摘　　要：为了探究钢混组合式塔架结构(混塔)在风载荷和地震波联合作用下的结构响应,建立了钢混组合式塔架的有限元模型,采用Davenport脉动风速谱,基于AR线性滤波法对脉动风速进行时程模拟;并基于结构所处的场地条件,对混塔进行相应的地震波时程分析。在此基础上,采用基础隔震结构、单个调谐质量阻尼器(single tuned mass damper, STMD)和分布式多重调谐质量阻尼器(distributed multiple tuned mass damper, D-MTMDs)结构、以及隔震结构和D-MTMDs结构组合而成的混合控制结构等一系列控制方法对混塔的响应进行了控制,并采用了七种评价指标对各控制方法的优劣进行了相应的评估。计算结果表明,混合控制结构可以结合隔震结构和D-MTMDs结构的控制优点,不仅展现对风载响应的良好控制,也显示出对风载和地震波联合载荷响应优异的控制效果。Here, to explore structural response of steel-concrete composite tower structure(hybrid tower) under the combined action of wind load and seismic wave, the finite element model of hybrid tower was established. Davenport fluctuating wind speed spectrum was adopted, and the time history simulation of fluctuating wind speed was performed based on AR linear filtering method. Based on site conditions of hybrid tower structure, the corresponding seismic wave time history analysis of hybrid tower was done. Then, a series of control methods, such as, base isolation structure, single tuned mass damper(STMD) and distributed multi-tuned mass dampers(D-MTMDs) structure as well as hybrid control structure composed of isolation structure and D-MTMDs structure were adopted to control hybrid tower response, and 7 evaluation indexes were adopted to evaluate advantages and disadvantages of various control methods. The calculation results showed that hybrid control structure can combine control advantages of isolation structure and D-MTMDs structure;hybrid control structure can not only reveal good control over hybrid tower response to wind load, but also exhibit excellent control effect on its response to combined load of wind load and seismic wave.
