This work presents a reliability analysis of shear-capacity predictions, organizing 142 high-strength (HSFRC) and 265 normal-strength (NSFRC) beams and evaluating how shear design models behave under uncertainty. It tests the adequacy of the standard Gaussian assumption and proposes Lognormal and Weibull alternatives. Using FORM and SORM across dead, live, snow, wind and seismic loads, it compares empirical, semi-empirical and machine-learning formulas, analyzes risk-level resistance coefficients, and finds traditional equations often conservative while ML formulas offer better prediction, with reliability balanced against safety and cost.","University of Birmingham  \nMachine Learning and Traditional Approaches in Shear Reliability of Steel Fiber Reinforced Concrete Beams  \nQin, Xia; Kaewunruen, Sakdirat  \nDOI:  \n10.1016/j.ress.2024.110339  \nLicense:  \nCreative Commons: Attribution (CC BY)  \nDocument Version  \nPublisher's PDF, also known as Version of record  \nCitation for published version (Harvard):  \nQin, X & Kaewunruen, S 2024, 'Machine Learning and Traditional Approaches in Shear Reliability of Steel Fiber Reinforced Concrete Beams', Reliability Engineering and System Safety, vol. 251, 110339.

This study pioneers a novel reliability analysis of shear capacity predictions for SFRC beams, distinctively classifying the datasets into high-strength (HSFRC) and normal-strength (NSFRC) categories. A comprehensive database of 142 HSFRC and 265 NSFRC beams serves as the foundation for this analysis, which critically examines the standard Gaussian distribution in shear design models and proposes the Lognormal and Weibull distributions as more precise alternatives. Employing advanced First-order (FORM) and Second-order Reliability Methods (SORM), the study covers a broad spectrum of load conditions, including dead, live, snow, wind, and seismic loads, to evaluate various empirical, semi-empirical and machine learning proposed shear capacity prediction formulas. One of the key innovations of this research is the development of differentiated resistance coefficients for
