1980's Rebar Strength
1980's Rebar Strength
(OP)
Hi, checking an existing single-story concrete roof structure built between 1981-1983 in eastern Virginia, USA.
I know that both Grade 40 and Grade 60 rebar was available during that time period.
Does anyone know if Grade 60 was the 'standard' during that time? We don't know the rebar or concrete properties, so we need to make reasonable assumptions.
Will assume 3000 psi for the concrete which is probably conservative.
Thank you.

The Plan sheets refer to the "General Note Sheets" for design loads and strength properties, but we do not have those particular sheets.
