The fact findings suggested that the fire resistance for longer and fixed to fixed column were required a new guide line for covering of fire protective materials.
This constructional process was much efficient than other construtional materials.
Therefore, to sustain the same fire resistance for longer H-sections in hinge to hinge, the more fire protective materials are recommended.
