Continuous post-tensioned bridges are very efficient structures. By eliminating the need for deck joints, this requires less maintenance, which is a significant saving in the long-term. Precast prestressed concrete (PPC) girder bridges are made continuous by using cast-in-place closure joints combined with continuous draped post-tensioning tendons. The webinar will present the proper modeling of continuous post-tensioned girder bridges utilizing staged construction for the time dependency. And checking the load rating by using the resulting internal forces received from the detailed finite element analysis.
