We remove redundant restraints to make the structure determinate. We then calculate displacements caused by loads and the redundant forces, ensuring geometric compatibility (e.g., the deflection at a removed support must be zero). Deeper.22.08.25.mona.azar.and.alyx.star.make.it...
We treat joint displacements (rotations and translations) as the unknowns. We write equilibrium equations relating forces to these displacements.
