Enter the spans and loading, and Volex Anvil solves the continuous beam — support moments, span moments, shear forces and reactions — by the stiffness method, then designs the critical sections in steel, RC or timber to the relevant Eurocode.
The analysis is checked against classical closed-form results (Timoshenko, 'Theory of Structures') for equal-span cases, so the moment distribution you get matches the textbook — with the full bending-moment and shear diagrams shown.
