摘要
基于双线性系统的最大位移与弹性系统的最大位移关系,提出了一种适于隔震桥梁设计的非迭代计算方法,对一座5跨连续隔震桥梁用3个不同参数的模型进行了计算,并与等效线性化计算结果及时程分析结果进行了比较,结果表明,该方法偏于安全,能有效地计算出隔震桥梁位移反应的最大值,且应用简便,易于被设计工程师接受。
A non-iterative designing method for the isolated bridge is put forward based on the relation of the displacement between the bilinear system and the elastic system. The 5 span continuous isolated bridge is caculuted with three models of different parameters. Compared with the results of the equivalent elastic method and the timehistory method, the method of this paper is safe and can acquire the maximum displacement of the isolated bridge efficiently. The method is simple and can be accepted by the design engineer easily.
