case 2 : Ultimate -t M exceeds Mu.

The section is to be doubly reinforced.

However, it needs to check whether As' reaches yield

strength at ULS or not, using lqn &.6-10 of Chapter &.

IF (DDASH I X .LE. (1,0 - FY I 800.0)) GO TO 210

IF (DDASH I X .GT. (1,0 - FYI 800.0)) GO TO 220

I The compression steel As' reaches the design strength at
