A seismic repair cost in a building stems from the damage of nonstructural components as well as structural members. If nonstructural elements were not adequately designed, sometimes the repair cost for nonstructural components may exceed the repair cost for structural members. To simulate these damages and repairing process, a building structure is modeled as a simple system of multiple masses and shear springs with non-linear hysteresis model, and nonstructural components are classified into inter-story-drift-sensitive components and peak-floor-acceleration-sensitive components. To consider the occurrence of multiple earthquakes in high seismic zone, life cycle earthquake scenarios are assumed. And then the accumulated repair costs in life cycle are evaluated. It is revealed that the increase of ductility capacity of the structural system changes the nonstructural repair cost. It is also revealed that the ratio of the repair cost for nonstructural components to the total repair cost is depending on the life cycle earthquake scenarios in spite of the same life length.
