高层框架结构地震反应TMD控制研究
Study on the Earthquake Response of High-rise Frame Structures Using TMD Control
【摘要】 对顶部设有水箱的高层建筑的结构地震响应的减震方法及其可行性进行了探讨.在常规动力分析的基础上,将顶层水箱作为TMD子结构系统,以最大绝对位移及层间位移为主要控制值,研究了改变TMD系统参数对框架系统的地震响应的影响.研究结果表明,合理配置TMD系统对减小结构地震反应是可行的,在土木工程中具有广泛应用前景.
【Abstract】 The water tank installed on the top of high - builings is always adopted in engineering practice. However, on the viewpoint of earthquake resistant design, it is more inadvisable. The feasibility of reducing seismic response method is explored to this structural system. Based on the routine dynamic analysis, taking the water tank on the top floor as a TMD substructure, the absolute maximum displacement resonse and the drift of storey as the main controlling values, the effect of seismic response of frame structure is discussed by changing the TMD parameters. The results of investigation demonstrat that reasonable disposal TMD system to reduce the earthquake response of frame structure is feasible, effective and economical, and will be widely used in civil engineering in future.
