钢筋混凝土圆环截面偏心受压构件极限强度计算及程序

The Limit Strength Calculation and Program for Circular Section Reinforced Concrete Members under Eccentric Pressures

在文献[1]沿周边均匀配置钢筋的圆形偏心受压构件强度计算的基础上,运用叠加原理推导出内外圆周均匀配置双层钢筋的圆环截面偏心受压构件的极限强度计算公式,所得公式具有一般性,并编写相应的计算程序,程序在数家设计院经多年使用,证明是正确可靠的,可供工程设计应用。

This paper employs superposition theory to deduce formulations for limit strength calculation of eccentrically pressured circular sections with evenly placed double deck reinforcements along inner and outer circles.Works in this paper are based upon former works in strength theory of evenly reinforced circular sections under eccentric pressure.These formulations were attested to be accurate enough and sufficient for engineering applications by incorporating into a computer program that has been used by several design institutes for many years..
