摘要
本文从砼内部微裂缝产生与发展的机理分析了钢筋砼平板在双向拉－压平面应力作用下影响砼受压软化的主要参数；分析了轻骨料砼受压软化性能低于普通砼的作用机理．文中对此进行了实验分析与论证，介绍了双轴拉－压的简化试验装置．通过试验分析，分别提出了普通钢筋砼和钢筋轻骨料砼的软化系数的计算公式．
In this paper,some main parameters which influence the softing property.due to micro-crackappearing and developing of the reinforced concrete and reinforced lightweight aggregate concreteplate are analyzed.And a simplified test set is introduced.Based on test results,formulas forcalculating softing coefficient of common concrete c lightweight aggregate concrete L are given.Itis finded that the value of c is less then L
