Experimental determination of the combined aerodynamic characteristics of building and structure models
Abstract: The article is about the procedure of determining the aerodynamic characteristics of solid-wall and frame structures in the DonNACEA wind tunnel. For this purpose there have been developed and designed a three-component aerodynamic balance and an instrument panel which make it possible to evaluate the response of the structures along and perpendicular to the wind flow and an aerodynamic moment. In the aggregate it allows carrying out the dummy test of any complexity for buildings and structures varying ion the aerodynamic form. The developed system of determining the combined aerodynamic characteristics of building and structure models guarantees accuracy sufficient for the engineering practice at the minimum timetable to prepare the initial data and to analyze the observations. A continuous journalizing of the testing results in the digital format makes a further analysis easier with the help of different systems of the statistic and regression analysis.
Keywords: wind tunnel, wind, aerodynamic balance, head resistance, lifting force, aerodynamic moment, dummy test.
