Reliability Analysis of Static Equilibrium
Original language description
Limit state of static equilibrium is an essential ultimate limit state to be verified in persistent and transient design situations of construction works. In the present study the static equilibrium of a cantilevered beam and motorway gantry is analyzedconsidering traditional probabilistic models for permanent and variable actions. It is shown that the alternative sets of partial factors recommended in EN 1990 for stabilizing and destabilizing action effects lead to different and mostly insufficient reliability levels (reliability index around 3). Span ratios and correlation between favourable and unfavourable permanent actions influence predicted reliability levels. With increasing correlation the reliability increases. More conservative factors thanthose recommended in EN 1990 are proposed for verification of common structures by the partial factor method. For verification of important and costly structures, application of probabilistic reliability analysis is advised.
