(北京市建筑设计研究院,北京 100045)[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。[关键词]航站楼;多维多点;行波效应;时程分析方法;隔震Multi-support and multi\|dimension excitation seismic analysis on New Kunming Airport BuildingShu Weinong, Li Huafeng, Bu Longgui, Zhu Zhongyi, Gan Ming, Ke Changhua, Huang Jia, Qi Kai, Wang Yi(Beijing Institute of Architectural Design, Beijing 100045, China)Abstract: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.Keywords:airport building; multi-support and multi-dimension; traveling effect; time-history seismic analysis; vibration insulation*云南省社会发展科技计划—社会事业发展专项。项目编号2008CA007。作者简介:束伟农,硕士,教授级高工,Email:Shuweinong2@vip.sina.com。参考文献[1]屈铁军,王前信. 多点输入地震反应分析研究的进展[J].世界地震工程,1993(1):30-36.[2]林家浩,李建俊,张文首.大跨度结构考虑行波效应时非平稳随机地震响应[J].固体力学学报,1996,17(1):65-68.[3]SU LIANG, DONG SHILIN, SHIRO KATO.
