Shear forces, bending moments, and torsion [8].
Channels like " Understanding Structures with Fawad Najam " offer visual deep dives into these principles [18]. Fundamental Structural Analysis
It is tempting to rely entirely on software like SAP2000 or Staad Pro [17]. however, professional engineers use fundamental formulas (like the simply supported beam point load equations ) to perform "sanity checks" on software outputs [2, 14]. If the computer says a beam won't bend but your hand calculation says it will, you've just prevented a potential site failure [10].
