Site Response Analysis for Vertical Ground Motion
Abstract eng: This study initially considers a uniform soil layer subjected to vertically propagating harmonic P-waves. The response of the layer is calculated analytically, considering onedimensional propagation, and numerically employing time domain coupled consolidation Finite Element analysis for a range of input frequencies. The computed amplification function is shown to significantly depend on the modelling of the fluid phase and the soil permeability. Subsequently, a ground profile corresponding to a downhole array in Dahan (Taiwan) is examined assuming undrained, drained and coupled consolidation behaviour. The numerical predictions are compared with the vertical recorded response during the 1999 Chi-Chi earthquake demonstrating a very good agreement for the coupled consolidation analysis and highlighting the limitations of the other two approaches (i.e. drained and undrained analyses).
