In previous publications CINI presented finite element models that simulated the collapse and post-collapse behavior of steel pipes under external pressure and bending. Those finite element models were used to analyze the effect of different imperfections on the collapse pressure and collapse propagation pressure of steel pipes. Laboratory tests were performed on TENARIS seamless steel pipes at CFER (Edmonton, Canada) in order to obtain experimental results that could be used to enhance the reliability of the numerical models. In this paper we compare the numerical and experimental results for the case of external pressure without bending.
