Finite Element Model(FEM) is generally used for evaluating a bridge construction. But it has discrepancy between measured data of real structure and analysis value of FEM. Therefore, FEM has to reflect characteristics of real structure using FEM updating. Static and dynamic data used to FEM updating update different characteristic of FEM. However, since it is difficult to measure static data, static information extracted from dynamic measured data can be used. In this study, new concept, LDFAC, using Lateral Distribution Factor(LDF) extracted from dynamic data is introduced as static information. As the analysis results, it is verified to get more accurate updating value when updating FEM with LDFAC.
