(北京市建筑設(shè)計研究院,北京 100045)[摘要]首先介紹了多維多點輸入地震反應(yīng)分析的基本原理。進而采用時程分析法對昆明新機場航站樓進行考慮行波效應(yīng)的多維多點輸入地震反應(yīng)分析,并與一致輸入分析結(jié)果進行比較,結(jié)果顯示多維多點輸入條件下下部結(jié)構(gòu)的扭轉(zhuǎn)效應(yīng)有顯著增加。由于基礎(chǔ)采用隔震設(shè)計,行波效應(yīng)對上部結(jié)構(gòu)帶來的影響得到了有效控制。[關(guān)鍵詞]航站樓;多維多點;行波效應(yīng);時程分析方法;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*云南省社會發(fā)展科技計劃—社會事業(yè)發(fā)展專項。項目編號2008CA007。作者簡介:束偉農(nóng),碩士,教授級高工,Email:Shuweinong2@vip.sina.com。參考文獻[1]屈鐵軍,王前信. 多點輸入地震反應(yīng)分析研究的進展[J].世界地震工程,1993(1):30-36.[2]林家浩,李建俊,張文首.大跨度結(jié)構(gòu)考慮行波效應(yīng)時非平穩(wěn)隨機地震響應(yīng)[J].固體力學(xué)學(xué)報,1996,17(1):65-68.[3]SU LIANG, DONG SHILIN, SHIRO KATO.
