Fire load group

For fire design situation, a dedicated Fire load group was created that handle the specialties of fire effect. Before specifying the fire effect, a fire load group and at least one fire load case must be defined.

Fire load group has more options:

• Analysis with room temperature material properties - this calculation method must be chosen to check the structure with reactive protection (intumescent paint).

• Analysis with elevated temperature material properties - for the check of structures with passive protection (e.g. gypsum insulation) or without any protection. The stresses and displacements are determined based on the required fire resistance time.

  • Consider indirect actions caused by thermal expansion: By default Consteel neglect the effect of thermal expansion during the analysis, but by clicking on the checkbox there is the possibility to take it into account.

• Value of variable factor for main variable load: By default, Consteel applies the Ψ2,1 but switching the radio button Ψ1,1 also can be used for load combination generation.

At least one load case must be added to the fire load group to place the fire effect on the model.
