The study of wind effects on the bridge constructions

Abstract

Construction of bridge structures occupies one of the leading positions in the construction industry. However, the design of these objects is a complex multi-factor task. Particular attention in the development of bridge structures must be paid to wind loads, since their dynamic loads can cause a number of adverse aeroelastic reactions. Large-scale bridge structures, which are flexible structures, are more susceptible to horizontal influence of the wind. This article presents a description of the study of wind impact on a bridge being built in the city of Moscow, according to a technique that was developed by employees of the UNPL AAISK (NRU MGSU). In this case, a test of the span section of the model on a specialized stand was conducted. The example of this object shows a graph of the dependence of the amplitude of oscillations of the bridge span on the wind speed without the use of fairings and their installation. According to the results of the work conclusions.
