在公路橋梁養護中，超載破壞是很重要的一個課題，特別是在交通樞紐亦或是貨運量大的重要路徑，其破壞程度尤其嚴重，因此建立出橋梁荷載譜是橋梁永續經營必要課題，可用來檢視橋梁受到重車不斷的循環加載行為時，是如何影響橋梁壽命及使用年限，作為評估強度和進行補強的依據。建立橋梁荷載譜的第一步就是要能算出車輛之軸重和總重。本研究之目的就是發展移動車輛載重識別(Weigh-In-Motion)的方法，透過對車輛與橋梁結構之互制行為之監測數據，進行車輛載重的反算。 ;The overloading failure is a very important issue for the maintenance of highway bridges, especially for the bridges on the path of heavy trucks. Therefore, it is necessary to know the loading spectrum of the bridges undergoes for their sustainability management. This can be used to conduct the fatigue life analysis, degradation evaluation and retrofit works of bridge structures. The goal of this research project is to develop techniques for the identification of moving vehicle loads on bridge through monitored strain and deflection data.
