［摘要］索支承點支式玻璃幕墻作為柔性非線性張拉結構，有著剛度小、阻尼小、自振頻率較低等特性，其在地震和風振作用下的響應不同于一般結構。采用ANSYS軟件，計算分析了合肥新橋國際機場航站樓索支承點支式玻璃幕墻的自振特性、地震和風振作用下的響應及玻璃幕墻對主體結構地震響應的影響。分析考慮玻璃幕墻和主體結構的耦合作用，得出可獨立分析玻璃幕墻的風振響應，而在地震作用下玻璃幕墻和主體結構之間有著一定的相互影響。本工程索支承點支式玻璃幕墻的設計，在地震和風振作用下是安全可靠的，采用的分析計算方法也可供同類工程參考。

Abstract:The cable-supported point-supported glass curtain wall is flexible nonlinear tension structure with characteristics of small rigidity, small damping and low natural vibration frequency, and its responses under earthquake and wind vibration are different from those of the general structure. The natural vibration characteristic and the response under earthquake and wind vibration of the cable-supported point-supported glass curtain wall of Hefei Xinqiao International Airport Terminal were calculated and analyzed by using the finite element software ANSYS. The glass curtain wall′s effect on the seismic response of the main structure was also analyzed. The analysis considers the coupling effect of the glass curtain wall and the main structure, and concludes that the wind vibration response of the glass curtain wall can be independently analyzed, and there is a certain mutual influence between the glass curtain wall and the main structure under the action of earthquake. The design of the cable-supported point-supported glass curtain wall in this project is safe and reliable under the action of earthquake and wind vibration. The proposed calculation and analysis methods can also become the references to the similar projects.
Keywords:Hefei Xinqiao International Airport terminal building; glass curtain wall; cable net support; seismic response; wind vibration response
