  1. 1. Anchorage in Concrete Structures Numerical and Experimental Evaluations of Load-Carrying Capacity of Cast-in-Place Headed Anchors and Post-Installed Adhesive Anchors

    University dissertation from Luleå : Luleå University of Technology

    Author : Rasoul Nilforoush; Lennart Elfgren; Norbert Randl; Karin Lundgren; Manouchehr Hassanzadeh; Richard Malm; Lars-Erik Persson; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Headed anchor; Anchor bolt; Adhesive anchor; Concrete cone breakout; Concrete splitting; Pullout loading; Size effect; Member thickness; Anchor head size; Orthogonal surface reinforcement; Concrete Strength; High-strength concrete; Cracked concrete; Steel fiber-reinforced concrete; Sustained loading; Creep behavior; Structural Engineering; Konstruktionsteknik;

    Abstract : Various anchorage systems including both cast-in-place and post-installed anchors have been developed for fastening both non-structural and structural components to concrete structures. The need for increased flexibility in the design of new structures and strengthening of existing concrete structures has led to increased use of various metallic anchors in practice. READ MORE

  2. 2. Quasi-instantaneous and Long-term Deformations of High-Performance Concrete with Some Related Properties

    University dissertation from Division of Building Materials, LTH, Lund University

    Author : Bertil Persson; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shrinkage; Relative humidity; Long-term; Hydration; High-Performance Concrete; Elastic modulus; Deformations; Creep; Concrete; Cement; Quasi-instantaneous; Strength; Building construction; Byggnadsteknik;

    Abstract : This report outlines an experimental and numerical study on quasi-instantaneous and long-term deformations of High-Performance Concrete, HPC, with some related properties. For this purpose about two hundred small cylinders and about one thousand cubes of eight types of HPC were cast. The age at loading varied between 18h and 28 days. READ MORE

  3. 3. Bond and Anchorage of Ribbed Bars in High-Strength Concrete

    University dissertation from Division of Building Materials, LTH, Lund University

    Author : Jonas Magnusson; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-linear finite element analysis; high-strength concrete; anchorage; ribbed bars; beam tests; bond; confinement; normal strength concrete; pull-out tests;

    Abstract : For structural utilisation of high-strength concrete, a good understanding of the bond and anchorage behaviours of ribbed bars in this specific material is essential. The research project aims to increase the knowledge of bond and anchorage behaviours of ribbed bars in high-strength concrete. READ MORE

  4. 4. Structural Behavior of Reinforced High-Strength Concrete Columns

    University dissertation from Division of Building Materials, LTH, Lund University

    Author : Christina Claeson; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sustained loading; columns; slenderness; finite element analyses; nonlinear fracture mechanics; high-strength concrete; short-term loading; eccentricity;

    Abstract : The high compressive strength of high-strength concrete is especially advantageous in compressed members such as columns, which can be made more slender and, consequently, make economic benefits possible. However, the behavior of high-strength concrete columns is not yet fully understood. READ MORE

  5. 5. High-performance and self-compacting concrete in house building. Field tests and theoretical studies of possibilities and difficulties

    University dissertation from Division of Building Materials, LTH, Lund University

    Author : Markus Peterson; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-storey residential buildings; Structural frames; SCC; Self-compacting concrete; High-performanceconcrete; HPC; Concrete; Building materials; Cast in-situ concrete;

    Abstract : Cast in-situ concrete is the most frequently used materials technology worldwide within production of structural frames in multi-storey residential buildings. In Sweden, this technology dominates the market but is challenged by other competitive production methods. READ MORE
