000011430 520__ $$2eng$$aSeismic damage assessment of structures was highly emphasized in earthquake engineering. More extensive attentions were being placed to the influence of near-field ground motions on structures, the notable long-period velocity pulse feature of near-field ground shaking would cause the structures into severe damage, and lead to shocking economic losses and casualties. Furthermore, the economical and practical buckling restrained braces can reduce the structures response effectively, avoiding unnecessary economic losses and death. Considering many uncertain factors and incontrollable conditions of the damage index, the conception of fuzzy sets and fuzzy membership is used in this paper. In order to compare, two damage assessment procedures are presented with different border points values. Regarding holistic damage index, storey damage index, storey drift ratio and number of inelastic cycles which indicates the cumulative loss of energy, the multiple fuzzy seismic damage of high-rise steel frame structure with buckling restrained braces is evaluated based on fuzzy mathematics theory, which makes the structural seismic safety assessment scientifically meaningful.
