Fireball Tests of Open Web Steel Joists

T. E. Waterman

As a result of fire tests conducted for GSA in 1973, a potential problem of protection for lightweight steel joists used to support the roofs at GSA records centers was investigated. The problem was that exposure of unprotected roof support members to a fire might cause the steel roof supports to sag to the extent of collapsing the sprinkler piping and rendering the fire protection system inoperative. Several tests on various typical bar joist configurations were conducted to determine how best to provide a small time segment of protection to the steel. The criteria was to find materials that when applied to the steel and subjected to severe fire temperatures, would prevent the rise in temperature to the steel to above 1100 F.
