Hello,
We are just getting involved in a new job where we were provided existing drawings and the floor and roof framing are denoted "As Keene Super C Steel, 1200 J14 24" o.c. and As Keen Super C Steel, 1000J15 24" o.c." respectively. Has anyone heard of Keene Super C Joists? I am fairly sure unless I can find some manufacturers literature we are going to have t go measure some joists and then utilize AISI to determine some capacities. There are a few end games at consideration. One is to add a partial mechanical penthouse above the roof, the second is to re-roof the building. The county has already required an analysis showing that re-roofing the building will not cause any structural issues.
Building is essentially a large box, 488'-8" long by 45'-4" wide with interior and exterior load bearing walls on the short dimension. Every 40' along the length of the building there are full height CMU walls that extend above the roof and act as party/fire walls. Essentially creating individual units that are 45'-4"x40'-0". The building has one floor on grade, one elevated floor and the roof level.
