Moment Connections - Connection Types

The design of rigid moment resisting connections is carried out in accordance with the joint model and design methodology as given in the SCI Green Book publications. The range of connection types covered by the MasterKey: Moment Connections module are:

The connection types feature the following features which can be added as necessary by the user.

Eaves Connections

Left, right and double connection types
Extended end-plates
Haunches checked for stability of the cut
Beam and column web stiffeners can be added
Gusset and/or full width stiffeners can be included
Morris, diagonal, K and double plate stiffeners
Design of welds includes haunch welds
Bolts can be specified as 4 per row, with the extended end plate being able to be defined separately

Apex Connections

Left and right connections
Extended end plates
Haunches checked for suitability of cut
Beam web stiffeners can be added
Design of haunch welds
Backing plates
4 bolts per row

Base Plate Connections

Includes open I- and H-sections and hollow sections
Stiffeners can be specified and added
Circular base plates for use with CHS column section
