CALCULATION OF REINFORCED CONCRETE BEAM RELIABILITY ON THE CRACK LENGTH CRITERION

Cover Page

Abstract


The article describes the methods of calculation of reinforced concrete beams reliability at operation stage by the concrete crack length criterion. The offered methods differ in the fullness of statistical data about controlling parameters in mathematical design model. The numerical examples of reliability calculation are given. The article also illustrates the applica- tion of evidence theory for evaluation of mathematical expected value of reliability in the presence of statistical information in the form of a subset of intervals.
