  1. 6. Dynamic analyses of structures with applied rubber

    Författare :Magnus Alvelid; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Viscoelasticity; Series expansion; Finite; Fractional calculus; Optimization;

    Sammanfattning : The aim with the present thesis has been to develop efficient, practical and accuratemethods in order to model rubber in dynamic analyses, with emphasis on passive constrainedlayer damping materials. A fractional order viscoelastic constitutive model ismapped onto experimental data from a measurement standard using a vibrating beamtechnique. LÄS MER

  3. 7. Application of Fracture Mechanics to Concrete Bridges. Finite element analyses and experiments

    Författare :Mario Plos; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

    Sammanfattning : Climate change and densification of cities are two major global challenges. Inthe building and construction industry, there are great expectations that tall timberbuildings will constitute one of the most sustainable solutions. First, verticalurban growth is energy and resource-efficient. LÄS MER
