Assign load cases

In the Load Cases sub- tab of the 'Construction stages' tab, you can assign the relevant load cases to the construction stages.

Important

You do not need to define a load case for each construction stage: The loads of a load case are only taken into account for the structural objects that are active in the current construction stage!

To Assign

When you first open the tab, all load cases are listed for construction stage BZ1 that you have defined in the 'Load cases' tab. You can now assign the load cases to each construction stage, which will act on the structural objects from this point in time onwards. For example, if you set the load case 'Self-weight' in construction stage BZ2, this load case is no longer available for the following construction stages: It is already taken into account. The dead loads of the structural objects that are activated in the following construction stages are applied automatically.

As usual, you can assign the selected load cases individually to a construction stage with the Add button. The load case type is used to decide whether the load case is assigned as 'Permanently' or ' Not always '.

With the button Add Items as "Permanent" you can assign the selected load case manually as 'Permanent ', with the button Add Items as "Non-Permanent" as' Not always '.

Assigned Objects

This table shows all load cases that are effective in the selected construction stage.

State

The status shows whether the load case is 'Active' for the selected construction stage. If you remove a load case with the Remove button, it is marked as 'Inactive' for this and the following construction stages.

Active

This column indicates in which construction stage the load case was activated for the first time.

Inactive

This column appears if you have deactivated a load case again. Here it is indicated from which stage of construction this load case is no longer effective.

Permanent

The check box in this column indicates whether a load case 'Constantly' or 'Not always' is effective. Constantly acting load cases are impressed in the system; their influence (stresses and strains) are transferred to the following construction stages. Load cases that do not act continuously are only applied in the construction stage to which they have been assigned.

Factor

In this column you can specify the load factor with which the loads of the load case are to be taken into account for the construction stage calculation.

You can also consider

Info

load factors - for example 1.35 for a permanent load - at a later point in time when you combine construction stages .
