建筑物模态参数时变特性基于强震记录的识别

IDENTIFICATION OF TIME-VARIANT MODAL PARAMETERS OF BUILDING FROM STRONG EARTHQUAKE RECORDS

本文提出一种封闭循环滤波方法,根据等效线性化原理,利用新北京饭店在唐山地震中的强震观测记录,识别建筑物模态参数的时变特性。

In this paper an equivalent linearization and a closed-loop filter method are provided to identify time-variant modal parameters of the new Beijing Hotel Building using strong earthquake records obtained from Tangshan Earthquake.
