摘要
针对一非对称阻尼耗能双塔连体结构,建立了对应的动力分析模型和振动方程,推导出该结构体系的传递函数矩阵,并对所获得的传递函数进行基于动力特性相同原则的等效降阶处理,得到该结构体系在‘THBCC-1型信号与自动控制试验台’上进行试验分析的等效电路图。分别采用试验电路模拟和数值仿真两种方法对该连体结构进行天然地震荷载EL-Centro1940波作用下的地震响应研究,研究结果表明:等效模拟试验电路模型和原系统具有较好的相似性,两种分析方法所获得地震响应的结果非常的接近,说明了本文所提方法分析连体结构地震响应的有效性。
Aimed to an unsymmetrical damping energy double-tower connected structure,a corresponding model of dynamic analysis and vibration equation were established,the transfer function matrix of the structure system was deduced from the state space expression.The obtained transfer functions were simplified by means of equivalent reduced order based on the same principles of dynamic characteristics,and the equivalent circuit diagram of ‘THBCC-1 Signal and Automatic Control Experimentation Table′ can also be obtained.Experimentation circuit simulation and numerical simulation were used to discuss the seismic response of the connected structure under the EL-Centro1940 wave along the connection direction.Studing results show that:the equivalent circuit model and the original system has better similarity,the seismic response results is very closed while the two analytical methods were used,the analytical method that mentioned in this article is available to analysis the seismic response of the unsymmetrical connected double-tower structure.
