This paper continued from the last number and the contents of this report are as follows. A series of test pieces made out of reinforced concrete cantilever columns(the area of section; 20cmX20cm,the length; 50cm), which are reinforced with four steel deformed bars in the four corners(the ratio of reinforcement area; 0.71% -410series and 1.27%-413series), so called concentrated reinforcement types, and with eight steel deformed bars in the four coners and in the four midside(1.43% -81Oseries and 2.54%-813series), so called dispersed reinforcement types, and the all of them hooped with steel round bars at intervals of 50mm(0.31%), were tested and examined. We adapted them to a few hysteresis types of lateral force with the principal direction and the diagonal direction under the constant axial force. The number of test pieces are as follows. 6pieces-410series, 26pieces-413series, 14pieces-810series and 6pieces-81 Sseries. And empirical formulae, which evaluate ultimate moment of bi-bending under the axial force, are proposed and examined.
