Construction stages setup

The Setup dialogue for Construction stages enables you to input the default values of the parameters that appear in the input dialogues for individual construction stages.

Load factors

Permanent (long-term) load case

Gamma min Gamma max are attached to permanent load cases of both types – load (gG) and prestress (gP). The load factors gGmin(<=1), gGmax(>=1), gPmin(<=1), gPmax(>=1) are specified (for each load case) in each construction (or service) stage. If long-term variable load is selected in the combo box Permanent or long-term loads, only maximum factor gQmax is asked, because gQmin is automatically taken as zero (when all variable load is removed). At the same time additional factor y<1 will appear.

Prestressed load case

See above.

Long-term part of variable load

Factor y specifies the long-term part of the load. If the dead, prestressing or variable LC is applied in a construction stage, it can never be applied again (exclusivity), because the configuration of the structure could be changed in next construction steps and the results would be different.

Results

Name of generated ultimate combination (max)

Specifies the mask for the automatic generation of names of maximal load case combinations.

Name of generated ultimate combination (min)

Specifies the mask for the automatic generation of names of minimal load case combinations.

Name of generated serviceability combination

Specifies the mask for the automatic generation of names of serviceability load case combinations.

Note: Concerning the generated names of load case combinations, the sequence {O} is substituted with the appropriate number during the generation of the combinations. For example, the combination name mask F{O}-MAX gives combinations named F1-MAX, F2-MAX, F3-MAX, etc.

Note: This very same dialogue may also contain parameters for TDA. These TDA parameters are available only in a project that supports time dependent analysis. See also TDA setup.

Procedure to adjust Construction stages parameters

  1. Open the service Construction stages.

  2. Start function Setup.

  3. Input the required parameters.

  4. Confirm with [OK].

  5. Close the Setup dialogue.
