Abstract In recent years, demand for large logistics facilities is rising under the influence of expansion of retail chain development and online market. Most of these facilities are low- and middle-rise steel structures, and it is vital that these structures are earthquake resistant. An energy-based method for earthquake-induced response of a building is very useful for the evaluation of the cumulative damage of structures. However, this method is not applied to structures with uneven stiffness distribution in the height direction like large logistics facilities. In this paper, we analyze whether this method can be expanded to such structures by comparing cumulative damage distribution predicted using this method and calculated by time-history analysis. Moreover, the effect of difference in strength calculation on cumulative damage distribution prediction is examined.
