  1. 1. Design for Serviceability - A probabilistic approach

    Författare :Daniel Honfi; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design codes; long-term deflections; structural reliability; serviceability;

    Sammanfattning : In many design situations the acceptable performance of structures is defined by serviceability requirements. To estimate the probability of serviceability failure three main design aspects should be considered: (1) the relevant exposures, (2) the structural response and (3) the performance criteria.

  3. 2. Patch loading resistance of plated girders : ultimate and serviceability limit state

    Författare :Jonas Gozzi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : Patch loading or partial edge loading of steel girder webs is a load case where a concentrated force is introduced perpendicular to the flange of a girder. This usually induces a local failure of the girder web in the vicinity of the loaded flange. LÄS MER

  4. 3. Supportability Engineering in Wind Power Systems - Who Cares? : Considering important stakeholders and their requirements

    Författare :Renato Ciganovic; Per Anders Akersten; Marcus Bengtsson; Linnéuniversitetet; []
    Nyckelord :Supportability; Supportability Engineering; Stakeholders Requirements; Non-functional Requirements; Integrated Logistic Support; Asset Management; Maintenance Support; Logistic Support; Wind Energy; Wind Power; Accessibility; Maintainability; Serviceability; Supported System; Terotechnology; Systemekonomi;

    Sammanfattning : Wind power is one of the fastest growing energy sources, which have advantages in terms of delivering clean, cheap and fast energy. Many actors and organizations have realized this potential, which has lead to exponential growth of the wind power over recent couple of years. LÄS MER

  5. 4. Serviceability Limit State for Steel Girders during Bridge Launching - A Patch Loading Problem

    Författare :Per Granath; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel; patch loading; plate girders; bridge launching; post-buckling; behaviour; finite element analysis; serviceability limit state;

    Sammanfattning : Incremental launching is a construction method in which bridge girders are first assembled in the vicinity of the future permanent position of the bridge. When the elements have been welded together the girders are launched to their permanent position. LÄS MER

  7. 5. Shear cracks in concrete structures subjected to in-plane stresses

    Författare :Richard Malm; Håkan Sundquist; Kent Gylltoft; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shear; plane state stress; crack width; FE analysis; design standards; serviceability state; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : After only two years of service, extensive cracking was found in the webs of two light-rail commuter line bridges in Stockholm, the Gröndal and Alvik bridges. Due to this incident it was found necessary to study the means available for analysing shear cracking in concrete structures subjected to in-plane stresses. LÄS MER
