The feasibility of using viscoelastic (VE) dampers to mitigate earthquake‐induced structural response is studied in this paper. The properties of VE dampers are briefly described. A procedure for evaluating the VE damping effect when added to a structure is proposed in which the damping effect of VE dampers is incorporated into modal damping ratios through an energy approach. Computer simulation of the damped response of a multi‐storey steel frame structure shows significant reduction in floor displacement levels.
