  1. 6. Durability and Long-term Performance of Adhesively Bonded FRP/steel Joints

    Författare :Mohsen Heshmati; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FRP steel joints; durability; fibre reinforced polymer; cohesive zone modelling; long-term performance; adhesively bonded joints; moisture diffusion;

    Sammanfattning : Fibre reinforced polymer (FRP) composites offer excellent properties, such as high specific strength and stiffness, corrosion resistance and light weight. Over the past four decades, FRPs have been increasingly used for strengthening and repair of bridge structures, and more recently, in the manufacture of whole/hybrid FRP bridges. LÄS MER

    Författare :Petr Sejkot; Petr Kuklík; Miloš Drdácký; Antonín Lokaj; Czech Republic Czech Technical University in Prague; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; angle brackets with a rib; annular ring nails; metal works for timber structures; static load tests of joints; numerical simulations of tests of joints; analytical static models of joints.; úhelníky s prolisem; kroužkové konvexní hřebíky; kování pro přípoje dřevostaveb; statické zatěžovací zkoušky přípojů; numerické simulace zkoušek přípojů; analytické statické modely přípojů.;

    Sammanfattning : The thesis deals with appropriate methods to determinate load-bearing capacities of timber structures joints using angle brackets with a rib. In these joints, annular ring nails were used as connectors.During an experimental approach, full-scale load tests of whole joints were performed. LÄS MER

  4. 8. Quality aspects in direct shear testing of rock joints

    Författare :Jörgen Larsson; Fredrik Johansson; Alejano Leandro; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rock joints; geometrical quality assurance; replicas; direct shear testing; normal stiffness; bergssprickor; geometrisk kvalitetssäkring; replikor; skjuvhållfasthetprovning; normalstyvhet.; Jord- och bergmekanik; Soil and Rock Mechanics;

    Sammanfattning : The stability of rock masses is influenced by the occurrence of rock joints. Therefore, the shear strength of rock joints must be considered in dimensioning of underground constructions. LÄS MER

  5. 9. In-plane tension behaviour of masonry

    Författare :Miklos Molnar; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; restrained shrinkage; cracking; movement joints; Building construction; mortar joints; KstrMasonry; masonry; in-plane tension; Byggnadsteknik; murverk; sprickor; krympning; dilatationsfogar;

    Sammanfattning : The main purpose of the present work is to increase knowledge of in-plane tension behav-iour of masonry and develop a model able to describe the impact of parameters influencing cracking caused by restrained shrinkage. In the process the mechanism of load transfer between units and mortar joints is described. LÄS MER

  7. 10. Connections for Timber-Framed Structures - Assembly Properties and Structural Behaviour

    Författare :Dan Engström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; frames; nails; connections; structures; interaction; glue; assembly; timber; economy; semi-rigidity; adhesive; joints; splices;

    Sammanfattning : By tradition, the design and development of connections has focused on the optimization of strength and stiffness. The subject of this thesis is the interaction between the assembly and structural properties of connections for timber-framed structures. LÄS MER
