# Small planar frame
# Scope: Single-story ideal shear frame with two fixed-guided columns; rigid crossbeam.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

height = 1 m
inertia = 1000000 mm^4
modulus = 200 GPa
force = 1000 N

stiffness := 24*modulus*inertia/height^3 [N/m]
sway := force/stiffness [mm]

check sway budget: sway <= 2 mm

scenario alternative: height = 0.8 m
