| 摘 要： | 本文在运用复模态法求得多自由度带TMD结构随机地震响应解析解的基础上．采用基于动力可靠性约束的优化设计方法对TMD装置参数的优化取值进行了系统研究，以结构最大位移响应的期望值为目标函数，以TMD装置响应的动力可靠性为约束条件，运用罚函数法获得到TMD装置的优化设计参数．并给出了算例，从而建立了带TMD结构基于动力可靠性约束的抗震优化设计的一整套方法，本文方法也可用于基础隔震结构、带TLD减震结构以及带TMD和TLD抗风结构的优化设计。

| Abstract: | In this paper,on the basis of the exact solutions of random earthquake response of the multistory structure with TMD got by using complex mode method, the optimal parameters of TMD equipment are studied systematically by using the dynamic reliability-based optimum design. Under the dynamic reliability constraint of the response of the TMD equipment, the mean largest displacement of the main structure is taken as the objective function. The optimal design parameters of TMD equipment are got by the penalty function method and an example is given. Therefore, a series of methods of dynamic reliability-based seismic optimal design for the structure with TMD are established. The method of this paper can be used to the optimal design of base-isolation structures and structure with TLD and the wind-resistant optimal design of structure with TMD and TLD. |
