Superior design solutions (SDSs) of seven-story steel buildings are obtained for a space frame system (SFS) and perimeter frame systems (PFS) in various structural systems such as moment frame (MF) and those with buckling restrained braces (BRBF). The SDSs satisfy the design constraints of allowable stress design (ASD) and calculations of resistance and limit state (CRLS) with the minimized steel volume. The influences of design conditions are comparatively evaluated. It is found that the maximum inter-story drift ratio for safety limit in CRLS for MF can be rationally defined as 2% and ASD can be more dominant for BRBF.
