摘要
利用喜来登环球旅馆于1994年北岭地震中获得的强地震反应观测记录,运用卡尔曼滤波识别了该旅馆结构刚度在地震过程中的时变规律,并对该结构的表现做出初步解释。本文工作可作为进一步研究喜来登旅馆这类建筑结构实际抗震性能的基础。
The time-variant properties of the restoring forces of Sheraton-Universal Hotel are identified using the 1994 Northridge earthquake records that have been got in it.Furthermore the time-variant regulations of the structural stiffiness could be obtained through using kalman filter.Then the reasons for the behavior of the structure are presented.The results in the paper could provide the basis for the further research on seismic properties of the similar structure of the Sheraton-Universal Hotel
