Booth T. A. The effectiveness of the steel structures of console Ferris wheel, diameter of up to 30m.. — Manuscript. Thesis to obtain the scientific degree of Candidate of Technical Sciences in speciality 05.23.01 — Building Structures, Buildings and Constructions. Kyiv National University of Construction and Architecture, Kyiv, 2013. In the thesis deals with the efficient design of cantilever steel wheels review. The main principles of rational choice type lattice truss type with parallel chords in diameter wheels within 18-30m, taking into account changes in the design scheme in operation. The method of choice rational tower locations console Ferris wheel at constant values mark the center of rotation at the base of the towers depending on the distribution of stresses arising in this type of structures from external loads. Reduction of steel in construction is achieved by refinement of flange joints and overall impact on the evolution of numerical models redistribution of stresses in the elements of design. Determined the overall vitality of the static structures of exclusion from work elements bolted joints. The results of numerical calculations using reasonable ITU PC LYRA 10.4 and Autodesk Simulation Multiphysics 2013 based on geometric-constructive nonlinearity. Key words: Ferris wheel, bolted joints, flanges, finite element method, the stress-strain state, nonlinearity
