SUMMARY:

Most physical phenomena cannot be predicted with complete certainty and repeated measurements of these phenomena generate random results, with some of these results being more frequent than others. Reliability analyzes are commonly used to examine the behavior of structures subjected to such phenomena. In this sense, the present work presents reliability analyzes to evaluate the behavior of wind effects of the CAARC (Commonwealth Advisory Aeronautical Research Council) standard tall building model through the beta index. The standard tall building model was studied in different positions, subjected to variable wind actions, in isolation and with the existence of different neighborhoods. Probabilistic concepts and histograms were presented and discussed in relation to the directions adopted by CAARC, for reliability indices. With the preliminary results found, it was observed that the existence of a neighborhood affects the average values and reliability indices, both increasing and decreasing compared to the isolated building, depending on the situation. Therefore, this study presents interpretations and levels of reliability that can help predict the behavior of tall buildings subjected to wind actions in the presence of neighborhoods.
