［摘要］本景觀橋工程通過參數(shù)化設(shè)計(jì)實(shí)現(xiàn)了從建筑方案到結(jié)構(gòu)設(shè)計(jì)及后期施工圖的無縫銜接和高效配合，將不規(guī)則異形橋梁的幾何數(shù)據(jù)有效運(yùn)用于結(jié)構(gòu)建模及分析中，更加平衡性地解決了橋體找形問題。通過力學(xué)分析手段，得到了大跨度鋼桁架橋體承載力、變形、穩(wěn)定性分析和舒適度分析等方面的結(jié)果。此外，利用有限元軟件ANSYS，根據(jù)結(jié)構(gòu)分析得到的桿件內(nèi)力結(jié)果對支座處受力復(fù)雜的管桁架相貫節(jié)點(diǎn)進(jìn)行了有限元分析，并驗(yàn)證了結(jié)構(gòu)方案的合理性和安全性。

Abstract:The landscape bridge project realizes seamless transition and efficient cooperation from architectural design to structural design and late construction drawing design via parametric design. Geometry data of the irregular and heteromorphic bridge was effectively applied to structural modeling and analysis, and the problem of the bridge form-finding was resolved with a more balanceable method. Bearing capacity, deformation, stability analysis and vibration serviceability analysis of the long-span steel truss bridge were obtained by mechanical analysis means. Besides, on the basis of member internal forces in structural analysis, finite element analysis of tubular joint under complex force at supports of the steel tube truss was conducted by ANSYS, the rationality and security of the structural concept were verified as well.
Keywords:long-span; landscape bridge; parametric design; steel structure; finite element analysis
