Bridge construction stage analysis using distortions

When the stages construction analysis is necessary?

Civil buildings in which the weight of new levels is applied to the lower ones do not require stages analysis as we can get more accurate displacements only.

Staged construction analysis is important when structural stiffness, element properties, and boundary conditions are modified on different stages; when auxiliary elements are included to or removed from the structure; when some force control procedures are performed.
