大连维多利亚广场A塔楼外框采用矩形钢管混凝土柱。介绍了矩形钢管混凝土柱的设计分析方法及节点构造等内容;重点探讨了矩形钢管混凝土柱在地下室部分的设计与构造以及伸臂桁架等关键节点的传力构造,并采用有限元软件对关键节点进行分析;最后阐述了矩形钢管混凝土的施工及检测方法。通过理论分析及工程实践,证明矩形钢管混凝土柱承载力高、抗震性能优越、施工方便,在超高层结构中具有一定的优势。
A tower in Dalian Victoria Square frame rectangular steel tube concrete column. This paper introduces the design and analysis methods of rectangular CFST columns and the structure of nodes. The design and construction of rectangular CFST columns in the basement and the transmission structures of the key nodes such as boom trusses are discussed emphatically. The finite element software Finally, the construction and testing methods of rectangular CFST are described. Through theoretical analysis and engineering practice, it is proved that rectangular CFST columns have high bearing capacity, superior seismic performance, convenient construction and superiority in super high-rise structures.
