Tools / Truss analyser

Truss analyser

Member forces (tension or compression) and support reactions in 2D pin-jointed trusses.

For learning and quick checks only. Not for design or construction.

Build the truss

Add nodes by coordinate, connect them with members, then add supports and joint loads. Results update as you go. Statically determinate trusses only (m + r = 2n).
