Beam Deflection Calculations

  • #1

Main Question or Discussion Point

Hello,

I am looking for some advice on calculating the beam deflection on a setup described below.

There is an "I Beam" sitting across the back of two lorry trailers with a uniformly distributed load in the middle of the beam.

I am slightly confused as to what type of support this would be if the beam is resting on the back of a flatbed to allow me to perform some hand calculations?

Any advice would be appreciated

These are called simple supports, and assuming there is no friction to support lateral loads, they are similar to roller supports in that the simple support resists vertical loads, such that their forces act in one direction upward on the beam.

Doesn't this also mean that the bending moments are zero at the ends of the beam?
