Cable-stayed bridges are modem solutions offering important advantages: the possibility to cover large spans and through this reducing the number of substructure elements,a relative small construction depth,a good esthetic.In the design stage of such type of bridge,several parameters concerning the bridge geometry are to be considered: span length,height of the pylons,the number and distribution of stays along the bridge deck.From these,the number and position of stays plays a very important role from possible further strengthening point of view.A large number of stays together with an optimized distribution can lead to major advantages,if stays damages occur or if the strengthening of bridge is necessary in order to fulfill the new traffic requirements.
