Title: Experimental Study of Recovered Properties of Retrofit (Repaired) Concrete Members

Publication: Special Publication

Abstract:Two interior column (RC)-beam (PPC) specimens were tested. The specimens were first subjected to reversed, repeated cyclic loading to maximum rotational angles of 1/30 and 1/16, respectively. The specimens were then repaired using resin injection and mortar covering. Mechanical properties obtained following repair were almost the same as those obtained during the initial loading, probably, due to the confined concrete used in the beam ends. However, a reduction in initial stiffness of approximately 30% was observed.
