4. 3. 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.

5. 4. Analysis of geometrically modified adhesive joints in steel beams strengthened with composite laminates

   Författare :Reza Haghani Dogaheh; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FE analysis; Stress concentration; Fillet; Laminate; Reverse tapering; Normal tapering; Adhesive joint; FRP;

   Sammanfattning : The use of bonded FRP laminates to strengthen and upgrade existing structures has attracted a great deal of attention during the past two decades. The attractiveness of this method is mainly due to the superior material properties of FRP laminates such as high strength and stiffness, as well as advantages associated with the bonding technique, such as ease of application and good fatigue performance.

7. 5. Development of connections for fibre reinforced bridge elements and an analysis of sustainability

   Författare :Valbona Mara; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bridge; insert; connection; deck; FRP; bolt; joint; fibre reinforced polymer; LCC; LCA;

   Sammanfattning : The deterioration of existing bridge structures due to a number of causes has led researchersto pursue new construction materials with high performance, such as fibre reinforced polymer(FRP) composite materials. The inherent properties of FRP materials are their light weight,high strength and high resistance to aggressive environments. LÄS MER
