Flexural anchorage performance and strengthening on negative moment regions using near-surface mounted retrofitting in reinforced concrete bridge girders

Creator:

Barker, Laura

Abstract:

Large numbers of reinforced concrete deck girder (RCDG) bridges were built during the highway infrastructure boom of the 1950's. The advent of standardized deformed steel reinforcing bars during this time allowed for straight bar terminations in flexural tension regions. Designers of the time terminated reinforcing bars where they were no...

Application of Titanium Alloy Bars for Strengthening Reinforced Concrete Bridge Girders in Flexure

Creator:

Vavra, Eric

Abstract:

Structurally efficient and cost-effective solutions are needed to extend the service-life of deficient and aging highway infrastructure around the world. One critical need is to increase the flexural strength of older reinforced concrete (RC) structures to carry heavier and more frequent loads. Titanium alloy bars (TiAB) offer a new opportunity...

Masters Thesis
Design and fatigue behavior of near-surface mounted CFRP bars for shear strengthening of RC bridge girders

Creator:

Johnson, Brandon Ang

Abstract:

Carbon fiber reinforced polymer (CFRP) materials are emerging as an effective means of strengthening and rehabilitating bridges. Near surface mounting (NSM) is a newer technique for application of CFRP for retrofitting of bridge members that provides advantages over conventional strengthening techniques. The technique is still new and uncertainties remain regarding...
