摘　　要：介绍了一种基于VB语言的箱形梁弯曲、扭转组合变形强度分析程序的开发。完成了梁弯曲初等理论假定下梁体的纯弯曲受力分析;同时基于薄膜比拟法对矩形板条组合开口截面和单室、多室闭口截面进行了自由刚性扭转强度分析;最后按照第四强度理论对截面进行了等效应力计算。This paper introduces a method based on VB language box girder bending and torsional strength combined deformation analysis program development. It completed the elementary theory of beam bending beam under the assumption of pure bending stress analysis; same simulation method based on thin-film combinations rectangular slats open section and a single room, multi-room cross- section of the free rigid closed torsional strength analysis; final in accordance with article strength theory section were calculated equivalent stress.
