［摘要］青岛科技馆主楼为现浇混凝土框架-剪力墙结构，框架体系包含混凝土框架和钢混凝土组合结构框架。为实现建筑效果，在结构的南北立面各抽掉3根框架柱，形成跨度为59m钢结构转换桁架。针对此种情况，采用YJK和MIDAS/Gen软件进行了对比分析，通过静力弹塑性分析找出结构薄弱部位，并采取相应的加强措施。

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
