AN ANALYSIS OF THE DESIGN OF BEAM TESTING APPARATUS

A critical evaluation of the mechanical design of beam testing apparatus used to determine the flexural strength of concrete by ASTM methods C 78-64(1972) and C 293-68 is presented. Two approaches were used in the evaluation: (1) an experimental deformation of the concrete beam analysis and (2) a stress-deformation analysis of the same by the finite element method. An alternative design of beam testing fixtures is presented by which the tests can be performed more efficiently and accurately.
