  1. 1. Linear and non-linear FE-analysis of cracking behavior of wing walls in integral bridges

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

    Author : Andreas Ekman; Christoffer Sandin; [2018]
    Keywords : Non linear FE-modelling; Concrete Damage Plasticity; Wing wall; Crack propagation; Serviceability Limit State; Slab Frame Bridge; Technology and Engineering;

    Abstract : Wing walls on slab frame integral bridges has traditionally been designed for mainly earth pressure and its self-weight. It has also been designed separately from the rest of the bridge. Traditionally no 3D effects have been considered in the design of the wing walls. READ MORE

  2. 2. Comparison of ballasted and ballastless bridges for high speed trains

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

    Author : David Matos Sánchez; Maša Nikolic; [2016]
    Keywords : High-speed train; concrete bridge; beam bridge; dynamic; 3D dynamic;

    Abstract : The purpose of the project is to investigate the difference in performance betweenballasted and ballastless railway bridges dedicated to high speed trains by taking intoaccount both static and dynamic requirements. The main questions are:a) whether choosing a ballastless bridge results in a more slender section due tothe lower self-weightb) if the design of bridges for high speed trains is governed by the static or by thedynamic requirements.

  3. 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
