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:

Beam to Column Flange (eaves)

Beam to Beam End-plate (apex)

Beam Splice

Column Splice

Hollow Section Splice (end plate)

Column to Beam (beam above or below the column)

Base plate

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

Asymmetrical bolt arrangements for base plates with moment, axial and shear

Axial up lift for symmetrical base plates

Columns can be offset laterally

Bolts can be specified in up to four rows, with multiple bolts per row.

Shear keys can be added, formed from plates, angles or stubs cut from standard open or closed sections.

Beam Splice Connections

Connections include for the design of axial, shear and moments

Internal as well as external plates can be added
