  1. 16. Experimental analysis of limitations in the strut-and-tie method

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

    Author : Mikael Wahlgren; Niels Bailleul; [2016]
    Keywords : Strut-and-Tie method; Reinforced concrete; Concrete Damaged Plasticity; Fracture energy; Technology and Engineering;

    Abstract : One of the overall main purposes for a structural engineer is to design structures and structural elements so that they meet society’s safety requirements, yet use as little material as possible. In order to do so, the designer has to understand and simplify a complex reality. READ MORE

  2. 17. Shear cracks in reinforced concrete in serviceability limit state

    University essay from KTH/Betongbyggnad

    Author : Alexander Chemlali; Rickard Norberg; [2015]
    Keywords : Shear cracks; Serviceability limit state; Modified compression field theory; Reinforced concrete panels; Non-linear FE analysis; Wing wall; Skjuvsprickor; Bruksgränstillstånd; Modifierad tryckfältsteori; Armerade betongpaneler; Icke linjär FE-analys; Vingmur;

    Abstract : Shear cracks are formed when high oblique tensile stresses, e.g. in thin webs, exceed the tensile strength. A known example of this phenomenon is the extensive shear cracks that were found on the box-girder bridges Gröndal and Alvik, which were mainly caused by insufficient amount of shear reinforcement.

  3. 18. Influence of the ballast on the dynamic properties of a truss railway bridge

    University essay from KTH/Bro- och stålbyggnad

    Author : Lucie Bornet; [2013]
    Keywords : Ballast; Railway bridges; Experimental dynamics; Finite element modelling; Natural frequencies; Eigenmodes; Bridge stiffness.;

    Abstract : To deal with a rapid development of high-speed trains and high-speed railways, constant improvement of the railway infrastructure is necessary and engineers are continuously facing challenges in order to design efficient and optimized structures. Nowadays, more and more railway bridges are built and thus, they require the engineers’ attention both regarding their design and their maintenance. READ MORE

  4. 19. Glued laminated timber space truss systems

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Nicola Moggio; [2012]
    Keywords : Technology and Engineering;

    Abstract : Space structures are a leaf taken from Nature. Natural forms possess exceptional rigidity and use minimum materials to maximum structural advantage. To quote Makowski, "Natural forms act in the direction of minimum effort". Man has not been slow in copying these examples drawn from Nature. READ MORE

  5. 20. The mechanical properties of lattice truss tructures with loadbearing shells made of selectively laser melted Hastelloy X (TM)

    University essay from KTH/Industriell produktion

    Author : Jonas Saarimäki; [2011]
    Keywords : Selective laser melting; SLM; lattice truss structure; lattice; tensile testing; compression testing; bend testing; superalloy.;

    Abstract : This thesis discusses how to test the mechanical properties of openlattice truss structures and hybrids being a tube containing a latticetruss structure. By properties we mean strength, stiffness, thermalconductivity and so forth. READ MORE
