  1. 1. Modelling Alternative Load Paths in Platform-Framed CLT Buildings : A Finite Element Approach

    Author : Johannes Albert Josef Huber; Mats Ekevad; Ulf Arne Girhammar; Sven Berg; Sigurdur Ormarsson; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; timber; robustness; finite element method; alternative load paths; disproportionate collapse; Träteknik; Wood Science and Engineering;

    Abstract : Timber has become more popular as a construction material during recent years. Engineered wood products, such as glued laminated timber and cross-laminated timber, have enabled the construction of multi-storey buildings. Tall buildings with many occupants need to resist a disproportional collapse in case of unexpected exposures, e.g. READ MORE

  2. 2. Development and application of corotational finite elements for the analysis of steel structures in fire

    Author : Luca Possidente; Jean-Marc Battini; Nicola Tondini; Paulo Vila Real; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Thermomechanical finite element; Shell element; 3D beam element; Steel structures; Buckling; Fire Safety Engineering; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Abstract : The ignition and the propagation of a fire inside a building may lead to global or local structural collapse, especially in steel framed structures. Indeed, steel structures are particularly vulnerable to thermal attack because of a high value of steel conductivity and of the small thickness that characterise the cross-sections. READ MORE

  3. 3. Structural Earthquake Response Analysis

    Author : Hamid Movaffaghi; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element method; Earthquake excitation; global and local optimization; viscoelastic passive dampers; stochastic simulation; structural earthquake response analysis;

    Abstract : AbstractEarthquakes are one of the most dangerous natural phenomena causing damage to buildings and other structures as well as injury and death of people. These destructive processes can never be prevented to happen, but their impact on the structures can be minimized. READ MORE

  4. 4. Corotational formulation for nonlinear analysis of flexible beam structures

    Author : Thanh Nam Le; Jean-Marc Battini; Jari Mäkinen; KTH; []
    Keywords : Corotational method; nonlinear dynamic analysis; beam element; large displacements; finite rotations; time stepping method; cubic interpolations;

    Abstract : Flexible beam structures are popular in civil and mechanical engineering. Many of these structures undergo large displacements and finite rotations, but with small deformations. Their dynamic behaviors are usually investigated using finite beam elements. A well known method to derive such beam elements is the corotational approach. READ MORE

  5. 5. Resistance of Circular and Polygonal Steel Towers for Wind Turbines : Down scale component experiments and Finite element analysis

    Author : Anh Tuan Tran; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : With increasing demand of sustainable energy production, the harvesting of wind power by using wind turbines have become increasingly important over the last few decades. Most of the wind turbine towers are made from steel. Towers are an important part of the investment in wind parks and contribute about 20% of costs for the onshore towers. READ MORE
