BRIDGE EVALUATION TECHNIQUES BY PARTIAL RELIABILITY GRITERÍA. CASE STUDY: A PRESTRESSED CONCRETE BRIDGE

Edgar Muñoz, Jorge Alonso Prieto, Nelson Abragon

Abstract


Structural safety analyses based on reliability provide a direct link with risk evaluation and economic decision. The term "partial reliability" allows for actual conditions ofthe state ofa civil work, e.g. degradation, deficiency, failure, etc, and actual traffic loads, but it does not include earthquake, wind, flood or scour effects. The model developed in this paper is a combination of Structural analysis based on discrete finite elements and Montecarlo simulation techniques using Matlab® software.
