延性是混凝土构件的一项重要特性 ,延性系数是构件延性的度量 ,由于沿周边均匀配筋环形截面偏心受压构件受力计算的特殊性 ,至今没有一个较精确的计算公式。本文根据沿周边均匀配筋环形截面偏心受压构件的工作特点 ,采用常用应力应变关系和基本假设 ,提出了其延性系数的计算方法。
Ductility is an important characteristic of concrete members. Ductility coefficient is a measure of ductility of members. So far, there is no accurate calculation formula because of the particularity of stress calculation of eccentric compression member with annular reinforcement with uniform reinforcement around it. In this paper, according to the working characteristics of eccentric compression members with annular reinforcement uniformly distributed along the periphery, the calculation method of ductility coefficient is proposed based on the common stress-strain relationship and the basic assumptions.
