［摘要］三亞亞特蘭蒂斯酒店塔樓建筑立面復(fù)雜，塔樓上部為酒店，外框柱柱距為5.3m；底部3層為餐廳、水療等大開間區(qū)域,外框柱柱距為10.6m；在3～4層采用桁架轉(zhuǎn)換上部密柱。通過斜腹桿、上下水平弦桿、邊跨水平構(gòu)件、轉(zhuǎn)換柱的設(shè)計(jì)以及分析節(jié)點(diǎn)內(nèi)力的傳遞、驗(yàn)證轉(zhuǎn)換層的剛度比對(duì)轉(zhuǎn)換桁架進(jìn)行設(shè)計(jì)，保證了各構(gòu)件抗震性能目標(biāo)的實(shí)現(xiàn)。［關(guān)鍵詞］亞特蘭蒂斯酒店; 轉(zhuǎn)換桁架; 斜腹桿; 水平弦桿; 桁架節(jié)點(diǎn)中圖分類號(hào)：TU318 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2015)24-0072-07
Structural design of transfer truss of Sanya Atlantis Hotel towerLu Ling(Arup, Shanghai 200031, China）Abstract: The facade of the Sanya Atlantis Hotel tower is complicated. The upper part of the tower acts as hotel with outer frame column spacing of 5.3m. The bottom 3 layers of the tower acts as a large space region with restaurant and hydrotherapy spa with outer frame column spacing of 10.6m. Transfer trusses are adopted in layers of 3 and 4 with upper close columns. Transfer trusses are designed in following process to ensure the achievements of seismic performance objectives of members, including oblique web member design, upper and lower horizontal chord member design, side span horizontal member design, transfer column design, joint internal force transfer analysis and verification of stiffness ratio for transfer layer.Keywords: Atlantis Hotel; transfer truss; oblique web member; horizontal chord member; truss joint
