DESIGN OF REINFORCED CONCRETE SLABS EXPOSED TO NATURAL FIRES
Degree GrantorUniversity of Canterbury
The use of prescribed solutions for fire design has allowed engineers to simply provide an assembly of elements which meets a building codes required fire resistance without necessarily understanding or evaluating the development of a fire in a compartment, the corresponding temperatures reached and the implications of such temperatures. A process is presented which uses simple thermal and mechanical models to determine the fire resistance of simply supported reinforced solid concrete slabs. The calculated fire resistance is compared to prescribed provisions for slabs exposed to the standard fire and an equivalent fire severity method for slabs exposed natural fires.
