［提要］由部分单层椭球体壳和其后的竖直玻璃幕墙组成的采光顶结构，采用点支式玻璃幕墙，结构通透、美观，视觉效果好。部分单层椭球体壳结构，由于其结构形式复杂，以往对于该类结构研究较少，对于其力学性能缺乏了解，因此采用ANSYS软件对部分椭球体结构进行了各种荷载工况的分析，同时分析了结构的稳定性，得到了各种荷载对结构受力性能的影响，为结构设计提供了依据。

Design and Analysis of the Lighting Structure at Entrance of Building in Northeast Agricultural University/Feng Ruoqiang,Wu Yue,Shen Shizhao(Space Research Center,Harbin Institute of Technology,Harbin 150090,China)
Abstract:This lighting structure consists of the part singlelayer ellipsoid shell and the vertical glass curtain wall. With dot point supporting glaze and concise steel member, the structure has a good version.The part singlelayer ellipsoid shell is a whole ellipsoid divided by the vertical glass curtain wall plane and the ground plane, and we know little about this part ellipsoid shell.The software ANSYS is used to analyze the static performance of the structure under all sorts of load cases. The stability of the part singlelayer ellipsoid shell is studied,and the key load cases to this structure is got for the design proofs.
Keywords:glass curtain wall；cable structure；glass structure; singlelayer shell
