Design of hairpin rebars calculations
Weblayers (a hairpin detail—refer to Fig. 6). Depending on the specific reinforcement layout and spacing, hairpins may be more constructible than individual hooks. • It’s common practice to place sheets of welded wire reinforcement (WWR) between the two layers of reinforcing steel within the top mat. The WWR will allow laborers Webs = maximum C-C spacing of transverse reinforcement within the development length n = number of longitudinal bars being developed along the plane of splitting. Development Length in Tension With the proper bar to bar spacing and cover, the common development length equations are: #6 bars and smaller:or 12 in. minimum
