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...

Moment Regions Using Near-Surface Mounted Retrofitting in Reinforced Concrete Bridge Girders
Methods for strengthening flexural steel details in reinforced concrete bridge girders using a near-surface mounted retrofitting technique

Creator:

Amneus, Deanna

Abstract:

Many older reinforced concrete deck girder (RCDG) bridges contain straight bar terminations of flexural reinforcement. Common bridge design practice of the 1950s did not consider the additional demands on the terminated bars from shear and flexure. Moreover, more stringent code specifications and heavier permit trucks contribute to the insufficient ratings...
