Joints

In version 3.01 and later, XFrame2d includes a comprehensive steel joint module. Moment-fixed steel joints can be entered and their rigidity is automatically taken into account in the analysis.

Joint Types

The module supports various joint types according to Eurocode EN 1993-1-8:

Beam-to-column joints
Beam-to-beam joints
Column bases

Joint Properties

For each joint, you can specify:

Connection type
Bolt configuration
Plate dimensions
Weld sizes

Rigidity

The joint rigidity is calculated according to the Eurocode component method. The calculated stiffness is then used in the structural analysis, providing more accurate results than assuming fully rigid or fully pinned connections.

Calculation

See Joints Calculation for details on how joint rigidity is determined.
