Deflection calculation of RC beams: finite element software versus design code methods

Abstract

The paper investigates accuracy of deflection predictionsmade by the finite element package ATENA and design code methods ACI and EC2. Deflection have been calculated for a large number of experimental reinforced concrete beams reported by tree 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.
