Cable Force Analysis of Gi-Lu Cable-Stayed Bridge after Gi-Gi Earthquake
作者 李政寬張國鎮羅俊雄陳建州周智傑黃新愷
英文摘要
Located at central Taiwan, Gi-Lu Bridge is a modern designed pre-stressed concrete cable-stayed bridge, which crosses the longest river(Juosheui River) in Taiwan. With two 120-meter spans and harped sixty-eight cables, the bridge is supported by a single pylon and two bents at the ends of the spans. On September 21, 1999, near upon the constructional completion of Gi-Lu Bridge, a significant earthquake(Gi-Gi Earthquake) with 7.3 ML magnitude seriously struck the central Taiwan. For only three kilometers away from the epicenter, the bridge underwent very strong ground shaking and its several structure members broke. From the view point of structure engineering, Gi-Gi Earthquake had serious damaged the bridge and the cable forces had redistributed. Therefore, the primary research objective of this project is to identify the present cable forces and build some charts to monitor the future cable system under repair work.
