Construction disasters caused by wind load assessment errors

This article discusses the nature of wind loads on building structures and the consequences of errors in assessing these loads, which may lead to structural failures. Various methods for determining aerodynamic actions are analyzed (normative models, wind tunnel tests and CFD simulations). Examples of failures caused by wind action are presented, emphasizing the importance of dynamic analysis in the design process. Conscious consideration of the dynamic wind influence is crucial for ensuring the durability and safety of building structures. Structural catastrophes are an ever-present element accompanying facilities, during both the construction and service life phases. The possibility of such phenomena occurring in both cases is equally high and may originate from random causes associated with natural forces (floods, seismic shocks). Nevertheless, human factors and related design errors must also be acknowledged. This article presents the characteristics of wind-induced actions, with particular attention to the essence of dynamic analysis. The methods for determining aerodynamic actions and discrepancies in the obtained results are also described.
