This project will have comments that reflect the default units: Newtons, millimeters, and tonnes. Other units are supported. See the documentation for details.

Features

• Input file format:
  • CSV
  • 3DD
• Static Load case:
  • Node loads
  • Uniformly-distributed element loads
  • Trapezoidally-distributed element loads
  • Concentrated interior point loads
  • Temperature loads
  • Prescribed displacements.
• Output
  • Node displacements (global)
  • Frame element end forces (local)
  • Reactions (global)
  • Peak frame element internal forces (local)
• Others
  • Geometric stiffness
  • Dynamic modal analysis
  • Extra node inertia
  • Extra frame element mass
  • Mode shape animation
  • Matrix condensation
  • Plotting results.

How to use

• Install frame3ddn from NuGet
• Create your own input or get it from a file

  • Input input = new Input(title, nodes, frameElements, reactionInputs, loadCases, false, false, 10, 1, 100);

  • StreamReader sr = new StreamReader(//Your File or file address); Input input = Input.Parse(sr);

    (You can find examples in frame3ddn/src/Frame3ddn.Test/TestData or frame3dd website)

• Solver solver = new Solver();
• Output output = solver.Solve(input);
• Directly use the result from output.LoadCaseOutputs in your code or get its text output from output.TextOutput.
