Per ACI 318 standards (Section 25.4.2.1 in 2014 edition) and the homework, when calculating the development length of deformed bars, what is the minimum value of ld?

Determine the bar-spacing factor, cb, for a simply supported rectangular beam with b = 18 in. and No. 4 stirrups. This beam has three No. 7 bars as longitudinal reinforcement. The clear cover is 2 in.

Learners are encouraged to jump into assignments such as discussions, activities, projects, and quizzes right away, before having read the chapters or watched videos/lectures.

Determine the casting-position modification factor, ψt, for a rectangular beam with b = 16 in. and d = 20 in., five galvanized No. 7 Grade 60 tension-reinforcement bars placed in the top of the beam, and No. 3 Grade 60 stirrups located every 12 in. along the span. Assume 4,000-psi normal-weight concrete and a clear cover of 1.5 in.
