In the previous paper, the test results on the strengthes and deformations of the small reinforcd concrete square beams without stirrups subjected to combined flexural shear and torsion were reported. The identical beams with stirrups tested herein are related to the previous work in property. The parameters used for the the design of the test beams are as follows. (1) The ratio of shear span length to full depth (2) The amount of longitudinal reinforcement (3) The amount of web reinforcement (4) Concrete strength (5) The ratio of torsion of shear An empirical equation to calculated the interaction curvessat the first diagonal cracks derived in the previous paper has been applied to the test data, which covers beams with stirrups. It can be seen that the agreenment between predicted and observed test values is very good. The interaction curves between torsional shear stresses and flexural shear stresses at the ultimate strength were presented as ellipse relation, and a formula to calculate the interaction curves is derived.
