  1. 1. Design of Ultra High Performance Fibre Reinforced Concrete Bridges : A Comparative Study to Conventional Concrete Bridges

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

    Author : Viktor Eriksson; [2019]
    Keywords : Bridge design; CO2 emissions; Mechanical properties and behaviour; Straight short steel fibres; UHPC; UHPFRC; Bro dimensionering; CO2 utsläpp; Korta raka stålfibrer; Mekaniska egenskaper och beteende; UHPC; UHPFRC;

    Abstract : The use of Ultra High Performance Fibre Reinforced Concrete (UHPFRC) in the construction industry started in the 1990s and has since then been used for bridges all over the world. The mechanical properties and the dense matrix result in lower material usage and superior durability compared to conventional concrete, but the implementation of UHPFRC in the Swedish industry has been delayed.

  3. 2. Analysis of post-tensioned concrete box-girder bridges : A comparison of Incremental launching and Movable scaffolding system

    University essay from KTH/Bro- och stålbyggnad

    Author : Hamad El Hamad; Furkan Tanhan; [2018]
    Keywords : Movable scaffolding system; MSS; Incremental launching; post-tension; prestress; slen- derness; box-girder; Stockholm Bypass; Movable scaffolding system; MSS; Etappvis lansering; efterspänning; förspänning; slankhet; box-girder; Förbifart Stockholm;

    Abstract : When designing a bridge it is of high importance that the geometry for the cross section is optimized for the structure. This is partly due to the influence of the amount of material needed and its impact on the budget and environment. READ MORE

  4. 3. Reinforced Concrete Subjected To Restraint Forces : A comparison with non-linear numerical analyses

    University essay from KTH/Bro- och stålbyggnad

    Author : Niels Brattström; Oliver Hagman; [2017]
    Keywords : Restraint forces; concrete; cracking; restraint degree; crack width; creep; thermal actions; shrinkage; Tvångskrafter; betong; sprickor; inspänningsgrad; sprickvidder; krypning; termisk last; krympning;

    Abstract : In Sweden, it is Eurocode 2 which forms the basis for performing a design of concrete structures, in which methods can be found treating the subject of restrained concrete members and cracking in the serviceability limit state. In the code, both detailed hand calculations procedures as well as simplified methods are described. READ MORE

  5. 4. Industrial symbiosis Canvas business model between a recysling company, an energy company and a real estate manager

    University essay from KTH/Industriell ekologi

    Author : Emmeli Gravert; Jenny Mattsson; [2016]
    Keywords : Industrial symbiosis; Canvas business model; responsibility roles; implementation; energy and material flows; Industriell symbios; Canvas affärsmodell; ansvarsroller; implementering; energi- och materialflöden;

    Abstract : Industrial symbiosis involves cooperation by exchanges of resources between companies, and furthermore develops regional competitiveness and increase new business opportunities. To consider the definition of industrial symbiosis within a company, and allow innovations in circular economy and resource usage, creates opportunities for a company to grow businesses by reaching economic development and increased efficiency.

  6. 5. Dynamic Soil-structure Interaction of Portal Frame Bridge Walls for High-speed Railways

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

    Author : Henrik Malm; [2016]
    Keywords : SSI; Soil-structure interaction; Structural dynamics; High-speed railway bridges; Impedance; Receptance; Finite element method; Portal frame bridge; Technology and Engineering;

    Abstract : In Sweden, high-speed railways is a subject for public debate. The first stage of a high-speed train network, Ostlänken between Stockholm and Linköping, is under investigation, and is planned to be trafficked in 2028. The high-speed railway is intended to hold traffic with speeds up to 320 km/h. READ MORE
