stiffness and flexural capacity of the beam are less than that with traditional connection due to the slip effect.The reduced stiffness method is developed by the authors in a previous study,it is modified and extended to analyze the stiffness of the beam.Another analytical method is also proposed to calculate the flexural capacity of the beam with consideration of the slip effect.The results are in good agreement with that of the experimental results.
