  3. 2. Strukturmekanik & arkitektur Om strukturmekanisk förståelse i gestaltningsprocessen

    Författare :Karl-Gunnar Olsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CALFEM; stiffness; structural mechanics; design; architecture; Architectural design process; pointSketch; ForcePAD; canonical stiffness; static eigenvalues;

    Sammanfattning : Organizing material to produce space and a load-carrying structure are central tasks in the architectural design process. In trying out and examining design ideas, use of language and tools appropriate to the purpose is fundamental. LÄS MER

  4. 3. Vibration Frequencies as Status Indicators for Tensegrity Structures

    Författare :Nasseradeen Ashwear; Anders Eriksson; Karl-Gunnar Olsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tensegrity; Pre-stress; Vibration; Health monitoring; Buckling; Temperature effect; Vibration health monitoring VHM; Tensegritet; Förspänning; Vibration; Hälsokontroll; Knäckning; Temperatureffekt; Vibrationsbaserad hälsokontroll; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning :  Applications of vibration structural health monitoring (VHM) techniques are increasing rapidly. This is because of the advances in sensors and instrumentation during the last decades. VHM uses the vibration properties to evaluate many civil structures during the design steps, building steps and service life. LÄS MER

  5. 4. Stiffness modification of tensegrity structures

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

    Sammanfattning : 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. LÄS MER
