一、前言钢筋混凝土构件的断面尺寸及钢筋量是由加载所产生的弯矩、剪力等所决定的。所以一旦算出弯矩、剪力,接下就是选择构件断面尺寸和计算钢筋量了。这一工作一般都是按钢筋混凝土结构书中用查表法进行的。本文采用图解的办法来计算。图解法的主要工具是线解图(编者:列线图)。本文的线解图是按300号混凝土,容许应力[σ_c]=100kg/cm~2,钢筋16锰,容许应力[σ_s]=1800kg/cm~2,钢筋与混凝土的弹性模量比n=10
First, the preface Reinforced concrete members of the cross-sectional size and the amount of steel is loaded by the bending moment, shear and other decisions. So once you calculate the bending moment, shear force, the next is to select the component section size and calculate the amount of steel. This work is generally carried out according to the book list method in the book of reinforced concrete structure. This article uses a graphical approach to calculate. The main tool of the graphical method is the line solution diagram (Editor: nomogram). The line diagram of this paper is based on 300 concrete, allowable stress [σ_c] = 100kg / cm ~ 2, steel 16 manganese, allowable stress [σ_s] = 1800kg / cm ~ 2, elastic modulus ratio of steel and concrete n = 10
