  1. 11. Vibration transfer process during vibratory sheet pile driving : from source to soil

    Författare :Fanny Deckner; Staffan Hintze; Kenneth Viking; Steinar Nordal; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ground vibrations; sheet piles; vibratory driving; vibration transfer process; instrumentation system; field tests; numerical modelling; vibration prediction; markvibrationer; spont; vibrodrivning; vibrationsöverföringsprocessen; instrumenteringssystem; fältförsök; numerisk modellering; vibrationsprognosticering; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : Vibratory driven sheet piles are a cost-effective retaining wall structure, and in coming decades the continued use of this method will be crucial for minimising costs within the construction sector. However, vibratory driven sheet piles are a source of ground vibrations, which may harm structures or induce disturbance. LÄS MER

  3. 12. Soil identification by vibration measurements during soil-rock sounding

    Författare :Editha Ehrmanntraut; Stefan Larsson; Jörgen Johansson; KTH; []

    Sammanfattning : Dynamic penetration tests are frequently used as geotechnical site investigation methods. In Sweden, the main reason to choose a dynamic penetration method is to investigatedepth to bedrock, strength and deformation properties of soil, compaction, or pilingdepth. LÄS MER

  7. 15. Computational Methods in Conceptual Structural Design

    Författare :Vedad Alic; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conceptual design; conceptual structural design; ground-borne vibrations; form finding; optimization; dynamic relaxation; graphic statics; reciprocal figures; strut-and-tie; finite element method; isogeometric analysis; NURBS; CAD; numerical modelling;

    Sammanfattning : Conceptual design is the first phase in the design process in which all the requirements and design objectives are synthesized into conceptual alternatives. In practice today, major decisions regarding the buildings function, massing, and overall form are usually made during the first phase. LÄS MER
