The paper deals with the analysis of the soil-structure interaction in case of the transmission of ground vibrations from mining tremors to medium-height building foundation. The one of parameters used in scales of mine-induced dynamic influences (GSI-2004) to evaluate the harmfulness of ground vibrations to surface structures - maximal values (amplitudes) of resultant acceleration of horizontal vibrations...
The paper deals with the evaluation of the natural frequencies of vibrations of the modified typical medium-height load-bearing walls modeled as the reinforced concrete thin plates. The small and the large changes of the wall stiffness and mass resulted from the new door-ways size and position were discussed. The Combined Approximations (CA) hybrid method was used as an effective reanalysis approach...
The paper deals with an application of neural networks for evaluation of soil-structure interaction in case of the transmission of ground vibrations from mining tremors to building basement. The problem of is analyzed with respect to typical prefabricated eleven-storey building with load bearing walls. The comparison of maximal values (amplitudes) of vibrations (accelerations) rccorded at the same...
The paper deals with an application of the principal component analysis and neural networks to computation of fundamental natural periods of prefabricated medium-height buildings. The analysis is based on long-term tests performed on actual structures. The identification problem is formulated as the relation between structural and soil basement parameters, and the fundamenta! period. Back-propagation...
Underground coal and copper are exploitation in two Polish mining regions causes mining tremors. The main problem discussed in the paper was formulated as the neural network evaluation of a relation between mining tremor energies, epicentral distances and acceleration response spectra. Neurally evaluated spectra were compared with spectra computed on the basis of experimental data. The main advantage...
