A new method for earthquake strengthening of old R/C structures without the use of conventional reinforcement
Alexander-Dimitrios G. Tsonos

 
Abstract     [Full Text]
    In this study an innovative method of earthquake-resistant strengthening of reinforced concrete structures is presented for the first time. Strengthening according to this new method consists of the construction of steel fiber high-strength concrete jackets without conventional reinforcement which is usually applied in the construction of conventional reinforced concrete jackets (i.e., longitudinal reinforcement, stirrups, hoops). The proposed in this study innovative steel fiber high-strength or ultra highstrength concrete jackets were proved to be much more effective than the reinforced concrete jackets and the FRP-jackets when used for the earthquake-resistant strengthening of reinforced concrete structural members.
 
Key Words
    steel fiber high-strength concrete; reinforced concrete jackets; beam-column joints; columns; cyclic loads
