  2. 1. Strengthening steel beams with adhesively bonded composite laminates

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

    Abstract : 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. READ MORE

  4. 2. Steel members strengthened with carbon fibre reinforced polymers - A study of local and global structural behaviour

    Author : Dag Linghoff; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforcement; CFRP laminate; adhesive; design;

    Abstract : Investigations have been conducted by several research groups to study the effect of using carbon fibre reinforced polymers (CFRP) as reinforcement on steel beams and a brief summary of this work is given in this thesis. Laboratory studies of reinforced steel beams demonstrate that the bending stiffness and the ultimate load-carrying capacity can be significantly increased. READ MORE

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

    Author : Reza Haghani Dogaheh; Chalmers tekniska högskola; []

    Abstract : 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.

    Abstract : A large number of existing bridges in European countries are structurally deficient and functionally obsolete due to the deterioration of aging bridges and the lack of structural and geometric capacity to accommodate the increasing traffic volume and load levels. To meet the demand for holistic and effective strengthening techniques the SUREBRIDGE solution is proposed for the refurbishment of concrete bridges, which includes the technique of using prestressed carbon fiber reinforced polymer (CFRP) laminate as externally bonded reinforcement for flexural strengthening.

    Abstract : The focus of this thesis is to develop methods to predict the damage response of Carbon Fibre Reinforced Polymers (CFRP). In the pursuit of reducing the manufacturing cost and weight of CFRP components, it is crucial to enable modelling of the non-linear response associated with various failure modes. READ MORE
