提出了一种针对安装了摩擦阻尼器的高耸塔架结构的双模型动力分析方法。为满足摩擦阻尼器对高耸塔架结构振动控制的特殊需要 ,建立了高耸塔架结构的三维空间有限元静力模型和二维串联多自由度动力模型 ,并在形成控制力变换矩阵和计算摩擦阻尼器两端的相对位移的过程中综合地运用了这两种力学模型。还以国内拟建的第一高钢结构电视塔——合肥电视塔作为算例进行了摩擦阻尼器风振控制的分析研究
A dual-model dynamic analysis method for high tower structure with friction damper is proposed. In order to meet the special needs of friction dampers for vibration control of towering tower structures, a three-dimensional finite element model and a two-dimensional tandem multi-degree-of-freedom dynamic model for towering tower structures are established. After forming control force transformation matrix and calculating friction The two mechanics models are used together in the relative displacement of the damper at both ends. An analysis of the wind-induced vibration control of the friction damper is also carried out by using the Hefei TV Tower, the first proposed high-tech steel television tower in the country.
