Why Choose Simplex Frame?

Load Generators

Generate snow, wind and variable loads automatically based on Eurocode and national parameters.

Transparent Results

Transparent results with step-by-step formulas and Eurocode references for clear, professional reports.

Fire Design

Design steel, timber and concrete sections for fire exposure, with defined exposure time and protective materials.

Auto Design

Group members and carry out section design automatically by optimising sections based on your selected library.

Explore Simplex Frame’s Capabilities

Intuitive user interface: Draw directly on the canvas or input data in tables – the choice is yours. A streamlined workflow where analysis and design are carried out in one step, with object-based properties throughout.
Multi-material design: Analyse and design timber, steel and concrete frames, including fire design, in accordance with second-generation Eurocode and national annexes when available.
Varied analysis options: Carry out stability, eigenfrequency and second-order analysis for a complete workflow, regardless of material.

Load generators: Generate wind and snow loads automatically using smart load generators. Automatically generate load combinations and define variable loads for multi-span and multi-storey structures quickly and easily.
Non-linear elements: Consider compression-only and tension-only elements in your structural design.
Shear deformation: Use Timoshenko beam theory to account for shear deformation in deep beams or beams with low shear stiffness.

Auto design: Group your sections and define utilisation limits for automated section design, providing a practical and efficient way to optimise your structure.
Fire design: Calculate steel temperatures with regard to fire protection, delay timber charring through protective layers, and consider temperature gradients across concrete cross-sections with temperature-dependent material reductions for detailed fire design within the software.
Transparent results and reports: View detailed step-by-step code checks within the software, with references to Eurocode, or generate detailed reports from predefined templates, making verification simpler and reports clearer for all stakeholders.

Transition Roadmap

From Legacy to Simplex

Now

Q3 2027

Q2 2028

Onwards

Stage 01 Stage 02 Stage 03

Stage 1: First-Generation Eurocode

Now → Q3 2027

During this stage, we are introducing the SIMPLEX apps alongside our legacy software. Existing users of WIN-Statik, DIMENSION, JIGI and Matrix Geo will receive access to the corresponding SIMPLEX apps, in addition to their current licences, as soon as they become available. This gives you double licences and access to both platforms at the same time, helping you move to SIMPLEX gradually and with minimal disruption.

Stage 2: Transition Period

Q3 2027 → Q2 2028

During the Eurocode transition period, SIMPLEX will become the platform to be used for Eurocode generation 2. The basic Eurocode is already in place, and we are ready to implement the national annexes as they become available. You will still retain access to your existing WIN-Statik, DIMENSION, JIGI and Matrix Geo licences, but those legacy products will remain on Eurocode generation 1 and will not be updated to generation 2.

Stage 3: Second-Generation Eurocode

After Q2 2028

After the transition period, SIMPLEX will continue to grow with new products and innovations. The legacy products will still be available for old projects and for access to old calculation files. SIMPLEX is the future-proof platform for second-generation Eurocode and a future with AI-aided engineering.
