THE DEFLEXION OF REINFORCED CONCRETE BEAMS UNDERTAKEN TO DETERMINE THE INFLUENCE OF LOADING ON DEFLECTIONS

An experimental investigation on reinforced beams undertaken to determine the influence of fluctuation of loading on deflections is described. The beams were subjected to a range of loading regimes usually with a fluctuating component. A linear logarithmic relationship was found between the increase in maximum deflection and the number of fluctuations or the length of time under load. Increases in deflection of beams under fluctuating loads were about the same as for beams subjected to sustained load equal in magnitude to the maximum of the fluctuation. The results are related to present design criteria and methods of analysis for deflections of reinforced concrete structures and the implications for design are discussed. /AUTHOR/
