structural engineering
Analyse the load path. Then choose the design route.
Structural tools are separated into loading analysis, member design, and section properties. The design branch distinguishes code-neutral screens from tightly scoped Eurocode and Hong Kong calculations.
step 2 / structural branch
What are you trying to do?
Pick the engineering task first. This keeps load effects, capacity checks, and pure geometry from being mixed into one long list.
Loading analysis
Choose parameterized simply supported, cantilever, fixed, propped, overhang, or continuous beam cases, then continue to load take-off, stress, and stability screens.
Choose an analysis tool 02 / DESIGN9 liveStructural design
Use two code-neutral RC screens or choose scoped Eurocode and Hong Kong flexure, shear, section, and stability checks.
Choose material and code 03 / GEOMETRY5 liveSection properties
Calculate area, centroid, second moments, section moduli, and radii of gyration for common shapes.
Choose a section shapedesign basis / code route
Start code-specific design with the jurisdiction.
Each route begins with a narrowly declared calculation subset and keeps the remaining design modules visible as a roadmap.
Eurocode design
First-generation EN 1992 RC flexure/shear and EN 1993 section/flexural-buckling checks, with National Annex inputs visible.

Bounded concrete flexure/shear and steel section checks tied to published Buildings Department editions and amendments.
