Attention is directed to the taller frames with shear-critical links, located in typical eastern and western North-American sites. Design procedures are described and applied to the 14- and 20-storey frames. The importance of different design criteria is discussed and the appropriate design sequence is suggested. It was found that ductility requirements did not control design. The seismic response of the frames was investigated using the non-linear time-history analysis to assess if the design procedures achieved desired frame response. The analyses were done for the sets of earthquake records calibrated to match design spectra at studied locations. The results obtained indicate that structures in Vancouver developed links shear forces and deformations higher than those anticipated in design. In spite of large reserve of strength, limited yielding of braces and columns was also observed. For structures in Montreal all global and local response indicators remained well bellow design limits.
