2. 11. Application of Fracture Mechanics to Concrete Bridges. Finite element analyses and experiments

   Author : Mario Plos; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforced concrete; reinforcement splice; full-scale test; shear failure; fracture mechanics; fatigue test; static test; concrete frame corner; non-linear finite element analysis; concrete bridge;

   Abstract : Material models based on fracture mechanics together with non-linear finite element analyses have been used in combination with experiments to study the behaviour of reinforced concrete bridges. The work covers two aspects of interest in the design of concrete bridges.* The shear behaviour was studied in full-scale tests on two highway bridges. READ MORE

4. 12. Concrete Structures Subjected to Blast Loading

   Author : Jonas Ekström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic response; numerical modelling; spalling; blast load; stain-softening; wave propagation; concrete; transverse reverse loading; cyclic crack propagation;

   Abstract : The interest for building safety with regards to highly dynamic events such as close by explosion has accelerated after the recent decades of terrorist attacks. The interest has expanded from civil defence shelters and pure military targets to also include civil buildings used for different civil functions. READ MORE

5. 13. Fibre-reinforced Concrete for Industrial Construction - a fracture mechanics approach to material testing and structural analysis

   Author : Ingemar Lövgren; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in-situ cast; non-linear; self-compacting; fibre-reinforced; concrete;

   Abstract : ABSTRACTMore efficient and industrialised construction methods are both necessary for thecompetitiveness of in-situ concrete and essential if the construction industry is to moveforward. At present, the expenditure on labour (preparation and dismantling offormwork, reinforcing, and casting and finishing of concrete) almost equals the cost ofmaterial. READ MORE

6. 14. Novel approaches for monitoring effects of steel corrosion in reinforced concrete

   Author : Andreas Alhede; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reinforced Concrete; Neutron and X-ray Computed Tomography; Corrosion; Distributed Optical Strain Sensing;

   Abstract : Corrosion of steel reinforcement is a common deterioration mechanism in reinforced concrete structures. This deterioration impacts the safety of the structure and may require extensive repair and maintenance work. There is currently no method available for accurately measuring internal corrosion damage non-destructively. READ MORE

7. 15. A NEW APPROACH TO CRACK CONTROL FOR REINFORCED CONCRETE - An investigation of crack widhts close to the reinforcement and the correlation to service life

   Author : Kristian Tammo; Avdelningen för Konstruktionsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete cover; corrosion; Crack width; steel stress and service life;

   Abstract : One of the most important factors governing durability of concrete structures is reinforcement corrosion, and to prevent degradation associated with it, it is desirable to use large concrete covers. However, if the concrete cover is increased, the majority of design methods will predict that the crack widths at the concrete surface increase significantly. READ MORE
