摘要
对高层简体结构进行弹塑性地震反应分析，基本未知量很多，基本参数的确定也较困难。本文采用广义有限条法对筒体结构作弹塑性地震反应分析，以构件为基本单元，计算参数和恢复力曲线容易确定。本文综合应用和发展了有限元法和有限条法的优点，计算精度和有限元法相当。
A generalized finite strip method is proposed in this paper. Using structural member as analysis element the fundamental parameters and hysteresis loops can be determined easily. It synthesizes the advantages of finite element method and finite stripmethod. The accuracy of the method is commensurate with finite element method'
