  1. 1. Modelling of Traffic Loads on Bridges Based on Measurements of Real Traffic Loads in Sweden

    Författare :Fredrik Carlsson; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heavy vehicles; traffic intensity; Peaks Over Thresholds; axle and bogie pressure; traffic load effects; probability based classification; Technological sciences; Teknik;

    Sammanfattning : This thesis treats traffic load effects in road bridges and in particular bending moment and shear force in different types of bridges. All traffic load effects are described in terms of statistical distribution functions for annual extreme values. LÄS MER

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

    Författare :Abraham Getachew; KTH; []
    Nyckelord :bridge; traffic load; transverse distribution; characteristic value; weigh in motion;

    Sammanfattning : 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. LÄS MER

  3. 3. Analysis of traffic load effects an railway bridges

    Författare :Gerard James; KTH; []
    Nyckelord :bridge; rail; traffic load. Load effect. Dynamic amplification factor; extreme value theor; peaks-over-threshold;

    Sammanfattning : The work presented in this thesis studies the load and loadeffects of traffic loads on railway bridges. The increasedknowledge of the traffic loads, simulated using fieldmeasurements of actual trains, are employed in a reliabilityanalysis in an attempt at upgrading existing railwaybridges. LÄS MER

  4. 4. Future Train Traffic Control : Development and deployment of new principles and systems in train traffic control

    Författare :Gunnika Isaksson-Lutteman; Bengt Sandblad; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap med inriktning mot människa-datorinteraktion; Computer Science with specialization in Human-Computer Interaction;

    Sammanfattning : The train traffic control system of the future requires new solutions and strategies in order to better meet tomorrow’s demands and goals. Uppsala University and Trafikverket have been collaborating for several years in research regarding train traffic control and how to improve traffic controllers’ support systems and working environment.

  5. 5. Concrete Bridges : Improved Load Capacity

    Författare :Jonny Nilimaa; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : There are many beautiful old structures around the world, some of which were designed for completely different purposes than their current applications. For example, Swedish railway bridges were only designed to carry axle loads up to 200 kN in the beginning of the 20th century, while modern loads can be twice as high. LÄS MER
