Reading old drawing

[candice94]

Hi everyone,

I'm trying to understand what this detail means. I only have the plan view, no additionnal details. The drawing is from a buidling that was built in the 1950's. Has anyone seen this before?

Thank you in advance for your help.

Looks like the beams framing into the webs of the column are offset from the column center line by 3.75". Column looks to be 10H48# - which I take to be a 10" H section at 48plf. So I'm guessing your highlighted lines are the plates they call out and are meant to be shear tabs for the beams framing in.

Do you have access to the building to visually inspect the connection?

Nomenclature used and sizes of the 3 sections shown are not consistent with 1950's AISC listings.
