[blocks in formation]

Slab top bars shall be bent down into the marginal beams at "a" because of difference in slab bar and beam stirrup spacing not producing proper lap.

180 or 135° Hook

Discontinue the use of these types. The out-turned hook on large size stirrups
may be too large for thin slabs. The above shapes provide the neces-
sary anchorage, which hooks would provide, as well as reinforc-
ing the connection of the slab to the beam.
