RC beam flexure and shear
Use a code-neutral flexural mechanics screen or bounded Eurocode/Hong Kong resistance checks.
structural / design
Choose the material. Then choose the design code.
Material behaviour and the governing jurisdiction are separate decisions. CivilKits keeps code-neutral screens distinct from released code subsets and from the remaining roadmap.
step 3 / material
Choose the structural material.
Start with reinforced concrete or structural steel, then select the code basis and read the declared calculation scope.
Steel section and member resistance
Calculate tightly scoped section resistances or two-axis Eurocode flexural buckling from verified section properties.
step 4 / design basis
Choose the code family.
Each route shows its released section checks, source editions, adjustable national parameters, excluded checks, and next modules.

Every live code tool is a declared subset, not a complete design. Interaction, serviceability, durability, fire, omitted stability modes, detailing, combinations, connections, and professional review remain separate unless explicitly stated.
