This thesis is concerned with the inelastic behaviour of reinforced concrete members subjected to cyclic overload.
Theoretical methods for predicting the flexural behaviour of reinforced concrete members have been advanced and compared with experimental evidence at each stage in the development. Particular attention has been paid to the influence of conventional rectangular binding steel on the stress-strain properties of concrete and the effect on ductility in reinforced concrete beams and columns. The Bauschinger Effect in cyclically-stressed structural grade reinforcing steel was studied in some detail, both experimentally and theoretically, and a mathematical model for this behaviour was derived and is incorporated in the analyses.
Since cyclic loading predictions require the complete loading histories of the component materials to be known, and since both materials have complex responses to this type of load, all of the analyses have been programmed for computer use.
A further experimental programme using cyclicallyloaded beams was conducted in order to compare theoretical and experimental moment-curvature and load-deflection behavior. These beams were simply-supported and cyclically-loaded to simulate seismic response in beams at connections with columns. Close agreement between experiment and the proposed theories was found.
