ABSTRACT
ABSTRACT: This work is a study of the structural answer of cable stayed bridges when the sudden loss of one of their stays takes place. The analysis has been accomplished through two different methods: by means of a dynamic analysis and carrying out a procedure, included in the P.T.I. (2000) and S.E.T.R.A. (2001) recommendations, which consists of developing a static analysis in which the dynamic action is replaced by a static force increased through a dynamic amplification factor. The different results of bending moments in deck and pylons and tension force in stays obtained by these two methods are compared and analysed.
