    Design tools

    WQ beams can be designed as simple single-span, cantilever and continuous beams.

    Design standard is Eurocode but country’s local standards can also be applied.

    Design curves

    The design curves are intended for pre-design only. They have been drawn in accordance with the standards EN-1993-1-1, EN1993-1-2, EN1993-1-5 and EN1993-1-12. Pre-elevation of the beams has been used to limit permanent load deflection. Ruukki makes the final design taking into account the requirements of each individual project.
