ABSTRACT
These drawbacks appear to be overcome by the design procedure proposed in [3] for dual eccentrically braced structures. The procedure is founded on the overstrength factor of links and on the damage distribution capacity factor of the single story [4]. Owing to the dependency on local parameters, this procedure can ensure design objectives which are more stringent than those usually considered by modern seismic codes. In particular, the seismic response is expected to be characterized by fairly uniform distributions of the link damage and by low sensitivity to realistic variations in the mechanical properties of members and in the dynamic characteristics of ground motions. The design procedure yields good results but is more complex than usual procedures considered in seismic codes.
