Nonlinear material influence on reinforced concrete beams’ immediate deflections

Alexander Gómez Cassab / Juan Manuel Lizarazo Marriaga

This paper presents an analytical and experimental research programme’s results regarding material nonlinearity’s influence on reinforced concrete beams’ immediate deflections. Six full-size laboratory beams were tested under different type of loads in the experimental programme. The ANSYS finite element software nonlinear material model was used for simulating the beams’ analytical behaviour. Comparing ANSYS nonlinear material model results, ACI 318 equations and the results of the tests made revealed that a beam’s structural behaviour is strongly influenced by material nonlinearity.
