某带钢-混凝土组合桁架转换超限高层结构设计

Structure Design of a High-rise Building beyond the Code with Steel-Concrete Composite Transfer Truss

介绍了某带钢-混凝土组合桁架高位转换超限高层结构的抗震概念设计、抗震计算分析、主要抗震措施以及节点构造设计。分析表明转换桁架下弦、腹杆采用钢结构、上弦结合楼板采用钢骨混凝土结构这一能充分发挥材料各自长处的新型组合转换结构性能优良,具有十分广阔的应用前景。

The paper introduces the aseismic concept design, seismic analysis, aseismic measure and detail design of a high - rise building with steel - concrete composite transfer truss which is out of the current code. The analysis reveals that the composite truss, which is made of steel bottom chords, steel web members and SRC top chords with concrete floor, could exert merit of each material. This type of structure has large practical foreground.
