As the most critical force transmitting and bearing components of arch bridges, the hanger is also the weakest link of the bridge. Damage to the hanger leads to a redistribution of the internal forces and potentially even the collapse of the bridge. Therefore, this paper proposes a new damage detection method for hangers. Based on the principle of superposition, the relationship between the static deflection change and cable force is studied. Then, a new index is proposed for identifying the damage to arch bridge hangers. Numerical and laboratory investigations demonstrate that this method can successfully locate damage regardless of its location; moreover, the degree of damage can be relatively quantified. In addition, the method is easy to operate and suitable for practical engineering applications.
