Performance evaluation of hinges in cantilever steel truss bridges by temperature induced strain

Abstract

In this study, short-term monitoring using more than a hundred sensors was carried out for an existing long-span bridge, which has been administrated by a local government, with the aim of evaluating its present performance toward planning future maintenance strategy. The bridge studied is a cantilever (Gerber) steel through truss bridges that was completed and opened to the traffic in 1937. Consequently, the performance of Gerber hinges were evaluated, then information for prior repair was obtained.
