【摘要】 为获得带TMD的建筑结构在随机风荷载作用下基于舒适度约束下的TMD装置的最优参数.首先获得了与舒适度相关的结构一阶模态加速度风振响应的解析解;然后定义结构在设置TMD和不设置TMD的风振加速度之比作为减振效果指标,并以之为优化目标;最后运用复形法得到TMD装置的优化设计参数.研究表明,该方法能有效获得TMD装置的最优参数.更多还原

【Abstract】 Optimal parameters of TMD devices are to be obtained which are equipped on the building structure under random wind loads based on comfort constrained.Firstly,the analytical solution for the acceleration of wind-induced response associated with the comfort of the structure of the first-order mode is got.Secondly,the ratio of the standard deviation of the first-order modal acceleration of the structure with TMD dampers to that without TMD dampers is defined as the index of damping effect and it is used as the optimal objective.Finally,the optimal parameters of TMD dampers are got by Complex Method.Studies have shown that the method can effectively obtain the optimum parameters of TMD devices.更多还原
