  1. 1. Bridge Monitoring to Allow for Reliable Dynamic FE Modelling A Case Study of the New Årsta Railway Bridge

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Johan Wiberg; KTH.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bridge monitoring; FE modelling; signal analysis; torsion; warping; modulus of elasticity; natural frequency; damping; finite differences; TECHNOLOGY Civil engineering and architecture; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur;

    Abstract : Today’s bridge design work in many cases demands a trustworthy dynamic analysis instead of using the traditional dynamic amplification factors. In this thesis a reliable 3D Bernoulli-Euler beam finite element model of the New Årsta Railway Bridge was prepared for thorough dynamic analysis using in situ bridge monitoring for correlation.

  2. 2. Traffic Load Effects on Bridges, Statistical Analysis of Collected and Monte Carlo Simulated Vehicle Data

    University dissertation from Stockholm : Byggvetenskap

    Author : Abraham Getachew; KTH.; [2003]
    Keywords : bridge; traffic load; transverse distribution; characteristic value; weigh in motion;

    Abstract : Research in the area of bridge design has been and still isconcentrated on the study of the strength of materials andrelatively few studies have been performed on traffic loads andtheir effects. Traffic loads have usually been assumed to begiven in codes. READ MORE

  3. 3. Shear and Torsion in Concrete Structures Non-linear Finte Element Analysis in Design and Assessment

    University dissertation from Stockholm : Byggvetenskap

    Author : Helén Broo; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; torsion; box-girder bridge; hollow core unit; hollow core floor; non-linear finite element analysis.; shear; prestressed concrete; Reinforced concrete;

    Abstract : For structural design and assessment of reinforced concrete members, non-linear finite element analysis has become an important tool. However, design and assessment of shear and torsion are still done with simplified analytical or empirical design methods. READ MORE

  4. 4. Climate Related Thermal Actions for Reliable Design of Concrete Structures

    University dissertation from Stockholm : Byggvetenskap

    Author : Oskar Larsson; Lund University.; Lunds universitet.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal stress; solar radiation; FE-analysis; climate data; box-girder bridge; KstrConcrete; KstrReliability;

    Abstract : When the temperature changes in the environment the temperature will also change in a structure. Complex interactions of climate factors affect the temperature changes. When the temperature is varied in a material it will expand or contract, and movements will be produced. READ MORE

  5. 5. Life cycle assessment of bridges, model development and case studies

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Guangli Du; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainable construction; Life cycle assessment; LCA; Global warming; Bridge LCA; CO2 emissions; Cumulative energy demand; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : In recent decades, the environmental issues from the construction sector have attracted increasing attention from both the public and authorities. Notably, the bridge construction is responsible for considerable amount of energy and raw material consumptions. READ MORE
