Abstract
This paper presents the results of the analytical study of the behavio r up to failure of 74 externally prestressed concrete bridges using a nonlinear finite element model. The aim of the study was to obtain acc urate values of the stress increase of tendons beyond the effective pr estress (Delta f(ps)). A code proposal is derived from the results and is compared with existing current codes.
