Reliability analysis of pet strap pullout models

This paper shows the statistics on the Polyester (PET) strap pullout model's accuracy. An empirical modification method to improve accuracy is proposed for the existing models. A new non-linear model is also presented, with the best accuracy based on bias values' mean, coefficient of variation (COV), and dependency with predicted pullout capacity (ρ) and test conditions. This study contributes to pullout limit state assessments using deterministic or reliability-based analysis and design approaches.
