Bar splices were kept under constant load for more than 2 years during which time one bar of one test moved past the other 0.04 in. under a bond stress of 153 psi without losing the load. This was six times as treat as the average of five other tests. Stresses in the steel of similar specimens not under load showed that practically all of the stress due to shrinkage disappeared after 25 days. Before cracking occurred the stresses were only 40 percent of those calculated from data of unreinforced shrin kaqe.
