| 中文摘要: |
| 本文针对包括地基基础的框架结构以及不包括地基基础的框架结构基于有限元技术分别进行了动力时程分析，分析结果表明两种计算模型对应的抗震能力存在显著差异。此外，针对包括地基基础的框架结构在不同材料属性地基土层条件下进行了动力时程分析，分析结果表明随着土层弹性模量的增加框架结构的抗震性能变化显著。 |
| 英文摘要: |
| In this paper, based on the finite element method, the dynamic time history analysis is carried out for the frame structure including the foundation and the frame structure which does not include the foundation. The analysis results show that there are sharp differences between the two models of the corresponding seismic capacity. In addition, the dynamic time history analysis is carried out on the foundation frame structure under different soil properties. The results show that the seismic performance of the frame structure changes significantly with the increase of the elastic modulus of the soil layer. |
