摘要

研究分析了在强烈地震作用下采用刚塑性模型与弹塑性模型计算结构最大塑性位移的差别,结果表明可以利用刚塑性模型来计算结构的最大塑性位移,提出了一种能计算建筑结构在强烈地震作用下最大塑性位移的刚塑性位移谱法,并通过实例把计算结果与弹塑性时程法做了比较,二者虽然具有差别但符合要求,同时还计算绘制了刚塑性反应谱。
In this paper study difference between plastic displacements of structure under strong earthquake calculated using rigid-plastic model and calculated using elastic-plastic model.The results show that rigid-plastic model can be introduced to calculate the max plastic motion under strong earthquake.Motivated by this a rigid-plastic response spectrum is introduced,which provides an easy method to calculate the maximum plastic displacement of structure under strong earthquake.The procedure is formulated using a step by step format followed by an example.Results are compared with refined elastic-plastic time-history analysis and found to be extremely encouraging.
