 Temporary Supports will be removed  Post – Tensioning will be doneġ.  Scaffolding weight and wet concrete weight will be removed. Stage 3 Stage 3:  Deck will be activated by activating part 2 of the composite section. Stage 2 Stage 2:  Construction of Prestressed Beams  Prestressed Girders will be simply supported via temporary supports  Beam End release will be used to simulate the simply supported nature  Activation of end supports  Self weight and prestressing will be considered  Deck will be casted on day 10, so the weight of scaffolding and wet concrete will be activated on day 10 Stage 1 Stage 1:  Construction of Concrete Box Girder  Temporary supports are provided as shown  Concrete Box Girder will be modeled as a grillage model  Self Weight of the Girder and Piers will be activated

 Tendon group is not used to activate or deactivate a tendon, it is just used to see the results of a certain number of tendons together. Groups are important because:  Only the structure groups, load groups or boundary groups can be activated or deactivated in the construction stages, element number or load case name cannot be used to deactivate.
