Precast Lin Tees (Single Tee not Double Tee precast planks
Precast Lin Tees (Single Tee not Double Tee precast planks
(OP)
I am looking at existing structural drawings for a building in Maryland and they indicate 8L36 Lin Tees. Not knowing what they were, I discovered that Lin Tees are single Tee precast concrete planks, similar to double tees today, only that they are single tees, developed by a guy with the last name "Lin", believe it or not, in 1962.
I need to evaluate the capacity of the single tee, however, the only information I have is that the stem is 8" wide, the T-flange is 8'-0" wide, and that they may have been fabricated by Baltimore Concrete Plank Company (or equal, as noted on drawings).
If anyone can help I would appreciate it. I am hoping there might be load tables out there somewhere for this.

I would think your best bet is to load test. Not sure if there is an ICRI spec or some other organizations documentation. Basically, you fill a bladder with water to a given elevation/weight and check the deflections.
As a caution, if this is a garage without field topping, you should verify the condition of the top flange reinforcement. It may be almost gone.
