Behavior of a 3-Span Continuous Bridge Before and After Continuity Joint Replacement Using Ultra-High-Performance Concrete
Publisher: ASCE
Abstract: One method of bridge construction consists of simply supported precast, prestressed concrete girders made continuous for live load through individual continuity joints connecting the two girder ends from adjacent spans. ...
Concrete Bond and Behavior of Nonproprietary Ultrahigh-Performance Concrete Bridge Slab Joints
Publisher: ASCE
Abstract: The purpose of this study was to evaluate a nonproprietary ultrahigh-performance concrete (UHPC) mix design in terms of bond strength and behavior as a slab joint material. Composite modulus of rupture and direct pull-off ...
Testing and Evaluation of Polyurethane-Based GFRP Sandwich Bridge Deck Panels with Polyurethane Foam Core
Publisher: American Society of Civil Engineers
Abstract: This paper presents the evaluation of an innovative low-cost small-scale prototype deck panel under monotonic and fatigue bending. This new system introduces a trapezoidal-shaped polyurethane foam core with a thermoset ...
Modeling and Analysis of GFRP Bridge Deck Panels Filled with Polyurethane Foam
Publisher: American Society of Civil Engineers
Abstract: This paper presents finite-element analyses and analytical models of innovative, small-scale, prototype deck panels examined under monotonic bending. The deck panels consisted of two glass fiber–reinforced polymer (GFRP) ...
Excessive Approach Pavement Pressure against Conventional Bridges
Publisher: ASCE
Abstract: Thermally induced stresses can build up in rigid pavements without pressure relief joints. The pressure created becomes a problem for adjacent structures such as bridges. The pressure can cause the pavement to push on the ...
