    • print element data
    • print node data
    • print all domain-object data

Under-Development Requirements

Element

  • 2D/3D Wall Elements
  • 3d nonlinear frame element with full interaction
    • axial
    • flexure
    • torsion
    • shear

Section

Output

Other

To-Be-Developed Requirements

Element

  • Buckling-Brace Elements
  • Flexible Diaphragm
  • 2D & 3D Isolators
  • 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

Section

  • 2d normal and shear stress interaction

Material

  • 3d J2 plasticity with kinematic and isotropic hardening
  • 3d plastic-damage concrete constitutive model Lee-Fenves

Output

  • Specify recorder to save only every Nth timestep (specifying dT only works for time-history analyses)
  • EnvelopeDrift Node recorder

Other

  • improved domain-data output

Continual-Development Requirements

Documentation

  • OpenSeesWiki
  • Validation with experimental data
  • Materials
    • Graphical demonstration of input-arguments
  • Examples manual
    • Practical Examples
  • Theoretical Background
