Repair of reinforced concrete column by plastic hinge relocation

Repair of reinforced concrete bridge column by plastic hinge relocation.

This analysis aims to challenge the idea that bridge columns containing buckled and fracture reinforcing bars don't seem to be economically serviceable. Through testing and analysis, the analysis is developing a series of techniques that use plastic hinge relocation for fast repair of columns broken in associate degree earthquake.

This analysis conducted to develop a brand new affiliation between substructure and structure that consisted of grout and shear studs.

This bridge column was broken with a second simulated seismal load so repaired mistreatment plastic hinge relocation. Note the steel shell round the base, that surrounds high strength grout and 1.25" diameter steel reinforcing bars that were dowelled and epoxied into the footing.
