To-Be-Developed Requirements

Element

Buckling-Brace Elements

Flexible Diaphragm

2d Timoshenko beam element

3d frame element with bond-slip of reinforcing steel

3d frame element with slip between components, e.g. composite beam, composite column

3d concentrated plasticity element with return map algorithm

2d SIZE (spreading inelastic zone) beam element

Nonlinear geometry developments

Extension of corotational theory to membranes and shells
Reformulation of 3d frame nonlinear geometry such that any element can take advantage of nonlinear transformation (currently not the case); quaternions vs. rotation nodal variables require either a change in global solution strategy or the mapping back and forth between quaternions and node rotations.

The following elements include linear or corotational geometry for membranes and shells under large displacements

3 to 6 node triangle
