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 ...
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 ...
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 ...
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 ...
