The aim of the assessment is to determine the influence of changes in summer and winter climatic temperatures and the influence of shrinkage on the behaviour of a reinforced concrete ramp with a total length of 54.6 m, width of 22.5 m, wall height of 3.5 – 7.785 m and ramp elevation of 4.1 m, which serves to service underground garages and supply the Multifunctional Sports and Cultural Pavilion in Brno. The aim of the assessment was mainly to determine the nature of possible failures – the formation and development of crack width; verify the behaviour of the reinforced concrete ramp on the effects of climatic temperatures, including insolation (absorption of solar radiation as thermal stress into concrete surfaces) and build a 3D model of the ramp in the ATENA software, including built-in reinforcement in the form of discrete bars.
