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 = 28 in., b2 = 15 in., d = 23 in., h1 = 6 in., h2 = 13 in., h3 = 9 in., and t = 6 in. There are four No. 8 longitudinal tension bars and No. 3 stirrups at 9 in. o.c.
