To verify the displacement estimation method which is based on the relation between displacement and strain, static and dynamic field test are performed on the real bridge structures. Static and dynamic displacements estimated by using strain signal are well agreed with measured one by LVDT. This study demonstrates that the displacement estimation method using strain signal can be effectively applied to the displacement measurement of bridge structures, which are crossing the river/road/railway or have high clearance.
