| 摘 要： | 本文以基础隔震体系为研究对象,利用ANSYS软件建立了三维有限元模型,讨论了考虑土-结构相互作用的基础隔震体系动力特性,并研究了隔震层和相互作用对体系动力特性的影响因素,以揭示土-基础隔震体系相互作用机理。分析结果表明,考虑相互作用和基础隔震后,结构体系的自振周期延长。改变土体的特性和隔震层水平、竖向刚度,体系的动力特性也会随之改变。

| Abstract: | In this paper, the 3-D model of base-isolated building systems considering Soil-Structure Interaction is set up by ANSYS. In order to search how isolated layer and soil-structure interaction influence dynamic performances of base-isolated systems and bring to light interactive mechanism of soil-base-isolated system, dynamic performance of base-isolated building systems are calculated with varying horizontal rigidity and vertical rigidity of isolated layer, soil dynamic elastic modulus, layered soil depth as well as soil property. Results demonstrate that isolated base and Soil-Structure dynamic interaction effectively prolong the period of the system. The dynamic performance is changed by the characteristics of the soil and horizontal rigidity and vertical rigidity of isolated layer. |
