Theoretical model of the determination of the deformation rates of RC beams

A theoretical model for the determination of the moment vs. curvature, and shear force vs. shear deformation relationships based on the stress–strain curves of materials given in ENV (1991), with material characteristics obtained from the tests of concrete and steel specimens is presented. A compari...

Description
Summary:A theoretical model for the determination of the moment vs. curvature, and shear force vs. shear deformation relationships based on the stress–strain curves of materials given in ENV (1991), with material characteristics obtained from the tests of concrete and steel specimens is presented. A comparison of the theoretical values with the results of tests for reinforced beams subjected to the concentrated force shows good agreement for both the curvature and shear deformations. The values of the deformation work due to bending moments as well as those due to shear forces were also determined.
