Abstract

For the preliminary decision-making in the seismic risk management of buildings, we developed a computer program to evaluate the expected lifecycle cost (LCC) without time history response analysis. The methodology employs the Capacity Spectrum method to estimate peak building response in the scenario analysis for the events from a fault rupture to damage costs. For the LCC estimation, the program is equipped with the database of the seismic sources all over Japan. Then the program can compute the LCC by combining the probability models for earthquake occurrences and the deterministic losses from selected fault ruptures, which are obtained by the scenario analysis.
