- Abstract
- The subject of this report is a floor and ceiling assembly which was constructed as shown on Ill. 1. The floor consisted of sand-gravel concrete, 2-1/2 in. thick, poured over a blend of nominally 1-1/2 in. deep cellular and fluted steel form units which were supported near the center line of the assembly by a steel beam. An 18-in. wide trench header and a 6-1/2 in. wide header duct wereincluded in the floor. The exposed steel surfaces were protected with sprayed fiber.
