Sign convention for internal forces
Structural elements must resist forces within itself – the so-called internal forces – which are produced by external forces like dead load, snow load, wind load, etc. If the structural elements don’t resist those internal forces, the elements break/fail. In general, there is 3 different internal forces 1.
