The "Structural Response Control Technology" herein described is a new methodology which realizes structures having. artificial large damping by the "Viscous Damping Wall (in brief VD-Wall)". The VD-Wall is a wall-shaped powerful passive energy dissipator consisting of a pair of vertical steel plates filled with high viscous fluid. This part reports the results of performance tests using full scale VD-Walls conducted to grasp the damping characteristics of VD-Walls. The following facts were revealed; 1) The viscous resistant force Qw generated in the VD-Wall can be represented by the sum of damping force Qd and restoring force Qk(C)w=Qd+Qk). The former Qd is proportional to the velocity gradient (dV/dy) raised to the a power, the latter Qk to the relative displacement(δ) raised to the (1+β) power. 2) The value of exponent α is substantially constant regardless of the viscosity of fluid. And the value of β is also constant regardless of the viscosity. 3) The damping capability of the VD-Wall during out-plane deformation is virtually the same as one when it is not deformed.
