Deflection of over-reinforced concrete beams: comparison of analytical, numerical and experimental results

Prediction and forecasting of deflection is a complex assignment because of the factors which are varying along the axis and with the time. Thus, the approximate procedures are used, in which the obtained results are mutually different and different in a comparison with values measured on real structure. In this paper an analytical calculation of deflection of five over-reinforced concrete beams according to Eurocode 2 is presented. The beams had different dimensions in order to investigate the impact of beam size on load-bearing capacity and deflection of over- reinforced concrete beams. Comparison of deflection obtained analytically, according to Eurocode 2, and the results obtained experimentally and numerically by other authors, is also presented. The major objective of this research is to determine the differences between the analytically obtained results, and experimentally and numerically obtained results.
