摘要: 運河亞運公園體育館由幕墻外圍護鋼結構、內館混凝土框架結構和屋頂空間網架結構組成。 其中幕墻外圍護鋼結構由玻璃幕墻斜交網格鋼結構和疊合金屬幕墻圍合結構組成。 介紹了玻璃幕墻斜交網格鋼結構自方案階段到最終施工圖實施過程中,結構方案的迭代優(yōu)化過程:先對于建筑方案斜交網格的 NURBS 控制曲面,進行了不影響建筑效果的降階處理等優(yōu)化;再通過對于斜交網格典型橫剖面的簡化計算模型受力分析,確定了頂部水平約束、底部固接的支座約束形式,及增大中部區(qū)域抗彎剛度的結構布置原則;最后根據整體結構受力及變形分析,采取了在部分不外露區(qū)域用豎直桿件代替斜交網格,在斜交網格兩端設置通高格構柱,并在斜交網格中間區(qū)域增加一道桁架梁與兩端格構柱形成整體等措施,有效減小了斜交網格豎向壓縮變形和水平外鼓變形,優(yōu)化措施合理有效。

Abstract: Canal Asian Games Park Gymnasium is composed of the facade envelope of steel structure, the concrete framestructure of the inner hall and the roof space truss structure. Facade envelope of steel structure is composed of a glassfacade diagrid steel structure and a metal facade envelope structure. The iterative optimization process of the structuralscheme from the planning stage to the final construction drawing of the glass facade diagrid steel structure was discussed:firstly, for the NURBS control surface of the diagrid of the architectural scheme, optimizations such as order reductionwithout affecting the architectural effect were carried out; then through the force analysis of the simplified computationalmodel of the typical cross section of the diagrid, the top horizontal constraint and the bottom fixed support boundarycondition and the structural arrangement principle to increase the bending rigidity of the middle area were determined;finally, according to the analysis of the whole structure’ s force and deformation, vertical rods were adopted to replace thediagrid in some non-exposed areas. Two latticed columns were set at both ends of the diagrid, and a truss beam was addedin the middle area of the diagrid to form a whole structure with the latticed columns at both ends, which effectively reducesthe vertical compression deformation and horizontal bulging deformation of the diagrid. The optimization measures arereasonable and effective.
