It is common that reinforced concrete beams in building frames are subjected to torsion in addition to flexural shear. In case the method of structural design becomes refined, although we have been neglecting the influence of torsion as a secondary effect, it is necessary to clarify the influence of torsion on the strength and deformation of a reinforced concrete member. This paper presents the results on the strengthes and deformations of the reinforced concrete beams subjected to combined flexural shear and torsion. The parameters used for the design of the test beams are as follows. (1) The ratio of shear span length to full depth (2) The ratio of longitudinal reinforcement (3) Concrete strength (4) The ratio of torsion to shear The interaction curves between torsional shear stresses and flexural shear stresses at the first diagonal cracks were presented as linear relations, and a formula to calculate the interaction curves is derived. The differences in the ultimate behavior of beams are examined. The rigidity reduction in torsion or in flexure and shear are discussed.
