［摘要］索支承点支式玻璃幕墙作为柔性非线性张拉结构，有着刚度小、阻尼小、自振频率较低等特性，其在地震和风振作用下的响应不同于一般结构。采用ANSYS软件，计算分析了合肥新桥国际机场航站楼索支承点支式玻璃幕墙的自振特性、地震和风振作用下的响应及玻璃幕墙对主体结构地震响应的影响。分析考虑玻璃幕墙和主体结构的耦合作用，得出可独立分析玻璃幕墙的风振响应，而在地震作用下玻璃幕墙和主体结构之间有着一定的相互影响。本工程索支承点支式玻璃幕墙的设计，在地震和风振作用下是安全可靠的，采用的分析计算方法也可供同类工程参考。

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
