Pan Joist - "Single Tapered End"
Pan Joist - "Single Tapered End"
(OP)
I've worked with concrete pan joist systems for years and am familiar with tapered end forms where the end portion of the joist (typically the end 3 feet) is tapered wider to get more shear capacity...usually about 5 to 6 in. more width.
I've got a project built in 1965 where the design plans use the term "Single Tapered Ends" and call for them on the plans for some joists I'm checking.
The problem is, I'm not sure what the "single" means as I've never seen where only one side of the pan form is tapered and the other isn't. On top of that, my field inspection and photos show no such taper occurring in actuality.
The shear capacity doesn't seem to be adequate and the tapers are missing...unless I'm missing something. I wonder if they added stirrups instead?
Anyone ever hear of Single Tapered Ends?

In any event, it seems like they didn't do what was requested on the drawings.

I wondered if they didn't have STE's and substituted some small stirrups...but we don't have the equipment or time right now to investigate further at this stage.
