WebMay 11, 2024 · Flat slabs are reinforced concrete slabs supported directly on columns, without beams. They are sometimes thickened at the columns to form column drops. These drops are very effective when the negative moments at supports are quite high or where punching stresses are very critical and punching reinforcement is not desired. WebA direct method for design of slabs, instead of the usual process of trial and analysis, is introduced considering desired behavior and necessary distribution of prestressing in the slabs. Direct design equations are developed, procedure is outlined, and illustrative problems are included. computation of the balanced load list of largest reits
