Plastic hinging in reinforced concrete
Complete load-deflection history of 18 beams tested during 1952-54 and 18 beams tested during 1959-61 at University of Illinois allowed study of factors which contribute to ductility; primary variables studied included depth, compression steel ratio, concrete strength, amount of transverse reinforcement, and ratio of compression steel area to tension steel area; modes of failure reflected importance of confinement of concrete in compression zone in insuring capacity for large plastic rotation at joint; first crushing of concrete was found to be associated with deflection much smaller than that corresponding to ultimate load; for beams with compression steel reverse ductility beyond first crushing was large, deflection at ultimate load in some cases being more than 10 times first crushing deflection.
