    • Finite element modelling and parametric studies of semi-closed thin-walled steel polygonal columns 

      Author: Ryan Bona; Supervisor: Koltsakis Efthymios; Opponent: Manoleas Panagiotis
      (České vysoké učení technické v Praze. Vypočetní a informační centrum.Czech Technical University in Prague. Computing and Information Centre., 2017-01-08)
      Objective of this work is to study the proposed structural sections in design situation and to investigate possible design models. The expected structural behavior of the column is a mixture between the open and closed ...

    • Resistance of Polygonal Cross sections of Lattice Wind Tower 

      Author: Jia Bicen; Supervisor: Koltsakis Efthymios; Opponent: Manoleas Panagiotis
      (České vysoké učení technické v Praze. Vypočetní a informační centrum.Czech Technical University in Prague. Computing and Information Centre., 2017-01-08)
      This thesis represents the parametric study of polygonal cross section of lattice tower. It consists of the numerical analysis based on finite element method (ABAQUS) and analysis based on EN 1993-1-3. The objective of ...

    • Stiffness over the mid-support for a modified single overlap joint of a single bay trapezoidal steel sheet profile used in long spans 

      Author: Cardenas Perez Jesus Abraham; Supervisor: Iqbal Naveed; Opponent: Koltsakis Efthymios
      (České vysoké učení technické v Praze. Vypočetní a informační centrum.Czech Technical University in Prague. Computing and Information Centre., 2017-01-08)
      The goal of this research is to test and analyze the current single overlap connection in order to get the spring stiffness acting there and see if improvements can be made. Theoretical analysis, Finite Element Modelling ...
