  1. 1. I-girder Composite Bridges with Lateral Bracing : Improved load distribution

    Författare :Victor Vestman; Peter Collin; Robert Hällmark; Hans Petursson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; assessment; bridge; composite bridge; steel-concrete composite; I-girder; case study; horizontal trusses; lateral bracing; rehabilitation; strengthening; torsional stiffness; upgrading; Byggkonstruktion; Structural Engineering;

    Sammanfattning : This thesis deals with the subject of lateral bracing between the bottom flanges of I-girder composite bridges. The focus is on the impact of adding lateral bracing on existing bridges, as well as on new bridges. LÄS MER

  3. 2. Methods to assess physical load at work : With a focus on the neck and upper extremities

    Författare :Peter Palm; Mikael Forsman; Magnus Svartengren; Svend Erik Mathiassen; Eva Vingård; Esa Pekka Takala; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; risk assessment; physical load; upper extremities; ergonomics; Occupational and Environmental Medicine; Arbets- och miljömedicin;

    Sammanfattning : To prevent work-related musculoskeletal disorders (MSDs), useful, reliable and valid methods for assessing physical workload and risks for MSDs are needed. Ergonomists often assess work by short visual observations without a specific tool. LÄS MER

  4. 3. Environmental assessment of the urban environment

    Författare :Anna Forsberg; KTH; []
    Nyckelord :environmental assessment; urban district; environmental load profile; hammary sjöstad; life cycle assesssment;

    Sammanfattning : This thesis gives a systematic description of theEnvironmental Load Profile (ELP), an environmental assessmenttool developed for the urban environment. The purpose of thework was to improve the stringency of the system boundaries andfunctional units of the tool. LÄS MER

  5. 4. Concrete Bridges : Improved Load Capacity

    Författare :Jonny Nilimaa; Terje Kanstad; Luleå tekniska universitet; []
    Nyckelord :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

  7. 5. Assessment of Concrete Structures Including Corrosion and Cracks

    Författare :Mattias Blomfors; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforced concrete; corrosion; nonlinear FE analysis; reinforcement bond; assessment; cracks;

    Sammanfattning : Reinforced concrete (RC) structures constitute a major proportion of the built environment and society relies continuously on their service. Many of these structures were built in the era following the Second World War and are thus approaching the end of their intended service life. LÄS MER
