摘要
运用有限元方法建立桩-土-结构的动力相互作用的分析模型,对水平地震作用下考虑和不考虑土—结构相互作用的高层建筑进行二维弹塑性模拟和对比分析。通过对地震反应峰值变化的比较,研究考虑相互作用后的上部结构反应规律,并探讨上部结构刚度变化对相互作用的影响。
In this article, finite element method is adopted to design analytic model for dynamic interaction of pile-soil-structure system and to carry out elastoplastieity simulation and contrastive analysis on high-rise with and without consideration of soil-structure interaction under horizontal seismic action. Through comparison among peak values of seismic responses, reaction law of superstructure with interaction are researched and impact of rigidity change of superstructure on the interaction is discussed.
