摘要
本文提出了考虑混凝土“应力－应变”关系下降段和纵筋锚固滑移影响的钢筋混凝土异型（Ｌ、＋、Ｔ）柱非线性变形计算方法，用该方法计算的“Ｍ－φ”曲线与试验结果符合较好。
In this paper, the calculating method of nonlinear deformation on R.C. L,+,T shaped columns is presented, while the fall path of the stress strain relation of concret and the sliding of longitudinal reinforcement anchoring are all considered. The “M φ” curves calculated by this method agree well with experimental results.
