COLUMN

Design concrete, steel and timber columns with Simplex Column. Apply imperfections, eccentricities, and carry out 1st or 2nd order analysis and design.

Easy load definition: Apply loads and calculate their effects, define internal forces, or combine both approaches.
Flexible geometry: Model columns spanning multiple storeys. Apply local eccentricity offsets and define load positions.
Second-order analysis: Carry out a more advanced second-order analysis in accordance with the general method for concrete.

FRAME

Simplex Frame is a modern, easy-to-use 2D frame design software for steel, timber and concrete frame structures, in accordance with Eurocode.

Quick and easy modelling: Use modern tools to build your model on the canvas, or switch to the table view for a fast overview and easy model checking.
Load generators: Generate snow, wind and variable loads using built-in macros.
Powerful analysis options: Run first- and second-order analysis, eigenfrequency and stability analysis, and fire design for steel, timber and concrete. Include tension-only and compression-only elements. Consider shear deformations using the Timoshenko beam theory.

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.
