Thanks Carlos - that added functionality will be useful.

Hi Nic,

The approach we use is called the “Simplified method” which is in the page 8 of the Design Guide 13 – Splice connections of the Australian Steel Institute.

By this approach, the moment is taken by the beam flanges, the shear is taken by the web, and the axial in the beam is prorated to the areas of flanges and web.

We are planning to do an enhancement to add the options for elastic and plastic analysis of this set of forces for the design of the connections in the web and flanges this year.

Hi Seth - this is quite limiting for the design splices in deep beams where the web contributes quite significantly to the moment capacity.
Where in AS4100 does it say that the moment in a bolted splice need to be taken by the flanges only?

In the flange plate moment splice for beams in Ram Connection the moment is entirely resisted by the flange plates and the web plate (second connection) is just for shear. Same for AS 4100 or AISC codes.
