摘　　要：目前我国组合结构桥梁设计计算方法还不统一,对波形钢腹板PC组合箱梁的设计,不同的设计方法得出不同的计算结果,因此有必要对波形钢腹板的抗剪设计方法进行探讨。对波形钢腹板在抗剪设计中剪应力的计算原理和剪切屈曲的计算理论进行介绍,通过对现有国内外组合梁中钢腹板的设计计算方法比较分析,归纳出了各设计方法间的原理及异同点,以及各个计算方法的适用性,并对现有波形钢腹板抗剪设计计算方法提出相关建议,为波形钢腹板PC组合箱梁的抗剪设计提供参考。Due to the design calculation method of combination structure bridge is not unified in our country and corrugated steel web PC box girder design produce different results with different sets of design method,so it is necessary to discuss the shear design method of corrugated steel web.In this paper,based on the existing research,the shear stress calculation principle of corrugated steel web and the calculation of shear buckling theory are introduced.Through the finite element analysis on the existing domestic and foreign steel web design calculation method of comparative analysis,the principle and the differences and similarities between the various design methods and the applicability of various calculation methods are summed up.Moreover,shear design calculation method about the existing corrugated steel web plate is proposed to provide the reference for the corrugated steel web PC composite box girder shear design t.
