摘　　要：外包钢板组合槽形梁结合了预应力混凝土槽形梁和波形钢腹板组合槽形梁的优点,表现出良好的弯曲工作性能,具有较好的发展前景。为分析外包钢板组合槽形梁的挠度计算方法,首先推导出集中荷载和均布荷载作用下梁体剪切挠度和总挠度的计算公式;然后将理论值与试验测试值和ABAQUS模拟值进行对比,证明推导的挠度计算公式具有较好的精确性;最后以梁体腹板高度、腹板厚度和腹板形状为分析指标,研究不同参数对剪切挠度和总挠度的影响,并基于影响分析对推导的剪切挠度公式进行修正及验证。The composite trough beam wrapped with steel plate(CTS)combines the advantages of prestressed concrete trough beam and composite trough beam with corrugated steel web,which shows good bending performance,and has a good development prospect.In order to analyze the displacement calculation method of CTS,firstly the calculation formulas of shear displacement and total displacement under concentrated loads and uniformly distributed loads were deduced.Then the theoretical results were compared with the experimental values and the ABAQUS simulation values.The comparison results show that the displacement calculation formulas have good accuracy.Finally,the web height,web thickness and web shape were taken as analysis parameters,and the effects of these parameters on shear displacement and total displacement were studied.Based on the effects analysis,the shear displacement formulas were modified and verified.
