000011114 520__ $$2eng$$aIn microtremor observation, forces are inputted to multipoint of the system. However, input forces cannot be specified. The authors have proposed a new method to estimate Frequency Response Functions, which is a scheme to extract coherent components of the system non-parametrically. This paper presents the availability of the proposed method for applying to microtremor records of an existing bridge. Consider items are as follows. (1)The modal characteristics identified by the proposed method in combination with an experimental modal analysis method, (2)comparison with results of forced vibration tests (FVTs), and (3)comparision with results of eigenvalue analysis of numerical model referred to FVT results.
