SIMULATION OF WIND EFFECTS ON HIGH-RISE BUILDINGS

Sergey Makhortykh

Abstract

The problems of meteorological (wind) loads modeling on high-rise structures are considered. Arising oscillations lead to technical risks and uncomfortable being in residential and office rooms of these buildings. Technogenic impacts from transport and construction work can also lead to the development of negative oscillatory processes in buildings. Models describing the reactions of the structures of a building to outer impacts transmitted through geophysical media are proposed. Using spectral methods, based on decomposing of the signal into orthogonal rows for analyzing the proposed models, allows us to obtain the solution, as well as to optimize the structure of the simulation results. The use of these methods for practical tasks of non-destructive remote control is based on the considerable sensitivity of the harmonics of the spectral expansions to the values of the estimated parameters. A clamped beam model was proposed as the initial mathematical model of the considered system (building). It allows us to make simple computational schemes for analyzing of the oscillations in the structure of a building exposed to wind and technogenic loads. Many results are obtained in analytical form. The model makes it possible to investigate the resonant structure of the oscillations and correctly adjust the dampers of unwanted building dynamic reactions to external influences. The results of the analysis allow us to draw general conclusions about the danger of the excited oscillations, as well as the need to use vibration dampers.
