Structural Engineering Software for Bridge Structures

In RFEM and RSTAB, traffic lanes can be defined directly on bridge members or surfaces. The software automatically generates the required load arrangements and combinations, including tandem systems and lane groups from national annexes.

This way, the governing load cases are covered without manual effort and always in compliance with EN 1991-2.

Yes. Bearings can be modeled with supports or spring elements, including nonlinear definitions for compression, tension, sliding, or friction, to capture realistic structural response.

Soil–structure interaction can be represented using elastic supports and springs for simplified models. This approach makes it possible to capture settlement behavior and ground stiffness without requiring complex soil data.

For more advanced projects, nonlinear soil models are available in RFEM, allowing you to simulate the behavior of different soil layers and their interaction with abutments, foundations, and piles. This enables engineers to assess differential settlements, rotational stiffness of supports, or even the effect of excavation sequences.

Temperature actions can be added as load cases – for example, uniform heating, temperature differences across the cross-section, or seasonal variations. These effects can also be combined with creep and shrinkage for long-term checks.

Yes. Fatigue verification is available for both steel and concrete members according to EN 1992-1-1 and EN 1993-1-9. The programs evaluate stress ranges and load cycles, and compare them with permissible values from the standard.

In practice, this means you can check whether reinforcement in concrete slabs meets fatigue requirements under repeated traffic loads, or whether welded connections in steel girders remain safe over the intended service life. The automatic verification not only prevents overdesign but also ensures long-term durability of the entire bridge structure.

Results can be documented in detailed printout reports with graphics, tables, and design checks. You can export to Excel or PDF in just a few clicks.

For BIM workflows, models and results can also be shared via IFC, SAF, or Revit, making collaboration with other disciplines straightforward.
