摘要
针对软化结构的负刚度问题,提出了一种多维虚加弹簧法.该方法物理概念直观,编程简明,可以用于求解多点加载下控制荷载比例的结构加卸载全过程数值分析.运用该方法对多个结构进行了解算,结果表明该方法可行并具有良好的收敛性.
The multi-assumed-spring method is developed to solve the negative stiffness problem of softening structures. This scheme has direct physical sense and can be programmed concisely. It is applicable in the numerical analysis of a structure subject to multi loads for the whole loading and unloading processes with controlled load proportion. A few cases are studied with this approach, which shows that it has good feasibility and convergence.
