000010707 520__ $$2eng$$aThe Japanese seismic design code adopts a factor Ds for chevron-braced frames to consider the seismic force reduction due to the ductility. The Ds value varies from 0.25 to 0.5 according to the type of backup frame, the slenderness ratio of braces λ and the participation ratio β of braces. The selection of Ds in the design process is deemed rather complex. This study examines the ductility of some representative multi-story braced frames designed with different Ds , λ and β , and finds that the braced frames have a smaller deformation than the pure moment frames with the same Ds value. It is possible to use a unique value of Ds for braced frames.
