［摘要］以成都金沙遺址博物館中庭屋頂輪輻式雙層索網(wǎng)結(jié)構(gòu)為研究對象，分析了結(jié)構(gòu)在不同荷載分布情況下的靜、動力性能。考慮幾何非線性、材料非線性和幾何初始缺陷，研究了不同矢跨比、預應力度對輪輻式雙層索網(wǎng)結(jié)構(gòu)內(nèi)力、變形以及整體穩(wěn)定性能的影響，結(jié)論對同類工程設計具有參考意義。
［關鍵詞］輪輻式結(jié)構(gòu)；雙層索網(wǎng)結(jié)構(gòu)；臨界預應力值；結(jié)構(gòu)穩(wěn)定性能

Abstract:The spoke rung double layer cable-net structure of the roof of the cortile in Chengdu Jinsha Site Museum, is selected to investigate the structural static and dynamic performance subject to different load cases. Considering geometric and material nonlinearity and initial geometric imperfection, it is studied that the different ratio of rise to span and the prestressed ratio impact on the structural internal force, deformation and overall stability. The conclusion provides some references to design of the other similar spoke structure project.
Keywords:spoke structure; double-layer cable-net structure; critical pre stressing; structural stability performance
