Thanks for the answer Rapt,
I agree PTI alone is not the only source that should be used for design. It won't be the sole source, especially not the book I was mentioning.
I am viewing the ramp start and stop in my mind as essentially a giant P-big delta force. I think that type of moment...
I am designing a Post-Tensioned concrete parking structure (flat plate) with ramps between levels. I have obtained a few publications from PTI about the topic but my main question doesn't seem to be answered in them. That question is: do I induce crazy large moments in my slab from the...
I am wondering how other people interpret the concrete code above when it comes to classifying a strut as either prismatic or bottle shaped. Here is why the question arises:
Fig RA.1.3 shows a dark lined prismatic strut and a dashed lined bottle-shaped strut in an application that can clearly...

Thanks for the replies JoshPlum and IJR,
I think I was taking this to an academic extreme that can't take place because floor live load values rarely dip below 50, which in turn means that the live load reduction change with area won't ever make the "heavy" floor's load to the column reduce...
JoshPlum,
I agree some load is unreducible, but in this case 100 is reducible as only over 100 isn't reducible. I am more concerned with the problem posed by reducing based only on tributary area of columns without reference to what the various live loads might be.
thread167-142628
As pointed out in the referenced thread, the live load reduction for a column is based on its tributary area of all of the floors it supports.
It seems to me something is missing from this interpretation if for instance you have a column that services a 300 square foot area...
