Friction-dampers have been used for the aseismic design of the headquarters building of the Canadian Space Agency. Three-dimensional nonlinear time-history dynamic analysis was used to determine the seismic response of the structure. Comparison of seismic response with conventional structural systems demonstrated the enhanced performance of a friction-damped structure. The introduction of supplemental damping provided by the friction-dampers eliminated the necessity of dependence on ductility while the structure remained elastic without damage. The chosen structural system provides an economical design solution and significantly increases its damage control potential to safeguard the building and its valuable contents against earthquakes.
