Identification of the Mechanisms that Produce Hydrogen Embrittlement on Post-tensioning Members and the Effects of Galvanic Coupling on Bridge Tendons

The objective of this work is to identify the possible consequences of having galvanic coupling between the post-tensioning steel and the galvanized ducts in deviators and bulk heads with regards to the evolution of hydrogen on the high strength steel used for post-tensioning.
