ARCHITECTURAL-BUILDING AERODYNAMICS

This article gives a brief historical digression about the formation of architectural and building aerodynamics as a separate branch of the construction science. The main methods and approaches to the solution of problems of architectural and building aerodynamics are listed; the classification of problems of aerodynamics of structural steel according to the studied objects is given; main peculiarities of the research in selected areas are briefly indicated. The aim of the work is to systematize existing approaches to assessing wind impact on structural steel taking into account some modern international requirements, as well as to choose the optimal method for solving this problem in relation to various structural steel. It is established that, currently, the study about wind impact is especially important for high-rise buildings, structures, and structural steel nonresistant to dynamic loads (long span bridge conduits, gins polarized, thin-shell tubes, etc.), as well as for residential estates with restrained urban conditions. It is necessary to carry-out these aerodynamic studies at the designing stage for the above objects because it is directly related to the issues of reliability and safety.
