Multiframe 2023 (v23.07.00)

Multiframe is a suite of integrated structural analysis and design software for beam, frame and plate structures. It is ideally suited to unusual structural geometries such as those found in architectural and marine structures. It features a complete portfolio of analysis tools including linear, nonlinear, static and dynamic solvers linked to design code checks. Multiframe is widely used in Australia and Japan.

Significant changes in this release include:

  • Introduction of Bentley’s Fixed Lifecycle Policy;
  • Year-based version naming, e.g. Multiframe 2023;
  • Consolidation of all features into a single Multiframe tier (using the same product ID as the old Multiframe Advanced – 2144); and
  • Multiframe is now integrated under the MOSES brand.

The current release is Multiframe 2023 (23.07.00) from May 2023.

Multiframe and Multiframe Advanced are now consolidated into a single product with all the capabilities and features. This new product will be known as ‘Multiframe‘ and will be under the MOSES Bentley Offshore brand. The consolidated Multiframe has the old Multiframe Advanced product ID 2144 and is provided with a considerable reduction in cost.

About Load Panels
● Load Panels are a quick way to apply area loads
● Load panels convert an area/pressure load into distributed loads on the elements that support the edges of the panel
● A panel can be supported on 1,2,3 or 4 edges
● The edge loads on the supporting elements are calculated using the tributary area method
● Angles are bisected to determine adjacent areas

Load Panel Properties
● Once created the user can change the colour, label and supported edges of the panel

Panel Loads
● Pressure loads are applied to panels in the Load Window in global or local directions

Loads due to Panels
● The user can preview the edge element loads which are generated from the panel loads

Load Panel Results
● Analysis results are calculated exactly as if the user had applied the edge element loads themselves
