WebJun 1, 2000 · The issue of the difference between the design ground motion value and the value associated with any of the earthquake scenarios is addressed. A scaling factor, called the “ calibration factor for conditional mean ”, is introduced to deal with this, which simply represents the number of standard deviations by which the two values differ. WebSome hypotheses are necessary for developing conditional hazard maps: (i) availability of ground motion prediction equations (GMPEs) for both IMs, (ii) availability of magnitude and distance hazard disaggregation distributions for the primary parameter, (iii) the joint normality1of the chosen IMs, and (iv) availability of their correlation …
