In order to propose vibration evaluation method of floor response of adjacent building of external vibration source like vehicle vibration, vibration of floor response is measured in the adjacent building of large scale shaking table facility of Kajima technical research institute during it is in operation. Through the measured results and their simulation analysis, vibration translation characteristics from source through soil, building foundation and structure skeleton to floor are discussed. As the results, following conclusions are obtained : (1) Vibration propagation characteristics from source through soil to building foundation are follwed by 2-dimensional finite element method as practical vibration evaluation level. (2) Vibration propagation characteristics from building foundation through structure skeleton to floor are followed by 3-dimensional finite element method as practical vibration evaluation level. (3) In order to express measured results in high accuracy, detailed adjustment is required for analysis model.
