A continuous beam’s flexural reinforcement must extend at least _____ from the point where it is no longer needed to resist tension. Assume f’c = 4,000 psi, fyt = 40,000 psi, b1 = 32 in., b2 = 16 in., d1 = 4 in., d2 = 15 in., and that there are three No. 6 longitudinal tension bars and No. 3 stirrups at 10 in. o.c. The stirrup hooks are 90°.
