Title Alternatives to Steel Grid Decks - Phase II, Summary Report.
Publication Date Sep 2012
Media Count 1p
Personal Author A. Mirmiran
Abstract Researchers first investigated the long-term performance of the UHPC bridge deck system. They conducted a series of tests, including shear and uplift testing of deck-to-girder connections, deck-to-deck connection tests, lateral distribution of live loads, and fatigue and residual strength tests. This work revealed that due to the unique properties of UHPC, both mechanical properties and failure modes including ductile shear and bond failure of reinforced members of UHPC differed from normal strength concrete. Further study of UHPC failure modes included dowel action shear tests and uniaxial fatigue tests. The researchers noted the significant contribution of dowel force.
