Among many viscoelastic dampers, linear ones seem better than nonlinear ones, because it is quite easy to simulate linear behaviors by making use of a simple generalized Maxwell model. However, their mechanical properties are usually quite sensitive to environmental temperature. To get rid of this bad influence, we developed a temperature control system for the VED. This paper reports the scale effect of this system. First, by the random wave excitation experiments, the temperature dependent mechanical properties of the full-scale VED were examined. And second, by applying the temperature control system to the damper used for seismic retrofitting of an existing reinforced concrete building, the scale effect of this system was studied. In addition, the influence of the VED on dynamic characteristics was examined by means of the dynamic loading test on the full-scale damper that includes this system.
