SJI unit stresses in 1964
SJI unit stresses in 1964
(OP)
What was the unit steel stress, in psi, used in the SJI Standard Specifications for Open Web Steel Joists J-series dating back to the year 1964? I am checking the capacity of an existing roof truss to support additional weight due to replacement of Mechanical roof top units.
Thank you for your help.
