  1. 11. Realistic Modeling of Thermal Effects in Concrete Bridges

    University essay from Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Avdelningen för Konstruktionsteknik

    Author : Carl Larsson; Gustav Svensson; [2013]
    Keywords : Temperature; Thermal; Eurocode; Simulation; Realistic; Concrete; Bridge; Modeling; Effects; Cracking; Load; Design; Technology and Engineering;

    Abstract : Thermal actions have a signicant eect on bridge structures and can at some sections account for more than 20% of the reinforcement. Such actions are especially important in certain types of concrete bridges, e.g. portal frame bridges. READ MORE

  3. 12. Design and optimization of steel portal frames according to Eurocode using genetic algorithm

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Ghassan Numan; [2012]
    Keywords : Technology and Engineering;

    Abstract : One of the essential engineer’s jobs is to achieve the most economical technical solutions. Weight optimization is important since it provides a structure that can carry the applied loads in addition to fulfilling the structural requirements. READ MORE

  4. 13. Design Method for Strut-Beam Connection in Hinged Frames

    University essay from Lunds universitet/Byggnadsmekanik

    Author : Juan Cardenal; [2012]
    Keywords : ABAQUS; LEFM; failure modes; three-pin portal frames; shear stress; built-up haunches; framed joint; glulam; size effects; Technology and Engineering;

    Abstract : Glulam is almost exclusively the chosen material of timber frame structures. Of those, three-hinged (three-pin) portal frames are incomparably the most common type. Being both statically determinate and stable against horizontal forces in its own plane offer both practical (basic constructive details) and economical benefits. READ MORE

  5. 14. Dynamic analysis of soil-steel composite bridges for high speed railway traffic : Case study of a bridge in Märsta, using field measurements and FE-analysis

    University essay from KTH/Bro- och stålbyggnad

    Author : Peyman Mellat; [2012]
    Keywords : Soil-Steel Composite Bridge; Flexible Corrugated Steel Culvert; Structural Dynamics; Acceleration; High-Speed Trains; Field Measurement; FEM;

    Abstract : Soil-steel composite bridge refers to structures where a buried flexible corrugated steel pipe works in composite action with the surrounding soil. These structures are being increasingly used in road and railway projects as an alternative to standard type bridges, e.g. short- and medium span concrete beam- and portal frame bridges. READ MORE

  6. 15. Traffic induced vibrations on a portal frame railway bridge : Comparison of theory and measurements

    University essay from KTH/Bro- och stålbyggnad; KTH/Järnvägsgruppen, JVG

    Author : Andrea Llorens García; [2011]
    Keywords : Frame bridge; Dynamics; Support stiffness; High speed train; Ballast instability; Moving loads;

    Abstract : The effect of different vertical support stiffness of a frame railway bridge is investigated in this study. Due to the dynamic loads of the high speed trains that run over the railway bridges, the response of these structures is far from the static effects. READ MORE
