【摘要】 对于带TMD控制装置的高层结构风振响应问题,由于风荷载和结构响应具有随机性,运用基于动力可靠性约束的优化方法对TMD装置的系统参数进行优化设计是十分必要的和合理的。在运用复模态法和扩阶法得到结构和控制装置随机风振响应的基础上,以TMD装置响应的动力可靠性作为约束条件,以主体结构广义位移的最大响应均值最小为目标函数,运用罚函数法对TMD装置的系统参数进行优化取值,建立了带TMD高层结构基于动力可靠性约束的抗风优化设计的方法。更多还原

【Abstract】 The optimum design method based on dynamic reliability constraint is necessary and reasonable for the optimal parameters of TMD equipment because of the randomness to wind and responses of the structures with TMD.Under the constraint of dynamic reliability of the response of the TMD equipment,and taking the max mean response of broad sense displacement of the main structure as the objective function,the optimal design parameters of TMD equipment are obtained by the penalty function method in the basis of that the exact solutions of random wind-induced response of the structure with TMD are obtained by using complex mode method and expanding rank method.Therefore,the optimal design method for the random wind-induced response of high-rise structure with TMD based on the constraint of dynamic reliability is established.The method proposed in the paper can be used in the optimization design of base-isolation structure,shock absorption structure with TMD and random wind-induced response and random earthquake response of structure with TLD.更多还原
