| Summary: | Methods of experimental modeling of seismic impact on buildings and their models under force im-pacts, including the stability of building envelope systems, characters and basic parameters that correspond to loads occurring during real earthquakes are considered. The main methods of seismic impact on buildings and structures were analyzed using seismic platforms of software control, directed powerful underground explosion and vibration machines. The advantage of the vibration method is proved, which allows relatively fast and easy and low-cost testing of both full-scale buildings and structures, as well as their models. Experimental installation and method of testing of buildings and their models for seismic impact, excited with the help of simultaneously acting several vibration machines, are presented. Oscillograms of superposition of the first ІІ-ІІІ vibration modes were obtained when testing a model of the frame of a 9-storey building. In order to assess the degree of accuracy of the proposed method of simulating seismic impact from an accelerogram of one earthquake, floor movements of a building model were determined theoretically and experimentally. The comparison of the results of theoretical and experimental studies showed that the discrepancy between them is on average 10-15%. |
