  1. 1. Sustainability and Flexural Behaviour of Textile Reinforced Concrete

    Författare :Natalie Williams Portal; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life Cycle Assessment LCA ; sustainability; Textile Reinforced Concrete; TRC; facade elements; flexural behaviour; non-linear finite element analyses; structural tests;

    Sammanfattning : Concrete reinforced with conventional steel is one of the most commonly used building materials, yet it has historically shown disadvantages in terms of durability and vulnerability to corrosion attack. Various remedial methods have been applied to overcome the shortcomings of this building material, such as increasing the concrete cover, which, however, leads to an increased self-weight of the structure.

  3. 2. Can Bone Void Fillers Carry Load? : Behaviour of Calcium Phosphate Cements Under Different Loading Scenarios

    Författare :Ingrid Ajaxon; Cecilia Persson; Caroline Öhman-Mägi; Uwe Gbureck; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Calcium phosphate; bone cement; brushite; apatite; monetite; porosity; solvent exchange; degradation; compressive strength; diametral tensile strength; flexural strength; elastic modulus; Poisson’s ratio; fatigue; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : Calcium phosphate cements (CPCs) are used as bone void fillers and as complements to hardware in fracture fixation. The aim of this thesis was to investigate the possibilities and limitations of the CPCs’ mechanical properties, and find out if these ceramic bone cements can carry application-specific loads, alone or as part of a construct.

  4. 3. Structural Behaviour of Concrete Railway Sleepers

    Författare :Rikard Gustavson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete; finite element analysis; three-wire strand; sleeper; bond; strand; pull-through tests; steel encased; push-in tests; bond mechanism; numerical bond model; dynamic loads;

    Sammanfattning : The railway concrete sleeper is an important part of the railway track structure. The sleeper member requires substantial engineering skills during the design and manufacturing process in order to fulfil the requirements set by modern train traffic. LÄS MER

  5. 4. Behaviour and resistance of composite slabs : experiments and finite element analysis

    Författare :Milan Veljkovic; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : Composite slab flooring systems are used in steel framed buildings as well as in conjunction with concrete, prestressed concrete and timber structures. Composite slabs consist of a thin-walled profiled steel sheet, reinforcement and in-situ cast concrete. LÄS MER

  7. 5. Behaviour and design of adhesive joints in flexural steel members bonded with FRP laminates

    Författare :Reza Haghani Dogaheh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laminate; Adhesive joint; Stress concentration; FRP; Design; Optic measurement; Fillet; Tapering;

    Sammanfattning : The use of bonded CFRP laminates to strengthen and upgrade existing structures has attracted a great deal of attention during the past two decades. The superior mechanical properties of CFRP laminates, such as high strength and stiffness, excellent fatigue properties and good durability characteristics, have made them a suitable alternative to steel plates used in traditional strengthening and repair methods.
