Following remarks are attained by beam column tests of Steel-Reinforced Concrete Members whose steel section is full-web type and the grade of steel used is SM 50 which is similar to ST 52 in quality. (1) Yield shearing strength of Steel-Reinforced Concrete Column, which tends to increse with axial load of the column, may be expressed by Eq. (10) as seen in Fig.21 (a). (2) Yield bending strength of Steel-Reinforced Concrete Column can be expressed by Eq. (9) and also maximum bending strength of Steel-Reinforced Concrete Column can be obtained by superposed strength method as seen in Fig.21(b) and (c). (3) The astringed strength by cyclic loading whose deformation amplitude is about ±0.01 radian can be expressed by Eq. (11). (4) The deformation amplitude when the hysteretic loop comes to be unstable by cyclic loading decreases with the increase of the axial load of the column (see, Fig.23).
