基于双塔连体结构柔性连接体系的3自由度(3-DOF)力学模型,利用虚拟激励法分析了连接构件的频率比、阻尼比和质量比等参数对该复杂结构体系地震反应的影响。根据不同的控制目标,得到了对称双塔连体结构柔性连接体系支座优化设计参数变化规律和连接参数的优化组合用以指导此类结构的减震初步设计。最后以某实际工程为算例进行数值分析,验证了优化理论的正确性。

Based on the Siamese Twin Towers Structural Flexibility to connect the system 3 degrees of freedom(3-DOF) mechanical model,using pseudo-excitation method to connect components analysis of the frequency ratio,damping ratio and mass ratio and other parameters of the seismic response of complex structural systems impact.Depending on the different control objectives,the supports optimal design parameters of variation and connections and the optimized combination of parameters of Siamese twin symmetric structure flexible connection system have been obtained to guide the preliminary design of such structural damping.At last,for the example of a practical engineering,the numerical analysis is performed to verify the correctness of the optimization theory.
