  1. 1. Dynamic Analysis of Portal Frame Bridges for High-Speed Trains : A Parametric Study

    University essay from KTH/Bro- och stålbyggnad

    Author : Antonio Dib; Ramayana Salgado; [2023]
    Keywords : ;

    Abstract : A high-speed railway network is important for Sweden’s development. However, anincreasing train speed brings new challenges in bridge design due to higher bridgeaccelerations. READ MORE

  3. 2. Recycling of concrete waste with wood waste through heating compaction

    University essay from KTH/Betongbyggnad

    Author : Li Liang; [2020]
    Keywords : Recycling; Concrete waste; Wooden waste; Heating powder compaction;

    Abstract : Concrete, as primary building material, is widely used in most construction project. For this reason, large amounts of concrete waste were generated from construction and demolition. One way to reuse concrete waste is to use it as backfill material for landfilling and road bases. READ MORE

  4. 3. Indirect methods as quality control of cemented hydraulic fill : Renström mine, Boliden mineral AB

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Amanda Rask; [2019]
    Keywords : Backfill; CHF;

    Abstract : The Renström mine, Boliden Mineral AB, uses, among other methods, the Transverse long hole stoping method with backfill. The mine uses a cement-stabilized hydraulic fill (CHF), which is a mixture of enrichment sand, cement and water. The most important factor in relation to strength is the water cement ratio.

  5. 4. Finite Element Analysis of the Dynamic Effect of Soil-Structure Interaction of Portal Frame Bridges - A Parametric Study

    University essay from KTH/Bro- och stålbyggnad

    Author : Turgay Dagdelen; Shaho Ruhani; [2018]
    Keywords : Soil-Structure Interaction; Railway Bridge; Portal Frame Bridge; Dynamic Analysis; Parametric Study; Nonlinear Analysis; Jord-struktur interaktion; Järnvägsbro; Plattrambro; Dynamisk analys; Parametrisk studie; Icke-linjär analys;

    Abstract : In Sweden, the railway sector currently faces the challenge of developing its first high-speed railway line, in response to the need to provide faster domestic and international transport alternatives. High-speed train passages on railway bridges can cause resonance in the bridge superstructure, which induce high accelerations that should not exceed the limits stipulated in the current design code.

  6. 5. Dynamic Soil-Structure Interaction of a Portal Frame Railway Bridge - Numerical Analysis on a Case Study Bridge

    University essay from KTH/Bro- och stålbyggnad

    Author : Rita Ikzer; [2018]
    Keywords : Dynamic Analysis; Soil-Structure Interaction; Damping; Railway Bridge; Portal Frame Bridge; Full FE-Modeling; Simplified Modeling; Dynamisk analys; Jord-struktur interaktion; Dämpning; Järnvägsbro; Plattrambro; Detaljerad FE-modellering; Förenklad modellering;

    Abstract : In the field of structural dynamics, a broader knowledge about relevant phenomena that affect the dynamic behavior of railway bridges is vital for structural engineers and design code administrators. The knowledge might benefit in an increased understanding of e.g. the resonance phenomena, and in improvements of the existing design codes. READ MORE
