摘要

首先介绍了多维多点输入地震反应分析的基本原理。进而采用时程分析法对昆明新机场航站楼进行考虑行波效应的多维多点输入地震反应分析,并与一致输入分析结果进行比较,结果显示多维多点输入条件下下部结构的扭转效应有显著增加。由于基础采用隔震设计,行波效应对上部结构带来的影响得到了有效控制。
The principle of multi-support and multi-dimension excitation seismic analysis is introduced.Time-history seismic analysis for the terminal of New Kunming Airport Building considering traveling effect and double direction input is carried out.The results of multi-support and multi-dimension seismic analysis have been compared with the results of single-support and multi-dimension analysis,and the conclusion shows that the torsional effect increases obviously.With the vibration insulation design of the foundation,the superstructure traveling effects are limited.
