Abstract:
The integral relationship between stress and dilatation of concrete has been presented in an algebraic form. This makes the solution of problems for stress changes of concrete structures easy. Expressions for determinations of stress changes in singly reinforced concrete sections on the basis of integral relationship applying the aging theory are given. For determination of stress losses and dilatations, convenient diagrams are presented for single and multilayer reinforced concrete sections.
