  1. 11. Lateral Stabilization of CLT Buildings - Modelling approaches

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

    Author : Lina Holmqvist; Sanna Källman Gleisner; [2022]
    Keywords : Technology and Engineering;

    Abstract : Cross-laminated timber (CLT) is an environmentally positive building material with high stiffness and load-bearing capacity. In combination with a low self-weight, CLT is a beneficial material to use for the load-bearing structure of high-rise buildings. READ MORE

  3. 12. Back analysis of rock mass properties in the regional fault zone under Lake Mälaren

    University essay from KTH/Jord- och bergmekanik

    Author : Jiaqi Liu; [2022]
    Keywords : Rock mass property; back analysis; tunnel deformation; optimization algorithm; numerical analysis; Bergmassans egenskaper; bakåtanalys; tunnleldeformation; optimeringingsalgoritm; numeriska analyser.;

    Abstract : The properties of the surrounding rock mass in underground projects have significant impacts on the design and construction. However, it is quite challenging to evaluate rock mass properties due to the great uncertainties of the geological conditions. READ MORE

  4. 13. Optimization of support in rock pillars between two parallel tunnels

    University essay from KTH/Jord- och bergmekanik

    Author : Alexander Kote; Sohaib Ishaq; [2022]
    Keywords : tunnel; rock pillar support; rock pillar stability; rock mass; stresses; arching effect; Nyckelord: tunnel; bergförstärkning; bergpelare; bergmassa; spänningar; valveffekt;

    Abstract : When two parallel tunnels are excavated under high to moderate horizontal in-situ stresses combined with minor deformations in the pillar between the tunnels, the in-situ stresses can be redistributed over the tunnels in form of two compressive arches and are transferred from the roof to the abutments of the two tunnels. At additional deformations in the pillar, a new redistribution of the stresses can occur creating one compressive arch over both of the tunnels. READ MORE

  5. 14. Optimal dead space in axial-type expander

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Martin Karman; [2022]
    Keywords : Dead space; Expander; Steam engine; Tolerance analysis; Axial-kolvmotor; Effektivitet; Expansionskammare; Kolv; Ångmotor;

    Abstract : In this thesis a method for determining optimal dead space in an axial-type expander is developed. The axial-type expander in question is for use in a steam engine, a environmental friendly and fuel-agnostic alternative to the ICE-engine. READ MORE

  6. 15. Timber pile-supported road embankment : Numerical and analytical analysis of field monitoring project E4 Råneå

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Kent Nystedt; [2022]
    Keywords : Geosynthetic reinforcement; Geosynthetic reinforced pile supported embankment; Pile distance; Embankment height; Finite element method; Pile efficacy;

    Abstract : The previous E4 Råneå road embankment was prone to flooding. Risk of flooding in combination with settlements of the road due to the weak underlying sulphide soil was problematic. The Swedish Transportation Administration improved the length section E4 Råneå by rebuilding the road using the method light embankment piling. READ MORE
