Erection tower temporary supports provide a vertical reaction load path to the ground. Strong back temporary supports connect adjacent segments.

‍NOTE: Erection towers provid a vertical load path to the ground for both tension and compression forces. When post-tensioning is applied, the girder may have the tendency to "lift off" the erection tower. A hold down (tension) reaction will be producted in the erection tower. Review the erection tower reactions and make sure they are removed at the appropriate stage in the construction timeline.

‍NOTE: Strong back temporary supports are essentially hinges. Be sure your model is geometrically stable.

If segments are connected at this temporary support, then haunch depths and elevation adjustment define the elevation of the support at the time of erection of the first supported girder.
