Experimental Analysis on Strengthening Materials of Orthotropic Steel Bridge Decks

Abstract:

Application of orthotropic steel bridge decks has become increasingly widespread, but with the growing traffic, the bridge decks frequently get fatigue damage, even forming cracks. This paper makes an overall analysis on the orthotropic steel bridge decks cracks of a certain bridge in Southern China, and experimentally studies on both in-situ and new strengthening materials, including low temperature impact toughness, conventional mechanical properties and fatigue performance. Test conclusions indicate that the two materials have good performance, which means the cracks have no business of in-situ materials, and the strengthening materials can be put into use.
