| Abstract | Ten reinforced concrete specimens of the same design were subjected to combined bending and torsion varying from pure bending to pure torsion. From the data, an interaction curve for torsional and bending moment was developed. It appears that when induced bending moments are small in magnitude, an increased torsional capacity of the beams results; when induced bending moments are large enough to cause flexural cracking in the beam, the torsional capacity will be reduced. From experiments, two distinct types of failure for the reinforced concrete beams were observed; a primary bending failure associated with the development of vertical flexural cracks, yielding of steel and crushing of the compression face of concrete, and a primary torsional failure associated with the development of 45 degree helical cracks occurring around the entire perimeter of the beam. To verify the validity of the interaction curve, two reinforced concrete frames were subjected to combined bending and torsion. The test results show that the actual ultimate loads are close to the pre¬ dicted ultimate load as determined from the interaction curve. |
