| 摘 要： | 介绍按容许应力法计算普通钢筋混凝土直接求钢筋面积的方法.按公式直接求算钢筋面积,对大偏心受力构件不需在每一具体计算过程中去解一元三次方程,因而简单便捷.这种方法可应用于矩形截面、箱形截面和T形截面,可以配受压钢筋.对计算方法的优化是设计过程的合理化,在优化电算程序方面也将会有一定的意义.

| Abstract: | This article introduces the method for calculating the cross-sectional areas of reinforcement. The calculation is based on allowable stresses and corresponding formulae which avoids solving the cubic equations for elements with large eccentricities in the process of computation and optimizes the design process. The proposed method can be applied to calculate the cross-sectional areas of compressive reinforcements for rectangular, box-shaped and T-shaped sections. Rationalization resulted from optimization helps to optimize the programs of computers. |
