Lumped Plasticity hinge stiffness
Lumped Plasticity hinge stiffness
(OP)
Hi all
For lumped plasticity model of a column or a beam the plastic hinge stiffness is 6EI/L (assuming double curvature).
My question is how to derive this equation? and what is the stiffness for a singe curvature (cantilever)?
Thanks
