Data Report Number 48 "Evaluation of Reinforcing Bars in Old Reinforced
I am working on adding some roof top units to an
existing building. Date of original construction is unknown. The
roof framing consists of a 4.5" concrete slab on 8"x14" monolithic beams
with square columns. In a few areas, the slab was demo'd previously
for added vents, etc. The rebar is 1/2" square and twisted, 7"oc each
way. Anyone ever seen such?
