抄録

Field observations are carried out on the load distribution by joint in a pipe beam roof which is used for constructing a passage under the Tohoku main line of Japanese National Railways.<br>The field observations are composed of two stages. The strains and the displacements of the pipes are measured under the dead load as well as the moving train load in order to confirm the accuracy of the proposed structural analysis and to examine the impact coefficients for the structure. Then, the natural frequency and the damping ratio are measured by the free vibration test to obtain the fundamental data for the dynamic properties of the structure.
