  1. 21. Temperature analysis of fire exposed load-bearing structures of mono glazed balconies

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Andreas Lilja; [2020]
    Keywords : CFD; FDS; FEM; TASEF; EKS; Eurocode; Simulation; Fire; Balcony; CFD; FDS; FEM; TASEF; EKS; Eurokoderna; Simulering; Brand; Balkong;

    Abstract : Previous to the now acting construction regulations EKS and Eurocode, the fire resistance of the load-bearing structures of mono glazed balconies were designed with a fire test called the SP fire 105. In 2011, when EKS replaced the previous construction regulations called Boverkets konstruktionsregler, BKR, the SP fire 105 was no longer the requirement for mono glazed balconies. READ MORE

  3. 22. Reinforced Concrete Structures Subjected to Imposed Deformations: A Study of Cracking due to Shrinkage in Slab Foundations for Residential Houses

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologi

    Author : Henrik Johansson; Martin Heinegård; [2020]
    Keywords : Reinforced concrete structures; nonlinear finite element analysis; crack widths; imposed deformations; shrinkage; foundation slabs; fracture mechanics; Atena 2D; Technology and Engineering;

    Abstract : The need for limiting crack widths in reinforced concrete structures is due to durability, tightness towards gaseous and liquid substances, and for aesthetic reasons. Although concrete cracks at relatively low tensile stresses and can not be avoided, strategies for crack control can be adopted to meet the requirements. READ MORE

  4. 23. Dynamic analyses of hollow core slabs : Experimental and numerical analyses of an existing floor

    University essay from KTH/Bro- och stålbyggnad

    Author : Markus Hansell; Panagiotis Tamtakos; [2020]
    Keywords : Hollow core slab; Structural dynamics; Signal analysis; Mode shape; Frequency response function; Complex mode; FE-model; Håldäcksbjälklag; Strukturdynamik; Signalanalys; Modform; Frekvenssvar; Komplex mod; FE-modellering.;

    Abstract : For intermediate floors in residential and office buildings, as well as in parking garages and malls, there is a wide use of hollow core concrete slabs in Sweden today. Hollow core slabs are precast and prestressed concrete elements with cylindrical-shaped voids extending along the length of the slab. READ MORE

  5. 24. Concrete floor : Design of prefabricated pre-stressed hollow core slabs with verification through PRE-Stress and comparison with site-cast slab

    University essay from KTH/Byggteknik och design

    Author : Alexander Eriksson; Veronica Flykt; [2020]
    Keywords : Pre-stressed hollow core slab; site-cast slab; design; concrete; Förspända håldäcksplattor; platsgjutet bjälklag; dimensionering; betong;

    Abstract : The most common prefabricated concrete slabs are hollow core slabs, which are usually pre-tensioned. How to design these parts is not compiled today in a manual where it is clear how this is done, this knowledge is generally classified as expert knowledge. READ MORE

  6. 25. Climate Change Mitigation Measures of Load-Bearing Structure - A comparison of alternative structural designs using Life Cycle Assessment

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

    Author : Mirass Jalil; [2020]
    Keywords : Life Cycle Assessment; LCA; Load-Bearing Structure; Livscykelanalys; Byggnadsstomme; stomalternativ; structural engineering; span length; cross-section depth; precast concrete slab; in-situ concrete slab.; Technology and Engineering;

    Abstract : I mars 2015 nådde den globalt genomsnittliga koldioxidhalten 400 ppm för första gången på tre miljoner år. Därför satte den svenska regeringen, år 2017, upp målet att Sverige ska vara klimatneutralt år 2045. READ MORE
