  protection material
The paper considers the geometry of the members, the exposure conditions and the thermal properties of the fire protection material.
      
The degradation in fire resistance is most significant for light-weight columns and for cases where the fire protection material is missing from the flange rather than web.
      
Relatively small proportional losses of fire protection material are required before significant reductions in fire resistance are realized.
      
A finite element heat transfer analysis is used to compare the thermal response of steel columns with lost protection material when exposed to the ASTM E-119 furnace environment.
      
Missing fire protection material on steel structural members is generally recognized as a problem, though little information is available to quantify the effect.
