交通部氣象局強震網計畫，已於重陽橋等十三座橋梁安裝強震儀及集錄系統，收集多量地震及橋梁結構反應資料，其中已有數座橋梁及收集資料經詳細分析，成果可供工程應用之參考。本計畫擬利用台北市東西向快速道路橋梁安裝強震儀段收集之資料，檢討橋梁耐震設計規範中相關問題，同時進行橋梁之耐震能力分析，供檢討修訂橋梁耐震設計規範之參考與Haz-Taiwan計畫之應用。 The Taipei East-West Express Highway Bridge is one of special type steel bridge in Taiwan area. In order to understanding the structural characteristics and earthquake responses of the bridge, strong motion accelerometers have been installed on the bridge as well as on free fields by National Central Bureau of Weather. The objective of the present study is to analyze the seismic data by using techniques of system identification. The parameters estimated by system identification can be used to understand the dynamic characteristics of the bridge. In additional, a finite element model has been set up to evaluate the seismic capacity of the bridge by using push over test. The results obtained can provide some suggestions for earthquake resistant design of this type and information for Haz-Taiwan Program. 研究領域：8808 ~ 8912
