Experimental-Analytical Method of Data Processing during Wind Loading to Determine the Behavior of High-Rise Buildings under Seismic Load

摘要

In recent years, high-rise constructions are intensively built in seismically active areas worldwide (US, Canada, Japan, Chili, Europe, etc.) accompanied by the development of the respective regulatory framework. According to the authoritative experts, it is not appropriate for high-rise buildings to use current regulatory requirements based on the summarized experience of the seismic behavior of low-rise buildings during seismic loading. The principles of seismic safety of high-rise buildings have not been conclusively formulated yet For that it is necessary to make new building regulations. Consquently there is a big experimental testing ground over a vast territory of the world and high-rise buildings constructed there wait for experimental testing during real earthquakes. The necessity of testing of the seismic stability of high-rise buildings experimentally without awaiting for testing by real earthquake comes to the fore in the described situation. In the paper, the method that allows to estimate actual technical parameters of a building using experimental data of a building during wind loading, damping decrement, resonant frequencies, building behavior during any seismic wave passing through its foundation, is described.
