［摘要］為舉辦特定重要國際會議，青島國際會議中心為在已有建筑上的改造加建項(xiàng)目。設(shè)計(jì)時保留原有地下室結(jié)構(gòu)，采用加大截面法對部分地下室柱進(jìn)行加固，采用在原筏板基礎(chǔ)上增設(shè)獨(dú)立基礎(chǔ)方法對部分筏板基礎(chǔ)進(jìn)行加固。新建上部結(jié)構(gòu)采用鋼框架，并充分利用原柱網(wǎng)系統(tǒng)，通過局部抽柱形成大跨度空間。本項(xiàng)目多功能廳32m大跨度采用開孔變截面鋼梁；主入口雨棚懸挑跨度達(dá)29m，采用開孔變截面鋼梁；沿建筑周邊的穿層柱列最大高度為24-0m，長細(xì)比大，采用方鋼管混凝土柱解決其穩(wěn)定問題。通過采用合理的結(jié)構(gòu)方案，以及與建筑專業(yè)的密切配合，可很好地實(shí)現(xiàn)建筑功能及建筑造型要求，以及項(xiàng)目快速建造的要求。

Abstract:To organize specific major international conference, Qingdao International Convention Centre is reconstructed on an existing building. The underground structure was retained, part of original columns was enlarged and strengthened, and part of original raft foundations was strengthened by adding independent foundations. Steel framed system was adopted for the new structure above the ground. The new construction utilized original column grid system and increased length of spans by removing part of columns. Variable-section opening steel beams that span 32 meters were adopted for multi-function room. The span of cantilevered canopy on main entrance is 29 meters, which variable-section opening steel beams are used for the structure of the canopy. The piercing columns around the building are 24 meters height, and because of the large slenderness ratio, square concrete-filled steel tubular columns were used to solve the problem of stability. Choosing reasonable structure plans and collaborating closely with architectural department help achieving not only the needs of architectural function but also the requirement of architectural image, and the requirement of rapid construction.
Keywords:Qingdao International Convention Centre; steel framed system; variable-section opening steel beams; cantilever canopy with large span; piercing column; stability analysis
