9 febbraio, Seminario del prof Mario Gustavo Ordaz Schroeder "Models for earthquake loss estimation: construction and applications"

Il 9 febbraio alle 15.00, presso la sala Michelato della sede di Borgo Grotta Gigante, il prof. Mario Gustavo Ordaz Schroeder dell'Università di Mexico City, terrà un seminario dal titolo "Models for earthquake loss estimation: construction and applications".

Il prof Ordaz Schroeder si trova in visita all'OGS nell'ambito di progetti di ricerca sull'hazard sismico.

Il seminario di terrà in lingua inglese e sarà preceduto da una breve presentazione delle attività di OGS, a cura dell'Ufficio Promozione Ricerca.

Abstract

The general approach to build earthquake loss estimation models is presented. The approach is designed for insurance purposes, in order to compute pure premiums and probable maximum losses in portfolios of buildings. Some of its main features are the following:
1) Earthquake motions are characterized in terms of acceleration response spectra, so both intensity and frequency content are accounted for.
2) Response spectrum transfer functions are used to compute response spectra that include site effects.
3) The approach uses displacement-based vulnerability functions to estimate the damage ratio from the maximum inter-story drift. Based on this inter-story drift, a probability density function is obtained to compute the expected annual loss and the probable maximum loss of the structure
Application examples will be presented, as well as extensions for other perils.
