Fire proofing is the application of fire resistance material on the surface of structural members in the form of:
thin/thick film coating
In Tekla Structural Designer fire proofing can be applied as a surface coat to members, defined by a thickness and density.
The additional self weight of fire protection material is then added to the "Self-weight - excluding slabs" loadcase.
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.
