［摘要］針對重慶來福士廣場南塔不對稱的外框柱立面造型進行了P-Δ影響分析、穩(wěn)定性屈曲驗算以復(fù)核結(jié)構(gòu)穩(wěn)定性及安全性，對曲線引起的水平變形進行了復(fù)核。針對結(jié)構(gòu)平面及立面開洞，通過結(jié)構(gòu)振型對比判斷外框梁、連梁、避難層墻體等連系構(gòu)件的重要程度及敏感性，對其在左右半塔不同水平力工況下進行了承載力驗算，并在核心筒不對齊開洞兩側(cè)采用增設(shè)扶壁柱及局部樓板加厚等構(gòu)造措施。針對4座塔樓屋頂與空中連橋相連，進行了單塔及多塔模型對比分析，塔樓按包絡(luò)工況進行設(shè)計，分析結(jié)果也給空中連橋的基礎(chǔ)支座設(shè)計與塔樓之間的相互作用分析提供參考。［關(guān)鍵詞］重慶來福士廣場; 不對稱曲線立面; 多塔; 核心筒曲線開洞; 超高層建筑; 抗震設(shè)計中圖分類號：TU375.4 文獻標(biāo)識碼：A 文章編號：1002-848X(2015)24-0001-08
Structural design for south towers of Raffles City in ChongqingHan Xiaojuan1, Zhu Ligang1, Tu Wanglong1, Luong Andrew1, Wang Aaron2（1 Arup, Shanghai 200031, China; 2 Capitaland China Investment Co., Ltd., Shanghai 200001, China）Abstract: Due to asymmetric outer frame column faade of south towers in Chongqing Raffles City, P-Δ analysis and stability buckling calculation were carried out to confirm structural stability and safety. Horizontal displacement due to curves was also checked. For cases of structural plane openings and faade openings, importance degree and sensitivity of key linked members were determined according to structural dynamic mode shape comparisons, such as perimeter frame beams, coupling beams and shear walls in refugee floor. And bearing capacity checking was carried out in the left and right half towers under different horizontal force working conditions. Construction measures were taken to corewall unaligned openings including set of counterforted columns at two ends of corewall unaligned openings and local floor thickening. Considering that four tower roofs were connected with a sky bridge, the single tower model and multi-tower model were compared and analyzed, and the tower was designed according to envelope working conditions. The analysis results also provided reference for foundation base design of the sky bridge and the interaction analysis of the sky bridge and the towers.Keywords: Raffles City in Chongqing; asymmetric curved faade; multi-tower; corewall with curved opening; super-tall building; seismic design
