| 摘 要： | 基于改进塑性铰法,讨论了构件的计算单元,二阶效应,截面的塑性扩展、构件残余应力、初始几何缺陷等各种非线性因素的处理方法,采用改进塑性铰法可以保证结构较高的计算精度,比较真实地反映结构在荷载作用下的内力和变形状态,可用于工程分析和设计。

| Abstract: | Based upon refined plastic-hinge method treatment methods of calculation unit, second-order effects, plastic growth of cross-section, residual stress, primary geometric defects and other nonlinear factors are discussed. Author points out that the uses of refined plastic-hlnge method ensure the calculation accuracy of structure, which actually reflects the internal force and deformation status of structure under load actions. |
