Streamlining FEM-Design for bridge dimensioning : Traffic load on bridges (English)
Abstract [sv]

FEM-Design används i allmänhet för dimensionering av huskonstruktioner. Detta arbete syftar på att göra programmet mer anpassningsbart för brodimensionering. Examensarbetet går ut på att integrera militära fordon i FEM-Design modeller. I det här examensarbete har hjulfordon, bandfordon och konvojer modellerats. Ett tidigare examensarbete om modellering av typfordon och lastmodellering kontrollerades i detta arbete. Det kontrollerades för att säkerställa att modelleringen har skett på ett korrekt sätt. Lasterna analyserades genom att sätta in de tidigare modellerade lasterna på en platta respektive en balk, där momentdiagrammet skulle ge samma resultat som om den hade gjorts för hand. De militära fordonenslasterna beräknades efter trafikverkets krav och resultatet definierades i FEM- Design, så att resultatet ska kunna användas vid dimensionering. Arbetet tillsammans med Strusoft AB resulterade i att 128 nya laster modellerades i FEM-Design. Dessutom kontrollerades 30 redan modellerade typfordonslaster av lastmodellerna 1–3. Resultatet visar en stor mängd nya fordonslaster som definierats i FEM-Design efter trafikverkets standarder. Om programmet även lyckas tillämpa fler funktioner som är mer anpassade för att definiera laster, genom vidare studier kan FEM-design i framtiden vara mer konkurrenskraftigt med de andra brokonstruktionsprogrammen.

Abstract [en]

FEM-Design is generally used for structural design of buildings. This work aims to make the program more adaptable to bridge design. It is possible in this way that loads of military vehicles are modeled in FEM-Design. In this work Wheeled vehicles, tire vehicles, convoys have been modeled. A previous degree project on modeling of special vehicles and load modeling was checked in this work. It was made to ensure that they were modeled correctly. The loads were analyzed by inserting the modeled loads on a plate or a beam where the moment diagram would give the same result as if it had been made by hand. The military vehicle loads were calculated according to the Swedish transportation administration requirements and the result was defined in FEM-Design so that the result can be used for load modelling. The work together with Strusoft AB resulted in 128 new loads being modeled in FEM-Design. In addition, 30 already modeled special vehicle loads of load models 1-3 were checked. The result shows a large number of new vehicle loads that are defined in FEM-Design according to the Swedish Transport Administration's standards. If the program also manages to apply more functions that are more adapted to define loads, through further studies, FEM design in the future can be more competitive with the other bridge design programs.
