Abstract: Current design codes are based on a semi-probabilistic approach which requires calibrated partial factors to secure the safety of structures and people. The current code calibration procedures do not reflect the development of computation tools and improved knowledge of structural design. Moreover, the current procedure neglects economic aspects which should be an integral part of any code calibration. This article presents a modified approach of the reliability-based code calibration applied to UHPFRC thin elements predominantly loaded in bending. The modified approach eliminates disadvantages of the original procedure and it is defined in a way to take advantage of the current computation means such as parallel and cloud computing. Moreover, the removal of the iterative loop allows using Monte Carlo methods (among other options) which are normally time-consuming and impractical for code calibration. The new design verification of UHPFRC with the newly calibrated partial factors allows better exploitation of the material without compromising the safety requirements.
