Old rebar question
Old rebar question
(OP)
I am trying to evaluate a floor system in a building that was constructed in 1919. The floor is a reinforced T-beam system made with clay tiles. I have the reinforcement schedule that indicates both round bar and another shape that I am not familiar with. It looks like a square with a "T" through it. I have attached a picture of the schedule.
Has anyone seen this designation before? Also, can someone direct me to some reference materials for typical rebar properties during the early 1900's?
Thanks

Any book published in the USA before 1923 is in the (USA) public domain (no exceptions)... and is likely available for viewing and download, in its entirety from Google Books. A good source when working on older structures.
