摘要
针对地震动的多维性 ,建立了结构在多维地震动下的动力平衡方程 ,并引用Prager随动强化准则模拟了结构的开裂与屈服后的性能 ,得出了结构在考虑多维地震作用下和只考虑单向水平地震作用下计算结果的一些差异 ,而且使得计算过程也大为简化
Based on the characteristics of multi dimensional earthquake ground motions,the equilibrium equations for multi dimensional earthquake ground motions of structure are established.Prager criterion is quoted to simulate the cracking and yielding behavior,the calculation discrepancies of structure between considering multi dimensional earthquake and considering single dimensional earthquake are found,and calculating course is greatly simplified in this paper.
