Abstract

This paper presents a simplified and practically applicable approach for risk based inspection planning of fatigue sensitive structural details in steel structures. The basic idea is that the fatigue sensitive details are categorized according to their Fatigue Design Factor (FDF) and SN curve. When a measure of the structural redundancy and the corresponding probability of total structural failure given fatigue failure of the considered detail is known, it is possible to formulate a generic description of fatigue sensitive structural details and thereby develop pre-made inspection plans in tables which depend on relative cost of inspections, repairs and failures.
