Calibration of safety factors for prestressed stayed steel columns

Abstract Previous studies have investigated the behaviour of prestressed stayed steel columns with a view to developing design guidelines. As most modern standards move towards calibrated safety factors, there is need explore expectations these structures from probabilistic perspective. This has not been studied in literature till now, perhaps due lack clarity on underlying uncertainties, failure models and reliability levels. In this paper, relevant levels were highlight critical modes for such structures. A sensitivity analysis was performed random variables investigate their impact model output. The found through appropriate then compared target reliabilities calibrate partial factors be used range factor values depending conditions adopted calibration studies.
