Eurocode

XFrame2d includes integrated Eurocode design checks for both steel and timber structures.

Steel Design - EN 1993-1-1

For steel beams, the following checks are performed:

• Cross-section resistance (N, V, M)
• Buckling resistance
• Lateral-torsional buckling resistance
• Combined bending and compression

Timber Design - EN 1995-1-1

For timber beams, the following checks are performed:

• Bending stress
• Shear stress
• Compression/tension stress
• Combined stress
• Deflection limits

Analysis Method

XFrame2d uses geometric non-linear analysis (second-order analysis) for Eurocode checks. This approach:

• Automatically includes P-delta effects
• Accounts for initial imperfections
• Allows buckling length equal to system length

See Buckling for more details on the calculation approach.

Unity Checks

Results are displayed as unity checks (UC):

• UC < 1.0: Beam satisfies requirements
• UC > 1.0: Beam does not satisfy requirements
