This graduation paper presents the selection of a vertical support structure for the light construction, 105 m in height, positioned at a height of 0 m above sea level. The criterium for designing the light construction is mass, whereby conditions for load-bearing capacity and stability, must be met satisfied. The analyzed vertical support structure, with its technical solution, will meet the aforementioned criteria, as well as the load-bearing capacity of the glass cover. Additionally, to meet the criterion of lighter weight, two materials were analyzed: steel and aluminum alloy. The vertical supports produced by Schuco and Jansen are compared in this paper. The Schuco FW50+ series supports are made of aluminum alloy, while the Jansen series supports are made of steel. The graduation paper presents calculations for variable and constant loading, dimensioning and the selection of the vertical support structure. Due to increasingly stringent requirements for environmental protection, energy efficiency and design that play an increasingly important role in the final product's appearance, it is necessary to produce a structure that meets all the specified conditions. The above mentioned structure is compared in terms of weight as well as other criteria such as performance, installation, thermal insulation and price.
