Niniejszy artykuł jest związany z trwającym projektem, w ramach którego opracowywany i wdrażany jest cyfrowy bliźniak konstrukcyjny mostu Kalix w Szwecji.
Design loads specified in the AASHTO Bridge Design Specification are available in the RF-MOVE Surfaces moving load library. Design Truck (HS-20), Tandem, Type 3, and Overload are available options.
Poniższa konstrukcja jest opisana jako przykład IV.10 w [1] "Komentarz do Eurokodu 3". Für die Stütze mit linear veränderlichem Querschnitt ist der Nachweis ausreichender Tragsicherheit (Querschnitts- und Stabilitätsnachweis) zu erbringen. Due to the unequal structural component, it is necessary to perform the stability analysis (from the main support direction) using the method according to Section 6.3.4, or alternatively, according to the second-order analysis.
W module dodatkowym RF-LAMINATE można wymiarować elementy konstrukcyjne wykonane z drewna klejonego krzyżowo. Since the design is a pure elastic stress analysis, it is necessary to additionally consider the stability issues (flexural buckling and lateral-torsional buckling).
In the AISC 360 – 14th Ed. C2.2, the direct analysis method requires initial imperfections to be taken into consideration. The important imperfection of recognition is column out-of-plumbness. According to C2.2a, the direct modeling of imperfections is one method to account for the effect of initial imperfections. However, in many situations, the expected displacements may not be known or easily predicted.
Requirements for the design of structural stability are given in the AISC 360 – 14th Ed. Chapter C. In particular, the direct analysis method provisions, previously located in Appendix 7 of the AISC 360 – 13th Ed., are described in detail. This method is considered an alternative to the effective length method, which in turn eliminates the need for effective length (K) factors other than 1.0.
W styczniu 2015 r., DIN Committee NA 005‑08‑23 Steel Bridges zastosował modyfikację równania 10.5 w normie DIN EN 1993‑1‑5. Es handelt sich hierbei um die Interaktion von Längs- und Querdruck im Beulnachweis. Diese Interaktionsgleichung sieht nun den Hilfsfaktor V vor, welcher sich aus den Abminderungsfaktoren der Längs- und Querspannungen berechnet.
