First-order elastic direct-stiffness (FEM) Euler-Bernoulli analysis of a multi-span beam with variable EI, internal hinges, spring supports, prescribed settlements/rotations, thermal gradients and self-weight, plus natural-mode analysis. Sign convention: downward load positive, sagging moment positive, deflection reported in mm (up positive). Metric units. Verify the model independently; a licensed P.E. review remains required.
