Abstract
An analytical model is proposed for the prediction of ultimate strength of square sections confined by FRP. Since the model considers the corner radius influence, circular sections are automatically included as a particular case. The simplified model has been tested against a set of experimental values available in the literature: the comparison was satisfactory and its accuracy is discussed. The performance of the model is validated in terms of average absolute error and its standard deviation. The model is based on a revision of the classical strength criterion proposed by Ottosen.| File | Dimensione | Formato | |
