Structural elements supporting fire barriers

Discussion created by krousea on Aug 29, 2016

If a 1-hr shaft is constructed in a type II (000) construction type building, 3 stories, and the fire barrier wall construction bears on the 2nd a 3rd floors, to what extent does the structural steel (columns, beams, and girders) supporting the floor construction need to be fire resistance rated? e.g. spray on fireproofing.

 

Is the intent of the Life Safety Code to have exit enclosures and HVAC shaft enclosures be self supporting?
