  1. 6. Opportunities for Weight Reduction in Composite Marine Structures

    Författare :Luis Felipe Sanchez Heres; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; material characterization; ultimate limit state; composites; lightweight design; non-crimp fabrics;

    Sammanfattning : Composite marine structures are desirable for a variety of reasons. Compared to traditional steel structures, they enable the construction of vessels with lower fuel consumption, higher top speed, better stability, lower maintenance, higher cargo capacity, or combinations thereof.

  3. 7. Strengthening steel beams with adhesively bonded composite laminates

    Författare :Dag Linghoff; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFRP laminate; adhesive bond; interfacial stresses.; Strengthening;

    Sammanfattning : Strengthening steel structures with carbon-fibre-reinforced-polymer (CFRP) laminates bonded to the steel substrate has become an interesting alternative to the conventional strengthening methods. The current research comprises analyses of the global and local behaviour of double-symmetrical steel beams strengthened with CFRP laminate bonded with adhesive to the tension flange. LÄS MER

  4. 8. Prefabricated composite bridges : a study of dry deck joints

    Författare :Robert Hällmark; Ian May; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bridge construction; prefabrication; monitoring; Steel Structures; Stålbyggnad;

    Sammanfattning : This thesis deals with prefabricated composite bridges in general, and prefabricated concrete deck elements with dry joints in particular.As outlined in Paper I and Chapter 2 prefabrication has several advantages over in situ construction, and has hence been discussed for decades in the construction business.

  5. 9. Composite Columns of Hollow Steel Sections Filled with High Strength Concrete

    Författare :Marianne Grauers; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In the design of buildings today, great effort is made to increase the structural flexibility. This has resulted in a demand for columns with reduced cross sections. To achieve a high load bearing capacity with a small cross sectional area, it is worthwhile to study the possibility of utilizing high strength concrete and composite effects. LÄS MER

  7. 10. Industrial Fibre Concrete Floors : Experiences and Tests on Pile-Supported Slab

    Författare :Jerry Hedebratt; Johan Silfwerbrand; Terje Kanstad; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Pile supported floor slabs have often been designed solely in ultimate limit state ULS and then foremost with uniformly distributed loadings UDL. The investigation of serviceability limit state SLS has been of simpler nature, even according to the governing codes of practice. LÄS MER
