- Handbook Of Risk Assessment In Geotechnical Earthquake Engin
Geotechnical earthquake engineering is ripe with uncertainty primarily because of the inherent variability of geotechnical materials and the stochastic nature of earthquake ground motions. Capturing and translating uncertainty through any engineering analysis is necessary for resolving the mean or median response with any confidence, and for estimating the dispersion of possible results. Geotechnical earthquake engineering is a pseudo-empirical discipline where theory dictates the trends of the analytical models but data drives the shape, coefficients, and values of the numerical results. A model used in geotechnical earthquake engineering is only as good as its accuracy with respect to the empirical data. Uncertainty can be conceptually lumped into two groups; the inherent variability of the underlying phenomena, and uncertainty as a function of modelling, measuring, and other engineering machinations that are not part of the phenomena. These are termed aleatory and epistemic uncertainty respectively. These two groups of uncertainty can have a strong influence on the outcome of some engineering analysis and are often not easily separable. Recent advances in probabilistic methods have lead to improved uncertainty analysis in geotechnical earthquake engineering and related fields. This book describes a select (and by no means comprehensive) group of studies which the author feels demonstrates improvements in how uncertainty is quantified and propagated through the analysis thereby providing a broader understanding of the problem at hand and the desired outcome. The select group of studies is biased towards the author’s work but also draws on work from others that strive for the same goal of propagating uncertainty for improved understanding and accuracy. This book will be of immense help to all those contemplating to acquire an expert knowledge of earthquakes.
