One reference is Timoshenko and Goodier's "Theory of Elasticity". Summaries of this concept are given in concrete texts such as MacGregor's "Reinforced Concrete Mechanics and Design" or Wang and Salmon's "Reinforced Concrete Design". See also ACI 318 commentary sections R10.2.6 and R10.2.7, it's a similar concept.

Does any one know any reference that addresses the basic source of the effective width of T & L sections in the ACI 318?
