Fixed or simply supported boundary condition.
Fixed or simply supported boundary condition.
(OP)
A 5" width, 1" thickness, 12" clear span plate, exerted a load P. I guess most people will consider case (a) as simply supported boundary condition, and case (b) as fixed boundary condition.
My question: is there any statement in any code which can justify above assumption?
Should there any limitations for the weld size so that below certain weld size, the steel plate beam can no longer considered as fixed end. or this limitation has to be based on load balance calculation?

Certainly if you weld 1/2" of the 5" dimension it will act more like a pinned support, but why are you welding it?

Remember that you are going to get some prying action in your setup.
RE: Fixed or simply supported boundary condition.
Since Maximum Moment for simple supports = P x L / 4
and
for fixed supports = P x L / 8
for what you have shown in the sketch I would estimate the following:
Case "a" (bolted connection) M Max = P x L / 6
Case "b" (welded connection) M Max = P x L / 7
Just an opinion based on the assumption that the OVERALL length of the plates in cases "a" and "b" is identical.

Thank you both very much.
