Martins, A.D., Teixeira, A.P., Ramôa Correia, J. and Silvestre, N. (2023), Reliability-based code calibration for pultruded GFRP I and H-Section columns prone to local buckling, 9th International Conference on Thin-Walled Structures (ICTWS2023), 29 Nov. – 1 Dec., Sydney, Australia
This work presents and discusses a reliability-based code calibration (RBCC) procedure for the determination of (optimum) partial safety factors to be employed in the semi-probabilistic design rules of pultruded GFRP (pGFRP) columns, susceptible to local buckling, considered in CEN/TS 19101: Design of Fibre-Polymer Composite Structures. First, the description of the two distinct resistance models for local buckling of I and Hsection columns adopted in CEN/TS 19101 is presented. Next, attention is turned to the detailed presentation of the procedure to perform a RBCC, including all the relevant data, with emphasis to all the probabilistic models adopted. Next, the results obtained by applying the RBCC procedure are presented and discussed. Lastly, the paper closes with the presentation of relevant concluding remarks and recommends the partial safety factors for I and H-section pGFRP columns susceptible to local buckling (web- and flange-triggered).
