The superimposed dead load (SDL) is 1. 0 Cantilevers 10. When the beam bends, a part of the slab also bends along with the beam. Molin also offers precast lintel beams in 7-5/8 inch and 11-5/8 inch nominal widths that range from 8″ to 40″ in depth. His logic is that continuous beam predicts less deflection ( and hence gives more economical design), is his claim valid? I wonder how does practicing engineers view the modelling and analyzing/designing beam spans as continuous beams ( instead of beams with many supports) when it comes to reinforced concrete building structures? Do they. 00 ft Effective haunch depth, Heff = 0. The footing sizes on these charts are only recommendations, and ideal footing sizes can vary between different locations with similar soils and even slightly different building materials.
