Tool bar Stage of construction

Tool bar buttons serve to work with stages of construction. The following picture shows the location of individual buttons:

Tool bar "Stage of construction"

	Adds construction stage	adds new stage of construction at the end of list
	Removes construction stage	removes the last stage of construction from the list
	Construction stage 1,2 ...	switches between individual stages of construction – selection is performed using the left mouse button

In all our programs this bar allows for defining stages of construction. Construction stages serve to model gradual building of a construction (essential for programs Sheeting check, Settlement, FEM). This function can be also used for parametric studies and in each stage of construction assume different soil assignment or different design coefficients. It is rather advantageous to model earthquake effects on a structure in a separate stage of construction as it is then possible to assume different factors of safety or different design coefficients.

For individual types of input (soil assignment, anchors, supports…) there always exists relationship over construction stages (Heredity).
