Chapter 6. Compression Reinforcement - Flexural Members
Total resisting moment can be considered as sum of: 1. Moment from corresponding areas of tension and compression steel 2. The moment of some portion of the tension steel acting with concrete. M n =(A s −A s′) f y (d − β 1 c 2) +A s′f y (d −d′) (6.2) and from equilibrium: 0.85f c′ab =(A s −A s′)f y (6.3) Solve for “a”: a ...
