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
- 4 to 9 node quad
- 4 node quad with incompatible modes
- 4 to 9 node RC panel (quad)
- 4 to 9 node Mindlin layer plate/shell
- 4 to 9 node Mindlin RC layer plate/shell
- Discrete Kirchoff triangle plate/shell element
