Suppose a suspension action is induced by 3/4 in. (1.91 cm) bolts on 5 ft (1.52 m)
Question:
Suppose a suspension action is induced by 3/4 in. (1.91 cm) bolts on 5 ft (1.52 m) centers (high strength) installed in the roof shown in the sketch. If the sag is then 40% of the unsupported sag of the suspended strata, what is the reduction in roof tension? Assume that the bolts are tensioned to 75% of the yield point.
