Concrete cracking in new bridge decks and overlays
(Wisconsin Highway Research Program, 2010-02)
There appears to be a trend for new bridge decks in the state of Wisconsin to develop early-age transverse cracks and map cracks on concrete overlays. A comprehensive literature review of the potential causes of concrete ...
Fatigue risks in the connections of sign support structures: phase I
(Wisconsin Highway Research Program, 2008-12)
Wisconsin sought to assess the risk of fatigue-induced fracture in its existing sign support structures designed before the latest AASHTO specifications that included fatigue design. A framework for assessing fatigue-induced ...
In-situ monitoring and testing of IBRC bridges in Wisconsin
(Wisconsin Highway Research Program, 2010-06)
This study examines two highway bridges constructed using novel fiber-reinforced polymer (FRP) composite stay-in-place formwork and an FRP grillage reinforcement system. Both bridge superstructures rely on the FRP components ...
Structural analysis of sign bridge structures and luminaire supports
(Wisconsin Highway Research Program, 2004-03)
The Wisconsin Department of Transportation has experienced failures of a high-mast luminaire (HML) support structure and a full-span overhead sign support structure. Furthermore, cracking has been found in many sign support ...
