shear in nonlinear formulation

[esi_opensees]

Hi all

Does opensees consider the influence of shear forces in nonlinear analysis formulation?

tnx.

Can you be more specific with your question?

As you know, the Euler beam theory is not suitable for deep beams. In these cases we may use Timoshenko beam theory. The formulation of Timoshenko beam theory for linear analysis is available in the literature. But I have not looked at the nonlinear formulation of Timoshenko beam theory myself and do not know of a book or paper that addresses it.
I want to know that can opensees consider the effect of the shear deformation in nonlinear analysis?
