Repair and strengthening practice is based mainly on intuition, and reliable experimental data available on the repaired/strengthened reinforced concrete structural member behavior are very limited. However, the subject has recently started to receive researchers' attention, and a few experimental studies are being carried out in various European and North American countries. Current research activities in this field at the Middle East Technical University and Gazi University, Ankara, Turkey, are briefly introduced. The projects reviewed are: 1) jacketed column behavior under uniaxial load or combined axial load and reversed cyclic bending; 2) behavior of beams strengthened for flexure under monotonic, repeated, and reversed cyclic loading as well as beam strengthening by epoxy glued steel plates; 3) slab repair and strengthening; 4) system behavior improvement by introducing either cast-in-place reinforced concrete infills or masonry infills; 5) epoxy anchorage of new steel into the existing concrete. Results obtained from the test series already completed are briefly reported, and the other series in progress are briefly introduced.
