System of partial safety factors in reliability-based bridge assessment

초록

A study for developing a new assessment code for concrete bridges has been being carried out in Korea based on the reliability approach. One of the key issues in the assessment code is to stablish a system for determining the partial safety factors for resistances and load effects. The paper investigates the definitions and effects of those factors available in various codes of different countries and proposes a reasonable format for Korean assessment code. The factors are defined according to the target reliability index in the current context of the study. A simulation study is presented to evaluate the effects of those partial factors.
