| Abstract: | The effects of the plate thickness, strength of concrete and anchor measurements on the fatigue property and the mechanic properties based on the static tests of reinforced concrete beams strengthened by steel plates are compared, and modes of failure are summed up. The load deflection curves of beams and load displacement curves of beams based on the fatigue experiments of plated and unplated RC beams are presented. The differences of mechanic performance between anchored and unanchored plates are also compared according to the distribution of plate strain. |
