Multiframe 4D - Dynamic analysis
Multiframe 4D contains everything in Multiframe 3D plus - Modal analysis
Time history analysis
User defined masses
Customisable force and acceleration databaseOne of the most demanding jobs a structural designer is faced with, is the dynamic analysis of an existing or proposed structure. To help solve these difficult problems, Multiframe 4D brings dynamic analysis to the Multiframe range. Using the same set of powerful and flexible modelling tools available in all the Multiframe programs, 4D is the fastest way to determine the dynamic response of the frames you are designing.
Multiframe 4D features a fast solver which uses sub-space iteration to quickly find the natural modes, frequencies and periods of your structures. For more complex problems, Multiframe 4D's time history response option allows you to simulate the structure's response to seismic or other dynamic loading over time. A built-in library of earthquake spectra can be used or your own dynamic data sets can be entered and stored for future use.
Either lumped or distributed masses may be used to automatically take account of the self weight of the structure. User control of the number of mode shapes or time steps and convergence criteria make it easy for you to calculate a quick estimate of dynamic response or a more rigorous and accurate solution. When analysis is complete, a click on a joint or member reveals a graph of its response over time. Alternatively, the whole structure can be animated to show the total structural response.

Fast and accurate structural analysis is the foundation of all computer aided structural design. Multiframe helps you get the results you require by providing powerful, yet easy to use, modelling, analysis and design capabilities.
Multiframe's 3D tools give you an exceptionally powerful and flexible means of creating, analyzing and examining results for your structures. A built in range of methods to automatically construct geometry, restraints, materials and loading conditions lets you concentrate on the problem at hand, not on the software you are working with. Although Multiframe offers ease of use and a completely graphical working environment, it also provides all the computational power you need for complex structural analysis.
All types of framed structures may be modeled and can include special structural features such as springs, prescribed displacement, member releases and pinned joints. Because Multiframe is designed to work the way you do, it offers automatic factoring of load cases, automatic inclusion of self weight and a range of commands to automate the generation of regular geometry such as continuous beams, curved beams, trusses and high rise frames.
Multiframe's built in library of common structural shapes let you analyze steel, concrete or timber frames. You can include sections made from any other material or automatically include sections designed using Section Maker.

Multiframe 2D - 2D structural analysis
Engineers with a limited budget will appreciate Multiframe2D as an ideal design tool for smaller scale problems which can be solved in two dimensions. Featuring all the modelling commands of the 3D module, 2D makes it easy to model, load and analyse two dimensional structures in minutes.
Simple or continuous beams can be quickly and simply sized or you can utilise Multiframe's capabilities for designing residential, commercial or industrial buildings. A simple portal frame or a more complex truss are all easily managed.
Regularly spaced structures are especially easy to handle as Multiframe 2D's snap-to-grid, automatic generation, and duplication, rotation and extrusion functions make light work of repetitive model construction.
The built-in library of common structural shapes let you analyse steel, concrete or timber frames. You can include sections made from any other material or automatically include sections designed using Section Maker.
Whether you are designing beams, trusses or frames, Multiframe's 2D analysis will give you the answer you need quickly, easily and accurately.

A custom structural shape is sometimes the best solution to your structural design problem. But designing and calculating properties of custom shapes can be time consuming and prone to error.
Section Maker helps you to design a shape simply and quickly and then integrate your shape directly into the Multiframe library of sections. Section Maker completely eliminates the need for any calculation of section properties by automatically computing the properties of steel, concrete, timber or sections made from any other material.
Whether the shape is complex, or even if it includes holes and multiple material types, Section Maker's range of drawing tools lets you easily construct the shape you require. If your data comes from another CAD system or drawing, you can easily import it directly into Section Maker. As you work with your shape, at every change the section properties are instantly re-calculated and displayed on-screen.
Once your shape is installed in the sections library and used in your structure, real time 3D renderings of your structure in Multiframe will display an accurate, detailed view of your custom section. Changes to the library are dynamically reloaded when you switch back to your Multiframe application.

The key to efficient structural design of steel is the optimisation of your structure in accordance with the applicable codes of practice. If you are using Multiframe for your analysis and you work with steel structures, then Steel Designer will automate the checking of structures to a range steel design codes.
Steel Designer is integrated with Multiframe so that it can directly access the results of your analysis and carry out design checks. But Steel Designer is not just a "black box", it gives you control over all aspects of the design process - which clauses you want to check; what effective lengths you wish to use; and how your output is to be presented. Steel Designer also provides you with a set of design aids which let you search through the structure for particular design criteria and graphically highlight areas of interest.
Detailed tables of stresses, deflections and forces for the whole structure, or just a single member, let you quickly and easily determine the governing loading conditions. Steel Designer provides you with a complete range of output combining text, equations, tables and diagrams. All your data can be copied and pasted to word processors, spreadsheets or drawing applications for further documentation. On-screen design of your report format is at your fingertips in Steel Designer. You can even remove parts of the report you don't require or add other tables or diagrams at any time. But most importantly, all of the interaction with the structure and the results of analysis, feature the same flexible and easy to use interface as Multiframe.

Multiframe Plate - Analysis of plate and stiffened plate structures
3D patch modelling approach
Totally graphical interface
Compatible with beam formulationAutomatic mesh alignment with patches and beams
Multiframe Plate allows you to include plate elements in your Multiframe structural analysis models. It features a 6 degree of freedom flat shell element which is compatible with the 3D beam element formulation used in Multiframe. It is also very stable and avoids the “locking” problems experienced by many plate elements.
Modelling using plates features the same easy to use graphical interface found in the rest of Multiframe. Plates are automatically organised into patches and where patches or members join each other, Multiframe Plate automatically remeshes to ensure nodal continuity across boundaries. The user can add holes to plate patches and choose either uniform or freeform triangular meshing.
The sketching, duplication and other geometry management tools which can be used on beams can also be used on plate patches. Initial geometry for patches can be imported from AutoCAD and other CAD systems via DXF. When applying properties such as materials, thicknesses and mesh density, Multiframe's familiar graphical interface is used.
When modelling a combination of beam and plate elements in the same model, you can use Multiframe’s Member Offset command to offset the neutral axis of attached beams to the plate field. This ensures an accurate calculation of the relative contribution to stiffness of the beams and plates in the model.
Pressure, line and distributed loads can be applied to plate patches. The location of these loads is parametric so that if patch geometry changes, loads update automatically.
Multiframe now features a new fast 64-bit solver optimised for Windows 7. This allows even large models to analyse quickly on current hardware.
The results of analysis can be displayed as forces, moments and stresses including Von Mises and Tresca stresses. Diagrammatic and contour displays help you to easily identify hot spots in the model.
