摘要
华敏帝豪大厦塔楼结构方案在综合考虑结构抗震性能、建筑功能及经济性后,外围框架柱和转换斜撑采用矩形钢管混凝土构件。介绍了矩形钢管混凝土结构的计算、构造和节点,着重阐述了钢管混凝土斜撑转换构件的设计和构造,并用有限元程序ANSYS对重要节点进行分析。工程实践表明,矩形钢管混凝土结构承载力高、抗震性能好,可显著减小柱断面,与钢框架梁连接方便。最后介绍了矩形钢管混凝土施工中的重要问题。
Considering the seismic performance,architectural requirements and cost saving,concrete-filled rectangular steel tube members are adopted as frame columns and inclined column transfer structures in Huamin Imperial Tower.The analysis and connections of concrete-filled rectangular steel tube members were introduced.The design and joints of inclined column transfer structures with the member of concrete-filled rectangular steel tube were expounded.The analysis using the finite element analysis program ANSYS was carried out for the important joint.The engineering practice shows that the using of concrete-filled rectangular steel tube members reduces the size of the columns,and it is a convenient way to connect steel beams and columns.At last,the important problems in the construction of concrete-filled rectangular steel tube were introduced.
