Abstract—An analytical method is investigated to identify the damage of a frame structure from static displacement measurements. This method is to adjust the parameters of the frame structure to match the analytical and measured displacements. Based on a set of applied static forces and static displacement measurements of the frame structure, the damage condition of the frame structure can be obtained by optimizing the objective function. In addition, the effect of the number of displacement sensors on the parameter identification was studied using parameter identification of a two-story steel frame structure. This method can accurately identify the damage of the frame structure using limited displacement measurements. 

Index Terms—frame structure, parameter identification, displacement measurement
