摘要: 中海成都天府新區(qū)超高層項目采用 8 根巨柱的巨型框架-核心筒-伸臂桁架結(jié)構(gòu)體系,建筑外立面沿高度錐形收進(jìn)。 巨柱雙向內(nèi)傾,角部兩巨柱最小距離控制不小于 9. 4m,相對應(yīng)角部結(jié)構(gòu)最大凈懸挑 12. 45m。 為保證樓面結(jié)構(gòu)具有足夠的冗余度,采用兩階段方法進(jìn)行設(shè)計。 建筑角部與懸挑部位舒適度控制尤為重要,結(jié)合幕墻龍骨位置,創(chuàng)新性地采用振動桿技術(shù),通過串連避難層之間 8 層樓面的方式大幅改善樓蓋舒適度,在實現(xiàn)超長結(jié)構(gòu)懸挑、營造角部無柱空間、保證絕佳視覺體驗的同時也確保了結(jié)構(gòu)的安全性與經(jīng)濟(jì)性。

Abstract: China Overseas Property Chengdu Tianfu New District super high-rise project adopts a mega frame-corewalloutrigger structural system with 8 giant columns. The building facade is taperly set back along the height. The giantcolumns are inclined inward in two directions, and the minimum distance between the two giant columns at the corner iscontrolled to be no less than 9. 4m, and the maximum net cantilever of the corresponding corner structure is 12. 45m. Inorder to ensure that the floor structure has sufficient safety redundancy, the two-stage design method was adopted. Thecomfort control of the cantilevered part of the corner of the building was particularly important. The vibrating rod technologywas innovatively adopted combined with the position of the curtain wall keels to greatly improve the floor comfort byconnecting 8 office floors between the refuge floors in series. This realized the super-long floor cantilever, created columnfree corners, created an excellent visual experience and realized the safety and economy of the structure.
Keywords:mega structure; corner super-long cantilever; two-stage design method; vibrating rod; floor comfort
