  1. 11. Probabilistic non-linear finite element analysis of concrete buttress dams

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

    Author : Adrian Ulfberg; [2019]
    Keywords : ATENA; FREET; SARA; probabilistic; numerical; Kalhovd; FEA; FEM;

    Abstract : Assessment of concrete buttress dams today consists of using analytical methods to investigate the stability in different failure modes. However, they simplify the problem at hand and neglect certain important features linked to geometry and thus not truthfully appraise the structures real stability. READ MORE

  3. 12. WIND TURBINE FOUNDATIONS IN CLAY : Technical and economic considerations for proposals for wind turbine foundations

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Michail Papagiannis; [2018]
    Keywords : clay; wind turbine; bored pile; monopilem; soil stratigraphy; seismic loads; DIN; Eurocode;

    Abstract : This thesis approaches the problem of the cost-efficient wind turbine foundation on an onshore site of clayey soil characteristics. The given soil stratigraphy includes a layer of clay and two sands of different density. The characteristics of the soil and the water level that were used as input come from a site in Peloponissos, Greece. READ MORE

  4. 13. Contingent Convertible Bonds. A Market-Conform Equity Derivative Model

    University essay from Göteborgs universitet/Graduate School

    Author : Giulia Cesaroni; [2017-07-25]
    Keywords : Contingent Convertible Bonds; CoCos; TIER 2; Additional TIER 1; Equity Derivative Model; Bates Model; Stochastic Volatility; Implied Volatility; Jump Diffusion Process; Monte Carlo Simulation; Quadratic Exponential Scheme;

    Abstract : This thesis focuses on the pricing of the Contingent Convertible Bonds (CoCos), using the Equity Derivative approach and the Bates model to simulate the stock price with Monte Carlo algorithm. The CoCo bonds are hybrid financial instruments with loss-absorbency features, characterized by a conversion into equity or a write-down of the face value, when a specified trigger event happens, which is usually related to an accounting indicator of the bank.

  5. 14. Analysis of Tripod shaped high rise building using Tubed Mega Frame structures

    University essay from KTH/Betongbyggnad

    Author : Sujan Kumar Rimal; Levi Grennvall; [2017]
    Keywords : high-rise building; inclined; slanted; tubed mega frame; tripode; höghus; vinklad; lutande; tubed mega frame; trefot;

    Abstract : Most of the tall buildings that are built today have a straight and vertical shape, because vertical buildings are more stable and easily built than slanted ones. In the case of vertical building, bending moments in the base only exists from horizontal loads such as wind and seismic loads, but in slanted buildings there will also be bending moments from dead and live loads.

  6. 15. Non-linear Wave Impact on Monopile Structures

    University essay from KTH/Lättkonstruktioner

    Author : Philipp Schöpfer; [2016]
    Keywords : ;

    Abstract : This Master Thesis deals with non-linear wave impacts on monopile structures by introducing a potential flow solver named OceanWave3D (OCW3D) for simulating free surface waves and their kinematics under engineering consideration. A comparison to Rambøll’s analytical tool WAVGEN is conducted with the aim of providing distinct recommendations on the application and suitability of both programs for the monopile design. READ MORE
