RISPrediction of Moment–Curvature Response and Maximum Bending Resistance for Hybrid NSC-UHPC Elements
Publisher: ASCE
Abstract: Exceptional mechanical properties of ultra-high performance concretes (UHPC) offer strong strengthening capacities in bending and shear when used as overlay on normal strength concrete (NSC) structures. Nonetheless, lack ...
Experimental Investigation of the Shear Resistance Mechanism on Hybrid NSC-UHPC Predamaged and Undamaged Unidirectional Bridge Slabs
Publisher: ASCE
Abstract: This paper investigates the shear behavior of unidirectional hybrid slabs made of a normal-strength concrete (NSC) substrate and an ultrahigh-performance concrete (UHPC) overlay on the tensile side. The impacts of two ...
Static and Dynamic Behavior of High- and Ultrahigh-Performance Fiber-Reinforced Concrete Precast Bridge Parapets
Publisher: American Society of Civil Engineers
Abstract: New designs of precast bridge parapets made with fiber-reinforced concrete (FRC) were developed using nonlinear finite-element calculations. Specific properties of high- and ultrahigh-performance FRC were exploited in these ...
