1. 1. Strengthening reinforced concrete structures with FRP composites

   Författare :Jincheng Yang; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GFRP; finite element analysis.; corrosion; interfacial stress; externally bonded reinforcement; self-anchorage; CFRP; debonding; concrete structures; Fibre reinforced polymer; prestressing level;

   Sammanfattning : Civil infrastructures made of reinforced concrete (RC) play an important role in the economic activities and services of society. However, signs of deterioration and functional deficiency are commonly found in existing RC structures. Thus, there is a great demand for upgrading the capacity and performance of existing concrete structures. LÄS MER

3. 2. Plate bonding : strengthening of existing concrete structures with epoxy bonded plates of steel or fibre reinforced plastics

   Författare :Björn Täljsten; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

   Sammanfattning : This thesis deals with several aspects of the plate bonding problem, i.e. when steel or fibre reinforced plastics (FRP) plates are bonded to a concrete structure with the use of an epoxy adhesive. Both theoretical work and laboratory tests are presented as well as a full scale test on a strengthened concrete bridge. LÄS MER

4. 3. Strengthening of timber structures with flax fibres

   Författare :Alann Andre; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

   Sammanfattning : The natural defects present in timber are the source of large variations in mechanical properties. This drawback has been partially counteracted with the use of Engineered Wood Products EWP (glulam, composite I-beam, parallel strand lumber, etc.) instead of solid wood. LÄS MER
