结构屈服 meaning in English

yielding of structure

But this method still exists some shortcomings such as : while adopting displacement - control analysis method how to estimate the structural displacement requirement , how to select the horizontal load mode before and after the structure yields , how to considerate the high level mode that have a large effect while it is in the later position , how to considerate the elastic - plastic response spectra correctly . these problems remain to be solved . so this method needs to improved furtherly
但该方法仍存在一些不足，如：分析时采用位移控制的方法时，如何预估结构的最大位移需求；结构屈服前后水平荷载的分布模式如何选取；对结构影响显著但比较靠后的高阶振型如何考虑；如何正确的考虑结构的弹塑性反应谱等问题仍没有得到很好的解决，因此该方法仍需进一步的改进。
