  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; Luleå tekniska universitet.; [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; Lunds universitet.; Lund University.; [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. 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; Lunds universitet.; Lund University.; [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

  4. 4. Durability of fire exposed concrete Experimental Studies Focusing on Sti„ffness & Transport Properties

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Joakim Albrektsson; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete; Fire; Polypropylene fibres; Durability; Tunnel; Damage assessment; Ultrasonic pulse velocity; Water absorption; Chloride migration; DIC; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Road and rail tunnels are important parts of the modern infrastructure. High strength concrete (HSC) is commonly used for tunnels and other civil engineering structures, since it allows high load carrying capacity and long service life. In general, Swedish road and rail tunnels should be designed for a service life of 120 years. READ MORE

  5. 5. Innovative structural details using high strength steel for steel bridges

    University dissertation from Stockholm : Kungliga Tekniska högskolan

    Author : Oskar Skoglund; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High strength steel; fatigue; steel bridges; steel and concrete composite bridges; innovative steel details; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Abstract : The use of high strength steel has the potential to reduce the amount of steel used in bridge structures and thereby facilitate a more sustainable construction. The amount of steel and what steel grade that can be used in bridge structures and other cyclic loaded structures are often limited by a material degradation process called fatigue. READ MORE
