摘要

分析发现通过迭代方法可以获得满足一定精度要求的结构弹塑性阶段能力曲线,该曲线与需求谱曲线相交,即可得到地震作用下结构进入弹塑性阶段的性能,方法所能达到的精度由迭代次数决定。
It makes an inelastic static analysis on the structure,finds out that certain precision plastic phase capacity curve can be attained through the iterative structure.Once this curve is intersected with demand spectrum curve,properties of structural plastic stage could be reached under the earthquake condition.The accuracy of this method is decided by the number of iterations.
