| 摘 要： | 传统的抗震设计都是基于刚性地基的假设,然而在实际中,地基会发生变形致使上部结构的动力特性改变。本文结合工程实例,建立非线性有限元桩-土模型和土弹簧桩-土模型桩,用ANSYS建立了非线性有限元实体桩和土弹簧桩的房屋结构模型研究地震作用下结构在考虑桩-土-结构动力相互作用时的动力特性及其地震响应。

THE EARTHQUAKE ANALYSIS OF HIGH BUILDING CONSIDERING THE INTERACTION OF PILE-SOILSTRUCTURE |
| |
| Abstract: | In traditional aseismatic analysis of structures, the foundation soil is considered to be rigid, in fact, the feedback from the inertia force of the upper structure will alter the movement of foundation. This study combines with specific project, The pile-soil models are established use the non-linear finite element method and soil spring method, then establish the non-linear finite element method and soil spring method of building mode using the ANSYS soft to research the dynamic characteristics of the model and the near-field earthquakes resposes of structure that considers the effect of pile-soil-structure interaction. |
