为准确计算波形钢腹板混凝土组合梁的挠度，推导了考虑剪切变形影响的波形钢腹板混凝土组合梁的挠曲线初参数方程。首先分析了波形钢腹板混凝土组合梁截面上剪应力的分布特点，得到了腹板剪应力的简化计算公式；然后推导了其挠曲线的初参数方程，提出了组合梁挠度的计算方法，进而对承受跨中集中荷载、两点对称荷载和均布荷载等3种典型荷载作用下的波形钢腹板混凝土组合梁的挠度进行分析，并将其结果与试验实测值、有限元结果进行比较，验证了文中理论方法的准确性和适用性；最后利用文中理论方法和有限元方法分析了跨高比和宽高比对波形钢腹板混凝土组合梁剪切变形的影响，并给出了波形钢腹板混凝土组合梁挠度计算是否需要考虑剪切变形影响的跨高比界限建议值。

In order to accurately calculate the deflection of concrete composite girder with corrugated steel webs , the initial parameter equations of deflection curve of the girder , which take into consideration the influence of shear deformation, were deduced.In the investigation, first, the distribution characteristics of the shear stress in girder sections were analyzed , and a simplified formula for calculating the shear stress in webs was obtained .Then, the initial parameter equations of deflection curve of the girder were deduced , and a deflection calculation method was put forward.Moreover, the deflection of concrete composite girder with corrugated steel webs under three typical loads, namely the midspan-concentrated load, the symmetrical load and the uniformly-distributed load, was ana-lyzed by using the proposed method , and the results were compared with those obtained by experiments and finite element analysis , finding that the proposed theoretical method is accurate and applicable .Finally, by using the proposed method and the finite element method , the influences of depth-to-span ratio and aspect ratio on the shear deformation of the composite girder were explored , and a limit value of depth-to-span ratio was suggested for deter-mining whether the influence of shear deformation should be considered during the deflection calculation .
