［摘要］中国妇女儿童博物馆南部共6层，北部含4个夹层共10层，建筑最高点标高38.7m。采用钢筋混凝土框架结构，曲面建筑造型采用焊接H型钢，属于平面、竖向多项不规则的复杂高层钢-混凝土组合结构。采用SATWE，ETABS程序进行抗震计算分析，比较了钢架参与抗侧力计算与否结构的抗震性能，采用不同阻尼比重点分析了钢架和混凝土连接点在多个地震波作用下的反应。结果表明：1)对于复杂高层钢-混凝土组合结构，建立包括全部钢构件、混凝土结构的整体分析模型是必要的；2)为方便结构配筋，采用混凝土结构模型进行计算并作适当的修正和加强措施也是可行的；3)钢、混凝土连接节点是抗震超限设计的关键，建议按中震弹性的抗震性能指标考虑。

Abstract:Women and Children Museum of China is the steel and concrete mixed structure  with 6 stories and the north of the building are 10 stories including 4 inter layers, which has incredible curved surface achieved by steel flange beam. SATWE and ETABS softwares are used in the structure earthquake analysis. Two analysis models those are concrete one and mixed structure one are respectively calculated and the earthquake resistance capabilities of the building are also compared in two states. The different damping ratio is an another important parameter in analysis, the results of steel and concrete node force are listed in different damping ratio. The conclusions show that： (1) For the complicated tall mixed structure, the essential work is to build an accurate modeling in design procedure；(2) The concrete modeling is feasible in analysis considering some seismic parameter adjusting and the fortification measure is adopted； (3) The key point of seismic fortification is the steel-concrete joints calculation when out of code, and this kind of jonts can be designed in comformity with the middling elastic seismic fortification.
Keywords:steel-concrete hybrid tall building; modeling; damping ratio; seismic calculation; seismic fortification measures
