Abstract:
This paper discusses camber control in segmental precast prestressed concrete cable stayed bridges. The prototype bridge structure consisting of three continuous spans is analyzed both during erection and service stages. The method of predicting the initial camber during erection and calculation of the required pre-tensioning forces in the cable stays to produce this camber are discussed. A numerical example analysing deflections for a typical segmental prestressed concrete bridge is presented.
