  2. 1. Dynamic properties of two pedestrian timber bridges : Experimental and numerical analysis at several stages of construction

    Author : Jens Bergenudd; Jean-Marc Battini; Roberto Crocetti; Patricia Hamm; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic analysis; Modal analysis; Pedestrian bridge; Timber; Railings; Asphalt; Slip modulus; Finite element modelling; Dynamisk analys; Modal analys; Gång- och cykelbro; Trä; Räcken; Asfalt; Förskjutningsmodul; Finita element modellering.; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Abstract : Pedestrian bridges can beneficially be made from timber in order for our society to reach a sustainable future. This positive development is partly made possible due to advances in engineered wood products (e.g. glued laminated timber) and the possibilities for pre-fabrication of structural parts. READ MORE

    Abstract : 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. READ MORE

  5. 3. Probabilistic Analysis and Reliability of Engineering Structures

    Author : Anders Olsson; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building construction; Byggnadsteknik; roof truss; racking system; importance sampling; Latin hypercube sampling; reliability;

    Abstract : This thesis, consisting of six papers, concerns methods for probabilistic analysis of engineering structures. The work comprises evaluations of available methods, developments of new and improved methods, and applications of probabilistic analysis to engineering structures. READ MORE

  6. 4. Stiffness modification of tensegrity structures

    Author : Seif Dalilsafaei; Anders Eriksson; Karl-Gunnar Olsson; KTH; []
    Keywords : tensegrity; boom; finite element analysis; genetic algorithm; flexibility analysis; active structure; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Although the concept of tensegrity structures was invented in the beginning of the twentieth century, the applications of these structures are limited, partially due to their low stiffness. The stiffness of tensegrities comes from topology, configuration, pre-stress and initial axial element stiffnesses. READ MORE

  7. 5. Stiffness and vibration properties of slender tensegrity structures

    Author : Seif Dalil Safaei; Gunnar Tibert; René Motro; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tensegrity booms; Tensegrity grids; Tensegrity power lines; Finite element analysis; Genetic algorithm; Flexibility analysis; Form-finding; Pre-stress design; Optimization;

    Abstract : The stiffness and frequency properties of tensegrity structures are functions of the pre-stress, topology, configuration, and axial stiffness of the elements. The tensegrity structures considered are tensegrity booms, tensegrity grids, and tensegrity power lines.A study has been carried out on the pre-stress design. READ MORE
