  1. 16. BRIDGE EDGE BEAM : NON-LINEAR ANALYSIS OF REINFORCEDCONCRETE OVERHANG SLAB BY FINITEELEMENT METHOD

    University essay from KTH/Bro- och stålbyggnad

    Author : Saima Yaqoob; [2017]
    Keywords : Bridge edge beam system; edge beam; overhang slab; structural analysis; non-linear finite element modelling; shear force; bending moment; distribution width; failure mode.;

    Abstract : Bridge edge beam system is an increasing concern in Sweden. Because it is the mostvisible part of the structure which is subjected to harsh weather. The edge beamcontributes to the stiffness of overhang slab and helps to distribute the concentratedload. READ MORE

  3. 17. Material properties of concrete used in skewed concrete bridges

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Ahmad Saad; [2016]
    Keywords : crack; skew slab; RCC slabs; fracture process zone; uniaxial compression test; uniaxial tension test; Brazilian splitting tension test; modelling linear behavior of concrete; bridges.;

    Abstract : This thesis has discussed both properties and geometry of concrete slabs used in bridges. It gave understanding on behavior of concrete in both tension and compression zones and how crack propagates in specimens by presenting both theory of fracture and performing concrete tests like tension splitting, uniaxial compression and uniaxial tension tests.

  4. 18. Cracking Assessment of Concrete Slab Frame Bridges Exposed to Thermally Induced Restraint Forces

    University essay from KTH/Betongbyggnad

    Author : Jonatan Ledin; Christensen Oskar; [2015]
    Keywords : Concrete slab frame bridges; Restraint forces; Thermal actions; Non linear FE analysis;

    Abstract : The usage of linear 3D FEA is widespread within the bridge design community, and although this tool provides substantial benefits in the design process, there are certain practical issues related to the application of this analysis tool. A situation in which such an issue prevails is when linear 3D FEA is used to analyze restraint forces due to thermal shrinkage or expansion in concrete slab frame bridges. READ MORE

  5. 19. Redistribution of bending moments in concrete slabs in the SLS

    University essay from KTH/Bro- och stålbyggnad

    Author : Einar Óskarsson; [2014]
    Keywords : Finite element analysis; reinforced concrete; concrete slab; non-linear analysis; crack control; fracture energy;

    Abstract : The finite element method (FEM) is commonly used to design the reinforcement in concrete slabs. In order to simplify the analysis and to be able to utilize the superposition principle for evaluating the effect of load combinations, a linear analysis is generally adopted although concrete slabs normally have a pronounced non-linear response.

  6. 20. The Birimian event in the Baoulé Mossi domain (West African Craton) : regional and global context

    University essay from Lunds universitet/Geologiska institutionen

    Author : Mikael Grenholm; [2014]
    Keywords : accretionary orogen; Atlantica; Birimian event; supercontinent cycle; Lomagundi-Jatuli event; Earth and Environmental Sciences;

    Abstract : The crystalline basement of the West African Craton (WAC) was established during the Siderian to Orosirian (circa 2.35-1.95 Ga) Birimian event through accretion of extensive tracts of juvenile crust that was tectonically juxtaposed with Archean cratons. READ MORE
