文雙玲 侯兆欣 楊建平 王 云 張衛(wèi)航 (冶金工業(yè)部建筑研究總院 北京 100088)曾凡生 楊 琦 王世斌 (中國建筑西北設(shè)計研究院 西安 710003)[提要] 西安國際展覽中心鋼結(jié)構(gòu)采用直接焊接的鋼管結(jié)構(gòu),包括帶斜拉索的大跨度空間桁架、裝飾網(wǎng)殼和門廳抗風桁架等幾部分。各樓層的梁板柱(包括懸掛斜拉索的立柱)為鋼筋混凝土結(jié)構(gòu)。由于結(jié)構(gòu)形式復(fù)雜,結(jié)構(gòu)分析采用整體空間模型,并采用了較為合理的相貫節(jié)點和銷釘連接形式,可供其他工程參考。
[關(guān)鍵詞] 展覽建筑 鋼管 空間桁架An intersecting welding space structure of steel pipe is used for the steel construction of Xi'an International Exhibition Centre, which consists of the long-span spatial truss with stayed-cables, the decorative latticed shell and lobby wind resisting truss etc. The complicated structure incorporates a reinforced concrete structure and a spatial steel structure with a stayed-cable structure. The key to the project design is coordinating the internal forces of the combined structure into its deformations. A monolithic structural analysis is conducted on the whole building space model using a program SAP93.
