Abstract Viscoelastic (VE) dampers are known to be effective in mitigating structural vibrations of long-period tall buildings. Their dynamic mechanical properties (i.e., damping and stiffness) are highly dependent to the loading frequency and temperature. The co-authors had previously proposed a simplified performance evaluation method for full-scale brace-type VE dampers. However, the VE dampers they evaluated had almost the same ambient temperatures. For this, the authors of this current study conducted low ambient temperature tests and used the results to extend the original performance evaluation method mentioned above to cater wider range of initial temperatures.
