波形钢板具有褶皱效应，不承担轴向力和弯矩作用，其有效弹性模量低于材料弹性模量。文中推导了波形钢板的有效弹性模量计算公式，提出波形钢腹板组合梁的抗弯计算方法，且依托某一座波形钢腹板连续组合箱梁桥，建立有限元模型，进行了应力、抗裂性、承载力等抗弯性能分析。

Corrugated steel webs have crinkled effect,and cannot bear the axial force and bending mo-ment,which make its effective elastic modulus smaller than that of the material.The computational formula is deduced of effective elastic modulus of corrugated steel webs,and the calculation method is put forward of corrugated steel webs with composite beams.Based on a continuous composite box-girder bridge with corru-gated steel webs,a finite element model is built,and the bending performance is analyzed,including normal tensile stress,normal compressive stress,crack resistance and bearing capacity.
