Bridge damage due to pounding at joint of girders and abutments has been observed in many major earthquakes. However, the studies mainly been numerical and abutment behavior itself was rarely investigated. Very limited experimental investigations were conducted. The objective of this study is to experimentally evaluate the influence of the pounding effect on parapet wall of abutment behavior, especially on the deflection, crack and stress-strain result on parapet wall and steel reinforcement. The collision or pounding load from superstructure is idealized into incremental static horizontal load through its rupture. Results show that crack phenomenon distribute on the bottom of parapet wall, which propagate along the width of this structure. It leads the wider crack width along this parapet wall. The maximum horizontal deflection at top of this wall is 25.24 mm. In addition, the strain at the maximum crack reach the ultimate value of concrete strain, which prove by the result of developed crack, further weakening and leading to failure of the parapet wall. © 2018 IAEME Publication.
