Analytical modeling of square and rectangular concrete sections confined by FRP: ultimate strength prediction

ABSTRACT

An analytical model tailored for the ultimate stress prediction of the FRP confined concrete section is presented. The model has been conceived to be implemented in a design code and a simple yet robust mechanics-based equation has been developed and tested against a set of experimental literature data. The model is thought for square/rectangular sections and considers the corner radius influence, so that circular sections are automatically included as a particular case.
