摘　　要：本文从梁横力弯曲的挠曲线微分方程入手，详细地分析了横力弯曲时正应力与挠度的计算方法，并结合工程实践，给出了工字形、箱形截面的薄壁短梁相应的简明且实用的计算公式，讨论了剪力的影响程度．Base on the deferential equation of deflection curve in transverse bending, the method of calculating the normal stress and deflection was analyZed in this paper. The concise and practical formulas for short thin wall beam, either I section or box section, were derived for engineering practice. The effect of shear force Was also discussed.
