LONG-TIME BEHAVIOR OF REINFORCED CONCRETE BEAMS SUBJECTED TO PURE TORSION

Results from a theoretical and experimental investigation on cracked reinforced concrete members subjected to a long-time torsional load are presented. The theoretical relationships are obtained from a truss model. An expression for the torsional stiffness in the elastic stage is modified to take into account the effect of creep of the concrete. The experimental work comprised tests on eight rectangular beams with different amounts of reinforcement and subjected to different load levels. The long-time tests were run for a year then ultimate tests were performed.
