CONSECUTIVE ESTIMATION OF VIBRATION CHARACTERISTICS CHANGES OF TWO-STORIES STEEL FRAME HOUSE CONSIDERING NON-STRUCTURAL ELEMENTS CONSTRUCTION PROCESS

In this study, changes in vibration characteristics during the construction of a two-stories steel frame house were examined. During the interior construction period, consecutive vibration measurements were conducted in daily construction process. The influence of non-structural elements construction work was observed on the change in vibration characteristics. As a result, it was confirmed that plasterboard and partition wall substrate, putty filling for inner wall or partition wall increased stiffness and viscous damping coefficient. Furthermore, it was found that plasterboard for inner walls mainly contributes to increasing stiffness, while putty filling mainly contributes to increasing damping.
