  1. 1. Theoretical study of anisotropic effects in crystal growth on the example of concrete and calcium oxalate monohydrate

    University essay from Lunds universitet/Kemiska institutionen

    Author : Vilhelm Ekberg; [2019]
    Keywords : anisotropic crystal growth; COM; C-S-H; PM6; ReaxFF$_{ textrm{SiO}}$; organizing molecular matter; nanochemistry; nanokemi; Chemistry;

    Abstract : While many crystals, both natural and artificial, grow isotropically, there are examples of crystals growing anisotropically. The aim of this theoretical study was to confirm the growth modes displayed by three different crystals, representing 3D, 2D and 1D structures. READ MORE

  3. 2. Är ekologiskt hållbar arkitektur och stadsplanering ekologiskt hållbar? : vertikal skog i förhållande till ekologisk hållbarhet

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Sofie Sjöstedt; [2018]
    Keywords : ekologisk hållbarhet; hållbar utveckling; urbanisering; vertikal skog; gröna tak; omställning; humanekologi;

    Abstract : Att planera och bygga hållbara städer och miljöer för framtiden diskuteras febrilt till följd av urbanisering, befolkningsökning och klimatförändringar. Integrerad grönska på fasader och tak är ett vanligt hållbarhetsverktyg att använda för att göra den täta staden grönare och genera ekosystemtjänster. READ MORE

  4. 3. Numerical Modelling and Sensitivity Analysis of Tunnel Deformations in London Clay

    University essay from KTH/Jord- och bergmekanik

    Author : Malin Sandström; [2016]
    Keywords : Small-strain stiffness; Mohr-Coulomb; Plaxis; sensitivity analysis; tunnels; London Clay;

    Abstract : In dense cities, the interactions between all structures, from tall skyscrapers to complex underground tunnel systems, need to be carefully analysed as soon as a new project is considered. This is necessary because of the stress changes in the soil induced by each new construction. READ MORE

  5. 4. Design of Perimeter Walls in Tubed Mega Frame Structures

    University essay from KTH/Betongbyggnad

    Author : Niklas Fall; Viktor Hammar; [2014]
    Keywords : Concrete; Skyscrapers; Perimeter Walls; Tubed Mega Frame; non-linear FE-analysis; Betong; Tvärväggar; Skyskrapor; TMF-konstruktioner; ickelinjär FE-analys;

    Abstract : The Tubed Mega Frame is a new concept for constructing high-rise buildings,based on the idea of moving the main bearing system to the perimeter of thebuilding by using a number of large hollow columns, mega tubes, connected byperimeter walls at certain levels. The concept is under development by Tyréns ABand has not yet been implemented in reality. READ MORE

  6. 5. Construction Methodology of Tubed Mega Frame Structures in High­ Rise Buildings

    University essay from KTH/Betongbyggnad

    Author : Tobias Dahlin; Magnus Yngvesson; [2014]
    Keywords : Tubed Mega Frame; self-compacting concrete; construction methodology; skyscrapers; advanced formwork systems; floor cycle; construction sequencing; time planning; Tubed Mega Frame; självkompakterande betong; byggmetodik; avancerade formsystem; våningscykel; sekvensering av byggnation;

    Abstract : As a response to the ever denser cities, skyscrapers have become yet more popular and are growing more and taller than ever. A new efficient structural system for skyscrapers has been proposed by Tyréns AB, called the Tubed Mega Frame. This structural system consists of hollow concrete tubes at the perimeter of the building. READ MORE
