本文(上)概述:本文所介绍的简易优化设计法的特点是:先根据钢筋和混凝土的价格以及力学方面所要求的条件,设计出最经济的截面尺度(不是习用的假设的尺度),然后计算其配筋。上篇介绍了F.J.计算式的推导和在受弯构件单筋矩形梁、T形截面梁计算经济截面上的应用,并附有算例。以本法计算的设计成果比用常规方法的设计成果可节省投资10%~25%。
This article (on) Overview: The simplified optimization design method described in this article is characterized by the most economical design of the cross-section scale (not the conventional assumption of the scale) according to the price of steel and concrete and the mechanical requirements, and then Calculate the reinforcement. The last chapter introduces the derivation of F.J. calculation formula and its application to the calculation of economic section of single-beam rectangular beam and T-section beam with flexural members, with examples. The design results calculated by this method can save 10% ~ 25% of the investment than the design results by conventional methods.
