Experimental Investigation on the Residual Shear Behavior of 28-Year-Old Decommissioned Prestressed Concrete Voided Slab Girders

Abstract

Abstract A prestressed concrete voided slab girder bridge was decommissioned after 28 years in service near Barrhead, Alberta, Canada, due to severe deterioration. Four interior girders with different deterioration levels were selected and cut into 3.8-m ... Practical Applications The findings in this study provide insights and suggestions for bridge inspectors and engineers when managing aging prestressed concrete voided slab girders. Despite the observed severe deterioration and the artificially induced ...
