Using an image analysis method, the deformation behaviors of RC beams with artificial damage were investigated under a moving wheel load condition. The two beams were loaded simultaneously with a moving wheel under dry and wet surface condition, respectively. This study focused on the maximum principal strain and maximum shear strain of the beam with wet surface condition. Analytical results clearly showed that the deformation behaviors in the upper part of the specimen were affected by wheel load positions.
