Recent building structures are superior in its ability but they are light and flexible, and so have problems of habitability induced by building vibration. In general, the problem of vertical vibration is not considered in structural design. However, in terms of serviceability for inhabitants in buildings, the estimation of vertical vibration in design stage is important. Characteristics of vertical vibration is changed by modeling method of beam-column joint. To check the characteristics of vertical vibration, many tests and analyses were conducted on constructing building in Seoul. Results of tests and analyses were compared using transfer function. As a results, to check the vertical vibration characteristics, the cramp ratio of beam-column joint must be considered and reduced to 50% ~ 60% in structural design.
