| Abstract [eng] |
The aim of master’s thesis is to analyze wind influence on tall, atypical shape buildings and to find the wind pressure coefficients of an atypical building. The work consists of three main parts: literature review, digital wind tunnel research methodology, results and discussion. The first part presents the basic knowledge about wind effects on tall buildings, three main effects of wind on high-rise buildings are analyzed and possible variants of dynamic simulations to assess wind influence are reviewed. Also, by analyzing the aerodynamic properties of various forms of buildings studied in scientific publications, possible modifications of buildings that reduce the impact of wind are presented. In the second part of master’s thesis digital wind tunnel research methodology is presented. This methodology specifies how the digital wind tunnel test will be performed, the parameters required to perform it and the formulas used in the calculations. In this work numerical research methods are applied and experimental data from a standard high-rise building is taken from the work of other scientists. These experimental data are compared with the obtained results of the digital wind tunnel, proving the accuracy of the calculation program. Finally, a digital wind tunnel test for a twisted-shaped building is presented and the pressure coefficients on the building surfaces are obtained. In the third part the results of study and their discussion is presented. The pressure coefficients are graphically compared for a standard tall building and a twisted building. |
