Re: Cambering Beams

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Method of reciprocal displacements.  Prescribe the deflection and solve for
the load using the applicable deflection equation.  This is typical for
elastic analysis.  For plastic analysis you will have to modify it depending
on the material properties of the steel and section properties of the beam.
