| |
| | |
| *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
