摘要
在汶川渔子溪村灾后重建工程中,采用了方钢管混凝土组合异形柱结构体系。利用MIDAS/Gen软件对其进行建模分析,分析了结构在各种工况下的静力特性,从结构的自振周期、异形柱连接板应力、柱底反力、外肋环板节点承载力等方面初步验证了设计的合理性。对结构的建造方法进行了简单介绍,说明异形柱和外肋环板节点施工快捷方便。
Special-shaped concrete-filled square steel tubes( SCFST) structure was adopted in Wenchuan reconstruction project. The static characteristics of the SCFST structure was studied based on the MIDAS software. The natural vibration period,the stress of special-shaped column batten plate and the reaction force at the column base were analyzed which could verify the rationality of the design. The construction method of structure was introduced briefly which could show the easy construction of SCFST and the vertical stiffener joint.
