Non linear analysis of a simply supported beam under UDL 3

[Samuee]

If we consider a simply supported beam under uniform distributed load,

when it deform, the vertical load will transform to vertical and horizontal support reaction (As the member is already tilted at the support side).

As such, support should experience axial pulling force by the beam.

I wanna know the above illustration is correct or not.

true there'd be some point where the rotation of the end off-sets the strain of the span ... but you can't restrain the beam there. if you did the end section would rotate about this point and the zero strain point would move again. The zero strain point must be offset from the pinned restraint. Sort of figuring out how many angels can dance on a needle ...

rb1957,

Hardly seems worth arguing about, since it has essentially no significance in a real structure, so I will let it go for the moment.

[rb1957]

as per Monty Python ... "this isn't an argument, it's a contradiction". and yes a very theoretical point we're discussing.

Gotta give you a star for the excellent Monty Python quote....

this isn't an argument

Yes, it is!

it's a contradiction
