  1. 1. Cracking in concrete : crack prevention with air-cooling and crack distribution with steel fibre reinforcement

    Author : Patrik Groth; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : This Licentiate Thesis consists of four parts. The first two parts, paper A and B, deal with air-cooling by means of embedded pipes in order to reduce thermal cracking in concrete structures. These two papers are submitted for publication to RILEM Journal; ‘Materials and Structures'. READ MORE

  2. 2. Ductility in high performance concrete structures : an experimental investigation and a theoretical study of prestressed hollow core slabs and prestressed cylindrical poles

    Author : Henrik Gabrielsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : The thesis presents results from a project dealing with ductility in high performance concrete structures. The main objectives were to investigate the material and structural ductility/brittleness of prestressed structural elements of High Performance Concrete (HPC). READ MORE

  3. 3. 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

  4. 4. Assessment of fatigue resistance and strength in existing concrete structures

    Author : Håkan Thun; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : During the last few decades, it has become more and more important to assess, maintain and strengthen structures like bridges, dams and buildings. This is mainly due to the fact that: (a) many structures are getting old and many have started to deteriorate, (b) there is sometimes a need to increase the load carrying capacity of an existing structure due to e.

  5. 5. Mechanical Characterization of Engineering Materials by Modal Testing

    Author : Daniel Larsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; material variability; modal testing; non-destructive test methods; damping ratios; timber beams; plastic panels; aluminium panel; elastic constants; concrete curing; wood-based panels; solids; high-strength concrete; anisotropic materials;

    Abstract : This thesis deals with the use of modal testing for establishing elastic constants of engineering materials and for indicating material variability in terms of stiffness and damping properties. The methodology using modal testing techniques, is applied to timber beams, high strength concrete prisms, wood-based panels (oriented strand board and chipboard), an aluminium alloy panel and plastic laminate panels (high-pressure laminate).
