چکیده مقاله:
The amplitudes of seismic wave might amplify significantly as it propagates through the soil layers near the ground surface during an earthquake. Analysis of site amplification potential is strongly influenced by the uncertainty associated to the definition of soil thickness and their properties. In this paper, the jointlydistributed random variables method for stochastic analysis of site amplification is used. The selected stochastic parameters are shear wave velocity and the soil thickness. The circular frequency is regarded as a constant parameter. The base is considered as a rigid rock and no damping is assumed for soil layer. Theresults are compared with those of Monte Carlo simulation. Comparison of the results indicates good performance of the proposed approach for stochastic analysis of site amplification potential. Sensitivity and parametric analyses are conducted to verify the results
