Seismic Performance of Square Reinforced Concrete Columns Retrofitted with Titanium Alloy Bars

Creator:

Lostra, Mackenzie M. W.

Abstract:

Large numbers of reinforced concrete (RC) bridges were built in the past that are now considered seismically deficient. The structural members most likely to be considered deficient are the supporting columns. Typical deficient columns contain inadequate transverse reinforcement and poorly detailed lap splice lengths above the foundation. Insufficient lap splice...

Seismic performance of reinforced concrete bridge columns constructed with grade 80 reinforcement

Creator:

Link, Tim B.

Abstract:

The research presented in this thesis assessed the use of high strength steel (HSS) reinforcement for use in reinforced concrete (RC) bridge columns. HSS is not currently allowed in reinforced concrete bridge columns due to a lack of information on the material characteristics and performance information when used in RC...
