摘要:
介绍了广西地区某四边形塔架在台风“威马逊”作用下的破坏模式，并采用SAP2000软件对在台风中破坏的塔架进行
了有限元分析．分析结果表明：当风速达到35 m/s时，该塔架就会因主杆失稳而倒塌，失稳杆件的位置与实际的破坏位置吻
合；同时，45°方向的风向对此类结构的影响比90°方向的风向更为不利．为给今后的重建工程提供一定依据，还对该类结构
在40 m/s和50 m/s的大风条件下进行了初步设计和经济性分析．
Abstract:
The failure phenomena of a quadrilateral shape steel tower under the typhoon "Ramasun" in Guangxi area is described,
and these failure steel towers during the typhoon period are analyzed by finite element analysis with SAP2000 software. The result
shows that the tower structure is failed by the chord member buckling when the wind speed is up to 35 m/s, and the location of the
buckling is consistent with the actual. In addition, for such structures, the 45° direction wind is more detrimental than 90° direction
wind. Finally, in order to provide a basis for future reconstruction project, this paper also completes the preliminary design of such
structure in 40 m/s and 50 m/s high wind conditions, and its economy is discussed.
