Abstract
Three reinforced concrete columns with inadequate strength, non-contact, lap splices at their base were tested to failure under reversed cyclic loading. An investigation was then made of a method for jacketing such damaged columns in order to reinstate and improve their seismic performance. The damaged columns were jacketed using a steel fiber mat infiltrated with slurry and then again tested to failure under reversed cyclic loading. Details are provided of the seismic performance characteristics of the columns, and the repair techniques used.
