Fire Test of Steel Columns Encased with Gypsum Lath and Plaster
The results presented are derived from fire-endurance tests of 16 steel columns encased with gypsum lath and gypsum plasters. The laths were wired into place; eight columns were of the 3/8-in. thick perforated type in a single layer, seven were of two layers of the 1/2-in. thick plain type, and one a single layer. Six of the latter eight had a layer of wire fabric to reinforce the plaster. Expanded perlite was used as the plaster aggregate for 13 columns, sand for two, and vermiculite for one. The thickness of the plasters ranged from 1/2 in. to 2 in. and those of the encasements from 7/8 in. to 2 1/2 in. The fire-resistance values obtained varied with composition, reinforcement, and thickness of the protective coverings, and to some degree with size of column.
