Studies on Response Control Technologies for Building Structures (1 Vibration Tests of the Large Damping Structures)

摘要

The "STRUCTUAL RESPONSE CONTROL DESIGN" herein described is anew practical technology which realizes structures having artificial large damping by the "Viscous Damping Wall(in brief VDW)". The VDW is a wall- shaped viscous energy dissipator consisting of a pair of vertical steel plates filled with high viscous fluid. This part reports the results of vibration tests in order to grasp the dynamic characteristics of a 4-story full scale steel model with/without VDWs. In the results, VDWs work as the response acceleration and displacement of the model is reduced to 1/2～1/3, if compare to non - attached ones. The 2nd. mode and higher ones completely disappeared in VDW model. It is necessary to consider increase of structual stiffness due to VDWs.
