I'm happy to announce that my research article, titled "Epistemic Uncertainties in Torque Capacity Prediction Models for Circular CFDST Members," has been published in Elservier's Q1 Journal of Constructional Steel Research!
This work delves into the critical analysis of epistemic uncertainties in torque capacity prediction models for concrete-filled double-skin tubular (CFDST) members, with a particular focus on models proposed by Huang (2013) and Lu (2022). The study identifies variability and bias in these models, highlights their statistical characteristics, and emphasizes the necessity for recalibration—especially for high-strength materials.
Key highlights of this study:
1) Comprehensive evaluation of model uncertainty using full and filtered databases.
2) Statistical characterization to improve prediction accuracy and reliability.
3) Proposals for recalibrated partial resistance factors for structural design.
This research aims to enhance the reliability and safety of CFDST structures under torsion, contributing to advancements in structural engineering practices.
A big thank you to my co-authors and collaborators for their invaluable contributions!
