Fire proofing

Fire proofing is the application of fire resistance material on the surface of structural members in the form of:

protective paints
thin/thick film coating
sprays
fire boards

In Tekla Structural Designer fire proofing can be applied as a surface coat to members, defined by a thickness and density.

Note: Fire proofing can be applied to all 1D member types apart from analysis elements, DELTABEAM, and FABSEC beams.

The additional self weight of fire protection material is then added to the "Self-weight - excluding slabs" loadcase.

Note: If Calc Automatically is unselected for the "Self-weight - excluding slabs" in the Loading dialog, neither the member self weight, or the fire proofing self weight are calculated.

The extra thickness also increases the area exposed to wind if open structure wind loads are applied to the member.

How to apply fire proofing

Fireproofing is applied to a member by selecting ‘Protected’ under the 'Fire proofing' heading in the member properties. It can also be applied graphically using the Fire proofing attribute in Show/Alter state.
