A wire bolt comprising an elongated section of wire rope with a section of threaded stud attached to each end is disclosed for use in reinforcing concrete structures. Part of the wire rope portion is coated with a substance to prevent that portion from bonding with the concrete. The threaded rod portion can be attached within the concrete by epoxy or attached to the concrete by appropriate mechanical means. The wire bolt can be attached to a concrete building structure during initial construction of a structure or retrofit into existing structures. Wire bolts should be installed in areas susceptible to shear or bending failure and serve to prevent the concrete sections from separating in a seismic event.
