Tests and Evaluation of Upgraded Flat-Plate and Waffle-Slab Floor Systems

摘要

Several tests were performed at the Waterways Experiment Station (WES) for the Federal Emergency Management Agency (FEMA). The tests were conceived and recommended by Scientific Services Incorporated (SSI) to provide information for use in the Shelter Upgrading Manuals being prepared for FEMA by SSI. The program consisted of tests on individual 19- and 30-inch-square panels taken from waffle slabs, 19-inch panels taken from one-way ribbed joist slabs, two center portions of a waffle slab, and the center portion of a flat plate. Also included, were tests to determine the punching strength of 4-inch-thick basement slabs on grade. These test results will be incorporated into the manuals SSI is preparing on upgrading of shelters.
