Unusual Joist Designation
Unusual Joist Designation
(OP)
In the current project we are adding RTU's to the roof of an existing space for a new tenant. We were fortunate enough to get the existing structural drawings but there joist designations were not like anything we had seen in the past.
The engineer called out a specific designation AND provided a joist loading diagram. For example one of the designations was 26KSC2 SP4. The SP4 references us to a joist loading diagram. Have any of you seen anything like this before?

Perhaps this is meant along with specific loading?

I've been getting varying answers. I just called Vulcraft to possibly getting some input on this.
Also, this was for the city of Chicago which has a VERY old building code. Not sure if that helps.
