The chapter deals with an application of neural networks to the analysis of vibrations of medium-height prefabricated buildings with load-bearing walls subjected to paraseismic excitations. Neural network technique was used for identification of dynamic properties of actual buildings, simulation of building responses to paraseismic excitations as well as for the analysis of response spectra. Mining tremors in strip mines and in the most seismically active mining regions in Poland with underground exploitation were the sources of these vibrations. On the basis of the experimental data obtained from the measurements of kinematic excitations and dynamic building responses of actual structures the training and testing patterns were formulated. It was stated that the application of neural networks enables us to predict the results with accuracy quite satisfactory for engineering practice. The results presented in this chapter lead to a conclusion that the neural technique gives new prospects of efficient analysis of structural dynamics problems related to paraseismic excitations.

The Impact

Abstract Mining-related seismicity is a significant problem in regions with the exploitation in underground mines. Despite the fact that mining tremors result from human activity and are classified as so-called paraseismic shocks, as with earthquakes, they are random events. Moreover, these rockbursts could cause significant damage to surface structures, including buildings. This paper deals with the analysis of experimentally obtained results in terms of the differences between the mine-induced vibrations described by the response spectra from the free-field near a given building and the simultaneously recorded vibrations in the building foundations. The influences of epicentral distance, mining tremor energy and the value of peak ground acceleration on the curves of free-field—foundation response spectra ratio were studied. The impact of the type of building on the transmission of response spectra from the free-field vibrations to the building foundations was also analysed for three types of apartment buildings (low-rise, medium-rise, high-rise). The usefulness of the approximate models of the phenomenon of soil-structure interaction during earthquakes proposed in the literature is also estimated in this paper in specific instances of mining tremors. Furthermore, the study presents original, simple, empirical models for the evaluation of the differences in the response spectra originating from free-field and building foundation vibrations in the mining region.

New Buildings

Surface vibrations induced by mining rockbursts resulting from underground exploitation in the mines in western Poland were analyzed and classified into three different categories. Comparison of the accelerograms simultaneously recorded on the ground and on the foundations of typical buildings, as well as the response spectra determined on the basis of these records, leads to the conclusion that ground vibration characteristics have a significant influence on the nature of vibration transmission from the ground to the building foundation. Analysis of the response spectra, separately determined from both ground vibrations and building foundation vibrations, indicates that the standard response spectrum based on building foundation vibrations is more useful in the design of new buildings in areas of mining tremors than the spectrum based on ground vibrations. Moreover, the usefulness of the models of soil-structure interaction based on seismic data in California was investigated with respect to mine-induced rockbursts in Poland.
