RE: End Plate (thick or thin?)
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
RE: End Plate (thick or thin?)
Not that thin plates are inherently bad. Just that they don't have ductility at the force / deflection levels necessary for high seismic.

I'm not sure that I've ever used it for new construction. But, I know other people have... my impression is that it has been used extensively in the metal building industry. So, if you're doing engineering work on an existing structure you might not have a choice....
RE: End Plate (thick or thin?)
thin plate used extensively in PEB structures, all steel companies try to decrease weight in every part in theses structures, however the weight of end plates will not make a problem in building weight but it is their philosophy to decrease the weight
other steel building use thick plates

RE: End Plate (thick or thin?)
Now, it may be just that no one has done this testing on the thin plate connections. Or, it may be that it may be the bolt behavior leads to less reliable ductility. I can't say for sure.
RE: End Plate (thick or thin?)
Sometimes engineers, this is mainly used by the elderly engineers as trick, select the beam size with free in bending rotations at ends, and put thick end plates instead of intended. However this trick does not work all the time. In case there is nothing to take the end bending on the other side, the column is forced to take the bending and rotate, sometimes this may cause fracture on the column. So take care on the details. Your question is very basic, and you need to know the answer without asking anywhere.
