  1. 1. Computational modeling strategy of steel connections

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

    Author : Carl-Michael Bjälkensäter; Carl Holmgren; [2019]
    Keywords : FEM; steel; connection; joint; Technology and Engineering;

    Abstract : When designing large complex steel structures numerical calculation methods are always used to some extent. The simulation technology of today is advanced and can with proper modeling technique provide detailed analyses which captures the structural response accurately. READ MORE

  2. 2. Optimization of diagonal stiffeners to handle wind pressures on silos

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Max Hellberg; [2019]
    Keywords : ;

    Abstract : In this report the focus is set on how to optimize the support structure of a silo and in particular, the stiffeners and fastener. The main force of the silo comes from the wind pressures. The design is subjected to the Swedish and European standards SS-EN 199-1-4:2005, 1993-1-1:2005 and 1990. READ MORE

  3. 3. Global stability of high-rise buildings on foundation on piles

    University essay from KTH/Bro- och stålbyggnad; KTH/Bro- och stålbyggnad

    Author : Husein Dhorajiwala; Agnieszka Owczarczyk; [2018]
    Keywords : High-rise buildings; Tall buildings; Buckling; Global Stability; Foundation; Straight piles; Inclined piles;

    Abstract : In Sweden as well as other countries the trend of building higher is more and more popular. The global stability of tall buildings is a very important aspect that has to be taken into account while designing. Foundation on piles, that is common in Sweden, reduces the global stability compared to foundation directly on bedrock. READ MORE

  4. 4. Buckling of End-Bearing Retaining Walls in Clay

    University essay from KTH/Jord- och bergmekanik; KTH/Jord- och bergmekanik

    Author : Fredrik Jansson; Nils Nilsson; [2018]
    Keywords : Berliner walls; Critical loads; buckling; finite element model; Eurocode 3; Berlinerspont; Rörspont; kritisk knäckningslast; knäckning; finit element modell; Eurocode 3;

    Abstract : The design of back-anchored retaining walls in Sweden has traditionally not included global elastic instability of the retaining wall as a possible failure mode. Eurocode 3 part 5 (SS-EN 1993-5) requires design of steel structural members for retaining walls to assess the risk of buckling if the normal force exceeds 4 % of the critical buckling load of the retaining wall.

  5. 5. Analytical calculation model used when dimensioning timber poles used as overhead power line supports

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Christopher Ekängen; [2018]
    Keywords : Calculation model; timber poles; overhead power line;

    Abstract : Overhead power lines are more reliable and cost effective than underground cables when it comes to power transmission. The overhead power lines are often suspended above ground using timber pole supports. READ MORE
