［摘要］青島科技館主樓為現(xiàn)澆混凝土框架-剪力墻結(jié)構(gòu)，框架體系包含混凝土框架和鋼混凝土組合結(jié)構(gòu)框架。為實(shí)現(xiàn)建筑效果，在結(jié)構(gòu)的南北立面各抽掉3根框架柱，形成跨度為59m鋼結(jié)構(gòu)轉(zhuǎn)換桁架。針對此種情況，采用YJK和MIDAS/Gen軟件進(jìn)行了對比分析，通過靜力彈塑性分析找出結(jié)構(gòu)薄弱部位，并采取相應(yīng)的加強(qiáng)措施。

Abstract:The main building of Qingdao Science and Technology Museum is the cast-in-situ concrete frame-shear wall structure, and the frame system includes concrete frame and steel-concrete composite structure frame. In order to achieve the architectural effect, three frame columns are removed respectively in the north and south facades of the structure, forming a 59m-span steel structure transfer truss. In view of this situation, the comparative analysis was carried out by YJK and MIDAS/Gen programs. Push-over analysis was conducted to find the weak parts of the structure, and the corresponding strengthening measures were taken.
Keywords: Qingdao Science and Technology Museum； large-span transfer truss； steel reinforced concrete composite structure
