Strengthening reinforced concrete T connections by steel straps

The aim of this paper is to present results of testing a full scale reinforced concrete T connec-tion by static loading. The connection is a T connection representing a beam-column connection. The beam and column had a square cross section with a 300 mm dimension. The height of the column was 2.9 m and the clear beam length was 1.4 m. The connection was initially tested to failure. Galvanised steel straps were used to strengthen the connection. Epoxy resin was used to fix the steel straps to the concrete surface. The connec-tion was tested after the rehabilitation. Results of testing the rehabilitated connection show that the yield and ultimate loads were 65 kN and 95 kN, respectively, compared with the original test results of 75 kN and 84 kN, respectively.
