Following remarks are attained by beam-column tests of Steel-Reinforced Concrete Members whose steel section is full-web type (H section). 1) The flexural cracking strength and shear cracking strength of Steel-Reinforced Concrete columns can be expressed by Eq. (1) and Eq. (2) respectively. 2) The flexural yield and maximum strength of Steel-Reinforced Concrete columns can be estimated by the theory based on the Navier's assumption. The superposed flexural strength can estimate the flexural yield strength approximately, but underestimates the flexural maximum strength of Steel-Reinforced Concrete columns. 3) The modes of fracture of Steel-Reinforced Concrete columns can be classified into two modes with the axialload proportion whose bounds is N/bDF_c=0.4. They correspond with the modes of flexural yielding of Steel-Reinforced Concrete columns. 4) The deformation capacity of Steel-Reinforced Concrete columns depends mainly on the axial-load proportion of columns and can be expressed by the empirical equation (6).
