Multiframe Steel Design

Multiframe is no longer available as a standalone product.

The Bentley alternative offering is STAAD.Pro in which the Codes for Australia and New Zealand are as follows:

STAAD.Pro includes the main Australian steel, cold-formed steel, and concrete codes:

AS4100:2020 – yes (steel design)

AS4600: 2018 – yes (cold formed steel design)

AS 3600-2021 yes  (concrete design)

For the other materials:

AS 1664 (Aluminium) no  (only includes American Aluminum Code ASD 1994)

AS 1684 and AS1720 (Timber)  no  (includes Canadian, Eurocode 5 and US Timber codes)

AS 1170 loading – it doesn’t specifically implement Australian code loading/automatic load generation, but you can apply all the standard load types and factors as per the Australian code.

There’s general information on the implementation of the various Design Codes here: https://docs.bentley.com/LiveContent/web/STAAD.Pro%20Help-v2024/en/topics/Design_Codes/Australian%20Codes/c-stpst_Australian_Codes.html 

Or Multiframe is included with Maxsurf Naval Architecture software by Bentley.
