Description: Computes rod and support reaction forces for a statically determined truss system.

Input arguments:

  • nodes: n x 2 matrix containing x- and y coordinates, n denoting the total number of nodes
  • rods: r x 2 matrix defining rods (1st node to 2nd node), with r denoting the number of rods
  • forces: f x 3 matrix defining node forces (node number, force in x direction, force in y direction. f denotes the total number of forces.
  • supports: s x 3 matrix defining the supports (node number, constraint in x-axis, constraint in y-axis). s denotes the total number of supports. For the constraints, and entry of 1 denotes a constraint in that direction, 0 denotes no constraint in that direction.
Output:
  • s: resulting rod forces (negative value = pressure force, positive value = tension force).
  • a: resuting support reactions.

2 demonstration geometries are included. Start with 'main'.

Keywords: statically determined system, truss, mechanics, rod forces
