摘要
变截面构件的弯曲变形是实际构件常见变形之一，现行钢筋混凝土设计规范提供的和实际设计计算应用的剪应力计算公式未考虑截面变化的影响，有较大的误差。本文用材料力学方法推出考虑变截面影响的剪应力计算公式，以便在实际设计计算应用。
Curved deformation of member of varying section is one of usual defor-mations in actual member,The effect of section changing transformation is not includedin shear stress calculation formula in the present concret design standard.That leadsmajor errors.This paper concludes a shear stress calculation formula considering effectof section changing based on the principle material mechanics.
