［摘要］貴州省亞高原體育訓(xùn)練基地攀巖館屋蓋造型為兩個有高差的半邊橢圓球，是國內(nèi)外場館建筑中較早采用帶高差兩個半邊橢圓球屋蓋的場館；場館采用橢球形凱威特K6單層網(wǎng)殼結(jié)構(gòu)+立體拱架+豎向平面交叉桁架組合的雜交結(jié)構(gòu)體系，下部為鋼筋混凝土框架-剪力墻結(jié)構(gòu)。主要介紹了鋼屋蓋的結(jié)構(gòu)選型及結(jié)構(gòu)布置。采用多模型的計算分析方法，對結(jié)構(gòu)進(jìn)行設(shè)計分析并驗算鋼屋蓋的穩(wěn)定性；對復(fù)雜相貫節(jié)點(diǎn)的受力性能進(jìn)行計算分析，并對比分析半邊橢圓球單層網(wǎng)殼結(jié)構(gòu)與完整橢圓球單層網(wǎng)殼結(jié)構(gòu)的受力性能差異，另外介紹了該項目風(fēng)洞試驗、風(fēng)荷載取值方法。分析結(jié)果表明，帶高差兩個半邊橢圓球屋蓋結(jié)構(gòu)布置合理，其受力特性與完整圓的網(wǎng)殼結(jié)構(gòu)受力性能存在較大差異。

Abstract: The roof of rock climbing gym in Sub-Plateau Sports Training Base of Guizhou province is shaped as two ellipsoids with height difference. It is the earliest venue in domestic and foreign stadium constructions that adopted two ellipsoid roofs with height difference. The stadium adopts the combined hybrid structural system of ellipsoidal shape Wittur K6 single-layer reticulated shell structure + three-dimensional arch frame + vertical plane cross truss, and the lower part is a reinforced concrete frame-shear wall structure. The structural system selection and structural layout of steel roof were mainly introduced. Multi-model calculation and analysis methods were used to design and analyze the structure and check the stability of the steel roof, the mechanical performance of complex intersecting joints were calculated and analyzed, and the differences in the mechanical performances of the half-elliptical single-layer reticulated shell structure and the complete elliptical single-layer reticulated shell structure were compared and analyzed. The wind tunnel test and wind load value method of the project were also introduced. The analysis results show that the layout of the two-half elliptical sphere roof structure with height difference is reasonable, and its mechanical properties are quite different from those of a complete round reticulated shell structure.
Keywords:rock climbing gym of Guizhou province； large-span steel roof； single-layer reticulated shell； three-dimensional arch frame； wind tunnel test； stability analysis； joint analysis
