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。
China Women and Children Museum, a total of six southern, north with four mezzanines a total of 10 layers, the highest elevation of 38.7m. The use of reinforced concrete frame structure, curved surface construction using welded H-beam, a plane, vertical irregular multiple high-rise steel-concrete composite structure. The seismic calculation is carried out by using SATWE and ETABS programs. The seismic performance of the steel frame involved in the calculation of the lateral resistance force is compared. The response of the steel frame and the concrete connection point under the action of multiple seismic waves is analyzed with different damping ratios. The results show that: 1) For the complex high-rise steel-concrete composite structures, it is necessary to establish the overall analysis model including all the steel members and concrete structures; 2) For the convenience of structural reinforcement, the concrete structure model is used for calculation and proper correction It is also feasible to strengthen the measures. 3) The connection of steel and concrete is the key to the design of anti-seismic overrun. It is suggested to consider the anti-seismic performance of medium-elastic earthquake.
