［提要］由部分單層橢球體殼和其后的豎直玻璃幕墻組成的采光頂結(jié)構(gòu)，采用點支式玻璃幕墻，結(jié)構(gòu)通透、美觀，視覺效果好。部分單層橢球體殼結(jié)構(gòu)，由于其結(jié)構(gòu)形式復(fù)雜，以往對于該類結(jié)構(gòu)研究較少，對于其力學(xué)性能缺乏了解，因此采用ANSYS軟件對部分橢球體結(jié)構(gòu)進行了各種荷載工況的分析，同時分析了結(jié)構(gòu)的穩(wěn)定性，得到了各種荷載對結(jié)構(gòu)受力性能的影響，為結(jié)構(gòu)設(shè)計提供了依據(jù)。

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
