## Abstract The prediction of nonโlinear structural behaviour by the finite element method wherein buckling does not occur has received considerable attention and, with it, reasonable success has been achieved. However, the postโbuckling problem has been less actively pursued probably because of th

## Abstract To perform nonโlinear structural analysis including large displacements and rotations requires evaluation of the nonโlinear equilibrium equations. A quadratically converging, fixedโpoint iteration scheme, referred to as the workโincrementโcontrol solution method, is presented to iterati
In the paper a modified non-linear member element is derived which can lead to satisfactory computed results even for large loading and displacement increments from pre-instability to post-instability of structures. The high accuracy of this element is proved by numerical examples.
