Truss 101

A desktop application to solve statically determinate and indeterminate 2D truss structures using Matrix Displacement Method (aka Finite Element Method).

Why Truss 101?

• Develop Structures using Nodes and Members
• Unit conversion
• Supports
  • Pinned and Roller support
  • Stability check
• Multiple loads at the same point
• Individual property for members
  • Modulus of Elasticity (E)
  • Area (A)
• Nodal displacements
  • Graphs
  • Tabulated
  • Animation
• Member forces and support reactions
  • Force and stress
  • Graphs showing members relative strength
  • Tension, compression value in Tabulated form
• Influence line for a unit load
• Multiple projects
• Beautiful Report
  • Input-Output data
  • Member Stiffness Matrices
  • Global Stiffness Matrix
  • Force Matrix
  • Influence Line Diagram
