摘要
总结了影响钢筋混凝土受弯构件等效塑性铰区长度的主要因素 ,建立了以临界截面到反弯点的距离z和剪应力密度r为参数的等效塑性铰区长度计算公式 。
This paper summarizes the dominant factors that affect the length of equivalent plastic hinge of reinforced concrete bending structural members,and gives and equation with which to calculate the length of plastic hinge based on the distance between critical section and inflection point Z and the shear stress density r as the parameters.At the same time,it affords the reference for the plastic design of reinforced concrete indeterminate structure.
