The following items have been considered in the evaluation of allowable compressive unit stress fc 'in S RC column since the SRC standard this time of 1958. (1) Decrease in concrete filling degree in internal steel skeleton. (2) Loss of concrete section damp by built-in steel skeleton. (3) Securing of the factor of safety for fragility destruction of pillar near center compression (4) Because strength is discounted to handle the concrete material as a plasticity material to apply the accumulation strength rule, the plasticity ability of the looking multiplication is expected. Concrete compressive strength is decreased in proportion to the amount of the steel skeleton and the experimental data concerning close yield strength is considered to agree to the calculation value. To improve a disadvantageous point of such a present standard type of SRC, it is to aim at the establishment of the assessment of reasonable concrete strength to which a concrete confined effect which the built-in steel skeleton configuration and shear reinforcement is taken.
