Abstract


There was made a comparison of the experimental results, which were made on the basis of rolled metal thin-sheet profiles arch's full-size shift under the wind load influence on the one hand, and computer modeling results by the method, which was described in the article of Veselev, Yurii and Karabutov, Michael Reduction of rolled U-shaped profiles with reduced rigid features to an even T-shaped profile. Measurement of the arch'points shift was made in the quarter and in the middle of the arch's angular opening with the wind speed of 9 m/c. The arch modeling was based on the Solid Works software package as well as the modeling of wind flow by means of the virtual aerodynamic tunnel's construction was based on the COSMOSFloWorks software package. The methodological basis of the research are the Navier-Stokes equation and the equation of the condition of the fluid medium's components. The results are the estimation and comparison of the maximal arch shifts under experiment and computer modeling as well as the substantiation of all results.
