The remarkable design and construction of constructions in large cities of optimization of engineering methods have as structural models in the increasingly high structural structures and/or stimuli, with low resistance and damping, transforming them into high structures in the increasingly structural structures. Powered by the action of the wind. Thus, it becomes rigorously necessary to study the possible constructions of the buildings in question, mainly as dynamic actions in the most realistic way as their non-deterministic properties. Furthermore, it is important to highlight, no less importantly, the study of the way of individual interaction, considering its influence on the resistance of the (global) structural system. Therefore, the conduct aims to analyze the present with wind action insurance contracts based on human comfort criteria. For the study in question, two “tall” buildings were considered, including the mixed structures (steel-concrete) and the other reinforced concrete structures. The first has a total height of 173 m with 48 floors, with a maximum dimension in the plan of 45 x 32 m. The second has a total height of 140 m with 40 floors, with a maximum dimension in the plan of 9 x 29 m. With the results obtained, it was noticed the reduction of the modelling process, as it significantly increased the reduction of the natural frequencies of the soil interactions of the buildings and accelerations, as it favored the increase of the reduction of the natural frequencies of the interactions of the buildings and the longitudinal buildings and transversal buildings.
