The IH S FP 1.2 application designs simple beam to column flange fin plate connections. The given joint is designed by using the EN 1993-1-8:2005 components methods.

This connection type is popular, as it can be one of the quickest connections to erect and overcomes the problem of shared bolts in two-sided connections.

Extended verification

Besides the preliminary set of pre-design checks for better geometric and coherence control, this connection conducts 14 different resistance checks, as well as ductility and rotation requirements.

Axial-shear interaction

The mathematics behind this connection allows for the interaction between axial force and shear where their effects are cumulative, like bolts in shear, weld stress or block tearing.

Comprehensive geometric options

Between notches, slotted holes and number of beams, the user has a vast array of options to choose from, in order to create the desired geometric layout.
