摘　　要：混凝土结构设计规范给出了矩形截面正截面设计计算方法,提出α1和β1系数并给出相应的取值,规范对于任意截面的计算仅在附录中给出基本原理,在非矩形截面设计时,设计人员常进行简化并参照矩形截面计算,并采用规范所给出的α1和β1等系数取值。非矩形截面相应的α1和β1等计算系数与矩形截面应当有较大差异。本文对正截面设计中α1和β1等系数进行分析研究,并提出非矩形四边形梁等其它形式截面采用α1和β1等系数的计算方法。The design of concrete structures is given rectangular cross section is section design calculation methods, and make of α1 β1 in coefficient and the corresponding values and norms for the calculation of arbitrary cross-section only the basic principles given in the appendix,in a non-rectangular cross-section designdesigners often simplify and reference to the rectangular cress section calculation, and α β1, and other values of coefficients given by the specification. Coefficient of non-rectangular cross-section corresponding α1 β1,such as the coefficient of rectangular cross section should be quite different. In this paper the design of the normal section to calculate the coefficient of α1, β1 analysis, and proposed other forms of non-rectangular quadrilateral beam cross-section using the method of calculation of the α1 ,βl coefficient.
