Coefficient Method For Slab Design . Analysis by the coefficient method while it was not a part of the 1977 or later aci codes, its continued use is permissible under the current code provision (aci code 13.5.1) that a slab system may be designed by any procedure satisfying conditions equilibrium and geometric compatibility, if it shown that the design strength at every section is. W u = 1.2*dl+1.6*ll where dl= total dead load (i.e.:

The expressions for moment take the form of coefficient multiplied by total factored load per unit length on the span & the length of the clear span. I couldn't find any references/books explaining further about this method unlike ddm or efm method which are always found on most modern reinforced concrete design books. It also demonstrates the d. The thickness of a floor slab must be determined early in design because the weight of the slab is an important part of the dead load of the structure.

Therefore span ratio m = 13/19 = 0.68. These coefficients are based on elastic analysis but also account for inelastic redistribution. Moment coefficients method is a very restricted method but as itβs rather simple to use, it has been mostly applied in analysis and design of concrete slabs.
