单层工业厂房-TMD减震控制系统研究
|
摘要
提出了采用质量调谐减震控制技术对厂房结构进行减震控制的方法。利用屋盖系统作为附加质量,屋盖支座采用夹层橡胶隔震垫,建立了厂房-TMD系统模型,并用非线性时程分析法对其进行了多种地震动激励下的计算分析,探讨了厂房-TMD减震体系减震效果的参数影响及减震机理。结果表明,采用质量调谐减震技术对单层工业厂房进行减震是一种有效的方法。
The TMD control technique is used in seismic energy releasing of the single-storey industrial building with roof system as mass and rubber isolation bearing as supporting. The earthquake responses of the TMD system excited by ground motions were investigated with non-linear time history analysis procedure . The parameter influences on decreasing amplitude and seismic energy releasing mechanism were also discussed. The results show that TMD control technique is an efficient method for earthquake resistance of the industrial building. The average response ratio of the controlled structure to that of not controlled structure is between 0.41 and 0.88.It also shows that frequency spectrum and intensity of ground motion have effect on the control effectiveness of the system. And control effectiveness is relative to the ratio of characteristic frequency of input ground motion to the fundamental frequency of industrial building and amplitude of input ground motion. So different strategies should be adopted in terms of the control target for practical industrial building.
