Comparative statistical deflection analysis of RC beams by FE software ATENA, design code methods and the flexural model

Abstract

The paper investigates accuracy of deflection predictions made by the finite element package ATENA, the design code methods ACI and EC2 and the Flexural constitutive model proposed by the second author. Deflections have been calculated for a large number of experimental reinforced concrete beams reported by three investigators. Statistical parameters have been established for each of the technique at different load levels, separately for the beams with small and moderate reinforcement ratio.
