Creep of cracked reinforced beam
Conventional cracked reinforced concrete beam theory is extended to include general linear viscoelastic behavior of matrix (concrete) material in compression; analytical formulation is developed which leads to single governing equation on position of neutral axis; although it has not been possible to obtain general closed solution, some important properties of solution of this nonlinear Volterra-type integral equation are established; relationship of this theory to popular approximate procedure, known as effective modulus method, is discussed; nonlinear integral equation is resolved numerically, and results are shown for several cases of interest.
