Test and Analysis of Upgraded One-Way Reinforced Concrete Floor Slabs.

Abstract

The problem of upgrading one-way reinforced concrete (R/C) slab floor systems for keyworker shelters was studied in this program. The objective was to develop competent designs for upgrading such systems that would use readily available materials, be easy to construct, and increase the load-carrying capacities of such systems to 50 psi or greater. Two upgrading methods were developed and evaluated: a wooden post method and a steel beam method. For the wooden post method, several 4- by 4-inch timbers were placed in groups under the midspan of the slabs. These groups acted as units to form columns large enough to accept large loads and provide sufficient bearing area. For the steel beam method, the floor slab panels were supported at midspan with a series of small steel beams held up by steel pipe columns. The components were kept small enough so two or three people could handle them. The existing beams of the floor systems were upgraded with additional posts in both methods.
