Simplex Beam Design Software - User Interface

  • Intuitive user interface: Start designing in seconds with user-friendly cloud software, with no set-up required. Replace time-consuming Excel work with a more streamlined workflow.

  • Foundation design in accordance with Eurocode: Design and verify strip and pad foundations for point and line loads, including geotechnical calculations and full soil–structure interaction, in accordance with EC0, EC1, EC2 and EC7, including the national annexes for Sweden, Denmark, Finland, Norway and Great Britain. The software is also being prepared for the upcoming second-generation Eurocodes to remain future-proof.

  • Optimised designs: Use the auto-design feature to find optimised foundation dimensions and reinforcement layouts that reduce material use without compromising safety. First optimise the foundation size, then run the reinforcement design as a second step. Stay compliant with Eurocodes while also reducing CO₂ emissions and carbon footprint.

  • Combined Capacity Checks: Check both soil and concrete capacity — all within one program

  • Punching calculation: Carry out relevant punching checks in accordance with EC2, with clear illustrations of critical sections and design conditions as part of the overall foundation design.

  • Automated reporting: Generate detailed reports from predefined templates, including analysis results and step-by-step design checks, making verification simpler and presentation clearer for all stakeholders.

  • Circular failure line: In addition to the standard failure line, Simplex Foundation also considers a circular failure line in accordance with recent DSSSE guidance and methods. This optional check is available for all annexes.
