Basis & combinations
Design situations, limit states, partial factors, and transparent ULS/SLS combinations.
design code / eurocode
Eurocode design route.
Move from EN 1992 beam flexure and shear to EN 1993 cross-section and two-axis flexural-buckling checks, while keeping the remaining actions, serviceability, stability, and detailing roadmap visible.
live subsets + roadmap
From actions to member verification.
The route follows the Eurocode family and keeps Nationally Determined Parameters visible rather than hiding them in defaults.
Actions on structures
Self-weight, imposed, snow, wind, thermal, and other actions as applicable to the selected project.
Rectangular RC beam flexure
First-generation EN 1992-1-1 ULS sectional resistance with visible αcc, γc, γs, and a tension-yield gate.
Open EC2 calculator EN 1992Live subsetRC beam shear and vertical links
Concrete resistance, minimum or designed links, provided VRd,s, and the VRd,max compression-strut limit.
Open EC2 shear calculator EN 1993Live subsetSteel cross-section resistance
First-generation EN 1993-1-1 gross axial yield, major-axis bending, and plastic shear for declared Classes 1–3.
Open EC3 calculator EN 1993Live subsetColumn flexural buckling
Two-axis slenderness, explicit effective lengths and imperfection curves, reduction factors, and Nb,Rd.
Open EC3 buckling calculatorNDP required
Eurocode calculations may depend on Nationally Determined Parameters and a National Annex. A future calculator must require or clearly display the chosen country or parameter set; “Eurocode” alone is not a complete project basis.
calculation basis
Know what the first release does—and does not do.
The calculators implement only their declared section or flexural-buckling equations. They do not generate actions, choose a National Annex, classify a steel section, or complete every member-stability and detailing check.
