  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

  4. 2. Hybrid and Dynamic Substructuring Methods for Energy Flow Analysis

    Author : Anders Wilson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fractional derivatives; structural modeling; mid-frequency; finite element method FEM; vibro-acoustics; statistical energy analysis SEA; dynamic substructuring; hybrid analysis; viscoelasticity;

    Abstract : Modeling techniques and solution tools to analyze the dynamic and vibro-acoustic behavior of complex built-up structures are matters of increasing interest, especially for thin walled structures as in transportation vehicles, such as automobiles, trucks, trains and aircraft. In structures like these, the reduction of cost, weight, sound and vibration levels are primary issues for research and development. READ MORE

  5. 3. Timber-concrete hybrid structural systems : Examples, long and short-term dynamic monitoring, and numerical analysis

    Author : Carl Larsson; Michael Dorn; Åsa Bolmsvik; Thomas K. Bader; Henrik Danielsson; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Timber-Concrete Hybrid Structures; Timber Design; Structural Dynamics; Structural Health Monitoring; Byggteknik; Civil engineering;

    Abstract : Timber-concrete hybrid buildings are an innovative solution to increase the amount of timber materials in modern buildings. Due to its lower impact on the environment than materials like steel and concrete, the demand for timber products is rising as the construction industry aims to decrease its environmental footprint.

  7. 5. Computational Methods in Conceptual Structural Design

    Author : Vedad Alic; Byggnadsmekanik; []
    Keywords : 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;

    Abstract : 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. READ MORE
