［摘要］介紹了廣州融創(chuàng)雪世界高區(qū)的荷載條件及特殊的建筑要求，針對其既是高層又是大跨重載結(jié)構(gòu)的特點，結(jié)構(gòu)設(shè)計選用了“四個落地筒+大跨桁架轉(zhuǎn)換平臺+鋼格構(gòu)柱+大跨鋼屋蓋”的結(jié)構(gòu)體系。為解決傾斜滑道推力造成落地筒彎矩巨大這一關(guān)鍵問題，設(shè)計在落地筒頂部設(shè)置了先滑動后簡支支座群，大幅減小了落地筒彎矩，提高了結(jié)構(gòu)安全性；實測的支座滑移量與理論計算值吻合良好，驗證了支座設(shè)計的合理性。分析結(jié)果表明，結(jié)構(gòu)抗震性能良好，主要抗側(cè)力構(gòu)件均可滿足設(shè)定的性能目標，結(jié)構(gòu)設(shè)計是可行且安全的。

Abstract:The load conditions and special building requirements in the high position zone of Guangzhou Sunac Snow Park were introduced. In view of its characteristics of high-rise and large-span and heavy-load structure, the structural system of four corewalls on ground+large-span truss conversion platform+steel lattice column+large-span steel roof was adopted. In order to solve the critical problem that the bending moment of the corewall caused by the thrust of the inclined race slide was huge, a series of bearings that become simply-supported bearings after sliding were designed at the top of two corewalls on ground, which significantly reduced the bending moment of the corewall and improved the safety of the structure. The measured bearing slip was in good agreement with that of the theoretical calculation, which verified the rationality of the bearing design. The analysis results show that the seismic performance of the structure is excellent, and the main antilateral force components can meet the set performance target, and the structural design is feasible and safe.
Keywords:Sunac Snow Park in Guangzhou; large-span and heavy-load structure; bearing that becomes simply-supported bearing after sliding
