FEATURES OF THE INFLUENCE OF AIR FLOWS ON HIGH-RISE BUILDINGS

Abstract

The article investigates problems related to the peculiarities of the effects of air flows on high-rise buildings. The relationship between the shape of the building and its aerodynamics is revealed. The impact of changing the shape of the building on the aeration regime is investigated. Wind impact is the main negative factor affecting high-rise buildings. Its influence is so great that only constructive measures to increase the size of load-bearing elements and the class of concrete will not solve the problem. Traditionally, it is believed that when designing objects with author's architecture, engineers and designers are secondary figures who only take the lead and fulfill any wishes and whims of the architect. When designing high-rise buildings, the wind interferes with these "traditional" relationships, placing such enormous loads on the building that the architect, designer, and customer sit down side by side and begin to communicate to reach a consensus. As a result, the top floors, which could accommodate luxury penthouses, are being used to house multi-ton pendulum dampers. The percentage of usable space is falling, as technical rooms occupy not the usual 1.5%, but all 10%. And even the shape of the building needs serious changes. Buildings, due to their length and angularity, belong to the category of "poorly streamlined objects", as a result, the environment actively fights this obstacle, trying to bend the building, twist it, overturn it, tear off or press in the facade panels, and, in addition, burn it with sunlight and create. Currently, the importance of considering wind loads is increasing due to the increase in the number of high-rise buildings being built in densely populated cities and their number of floors.
