This paper proposes the application of simplified simulation models without time history analyses to the approximate estimation of life-cycle cost in the seismic risk management of a building. The simple models are utilized to simulate the related processes, i.e., fault rupture, elastic wave propagation in rock, surface soil amplification, dynamic response of a building, and generation of damage costs. In the presented case study, as simple but well-developed models, the author select an attenuation relationship of response spectra that can consider local site effects for ground motions, the Capacity Spectrum method to obtain structural response, and fragility curves for the estimation of damage costs. The life-cycle cost estimated using such simple models is demonstrated to exhibit a good agreement with the result obtained form more sophisticated simulations involving time history analyses, which was conducted in the past study. It is concluded that appropriate simplified simulation models can promptly and cheaply provide an owner of a building with the rational decision-making in the seismic risk management of a building.
