Abstract
Nowadays there is a tendency for the requirement toughening when the construction projects are designed. The existing standard and rule control in terms of the identification of the external load on buildings and constructions is directly connected with the reliability and safety control of building constructions, and one of the most important parts of the design is to take into account the wind effect. Air flows have a different impact on buildings due to their height; it is connected with the surface air existence. Consequently, the wind effect on the high-rise should be well-researched. The acting normative documents (SP 20.13330.2011 “Loads and impacts”) formalize the inclusion of a special evaluation study of the wind conditions and aerodynamic property in the list of project documentation for the reliability and safety control of the high-rise building constructions. The identification of the wind conditions and aerodynamic property is available only in accordance with the theoretical and experimental analysis, of which a procedure is described in the present article.
Highlights
The development and progression of engineering of the construction provide a means of the new off-standard space planning decision creation and improve the activity of designers and architects
According to the received data, it is possible to calculate the average values of the pressure shape factor for different angles of wind attack, from 0° to 360°, using formula (1)
Due to the obtained results, it can be asserted that the average values of the pressure shape factor are approximately in the range ± 1,5
Summary
The development and progression of engineering of the construction provide a means of the new off-standard space planning decision creation and improve the activity of designers and architects. The high-rise building is not exception: today in most major cities of the world construction of skyscrapers is first ranks in the entire construction complex [1]. Despite the technological progress and the opportunity to create the unique structures, the main problem of architects and engineers, while developing the design documentation, is the procuring control of reliability and safety of constructions. First of all, this requirement applies to the high-rise, because high-rise buildings belong to the class of increased danger. Based on experience, which gained of the monitoring of high-rise buildings, it was made a conclusion of the necessity of wind effect [2]. The building itself is adversely affected by the alternate wind load, which cause deformation of the high-rise building and destruction
