Abstract A fiber–hinge beam–column element considering geometric and material nonlinearities is proposed for modeling steel–concrete composite structures. The second-order effects are taken into account in deriving the formulation of the element by the use of the stability functions. To simulate the inelastic behavior based on the concentrated plasticity approximation, the proposed ...

In short explained: Linear and nonlinear structural analysis

May 22, 2017  Nonlinear analysis. A nonlinear analysis is an analysis where a nonlinear relation holds between applied forces and displacements. Nonlinear effects can originate from geometrical nonlinearity’s (i.e. large deformations), material nonlinearity’s (i.e. elasto-plastic material), and contact.
