Abstract:
A design procedure for slabs subjected to concentrated loads is presented. Current procedures, except for bridge decks, do not specifically treat concen-trated loads. The five-step procedure provides for the actions peculiar to concentrated loads as well as the effects of all loads. Although the ACI requirements are used in illustrations, the procedure is applicable to any similar code. The object of the procedure is to provide positive provisions for the inclusion of the effects of concentrated loads, including column reactions in flat slabs and flat plates. Examples utilize a flat plate subjected to uniform load and a concrete slab on steel beams subjected to fork-lift truck loads.
