![]() ![]() The Australian code now (since 2001 I think) allows the top reinforcement to be concentrated over the column strip for ultimate strength. That is now they do it in their examples.Įngineering logic, statics, equilibrium, load paths and common sense appear to not matter! RE: Requirements of Drop panel in flat slab Ingenuity (Structural) 22 Jun 18 01:32 They are saying that sections including the drop cap are essentially treated as T sections with the drop cap as the web and the full slab width as the flange. It normally only means they are under-designing by about 20% so why worry. It gets even worse when they then use the effective depth of the reinforcement and tendons from the bottom of the drop panel for the "middle strip" reinforcement and tendons (because there are apparently no "middle strips" in PT flat slabs)! Rather than from the bottom of the slab.Īnd then they do the same with the distribution tendons in a slab parallel to a beam as they say that the beam effective widths do not apply either. Unfortunately engineers read this from a "respected" institution and follow their advice.
