Deriving target reliabilities from the LQI

A simple way to ensure cost efficiency during code-making or the probabilistic design of individual structures is to make use of the tentative target reliabilities provided in the JCSS Probabilistic Model Code. An acceptable level of life safety is, however, not guaranteed when relying on the JCSS target reliabilities, which have been derived based on monetary optimization. The goal of the present paper is to derive minimum target reliabilities from the Life Quality Index (LQI) that may be used in combination with the JCSS target …
