- Synopsis
- Seismic risk analysis, enables quantitative evaluation of earthquake damage levels, is an indispensable technique for estimating life cycle cost (LCC) and probable maximum loss (PML) which are important indices for disaster prevention planning and business continuity program (BCP). This paper focused on seismic event risk curve and its integral representation 'seismic risk curve'. Firstly, numerical and graphical definition of the seismic event risk curve and the seismic risk curve are presented. Secondly, several examples of the seismic event risk curves and the seismic risk curves applied to reinforced concrete structures are demonstrated as well as the future prospects.
