How to Estimate Characteristic Value for Design
Seminar Conducted by Prof KK Phoon.
The purpose of this lecture is to take the audience through three key concepts so that the characteristic value can be estimated in a more consistent way: (1) Statistics – effect of the coefficient of variation on the 5% fractile of a soil property measured at a point, (2) Spatial variability – effect of the scale of fluctuation on the 5% fractile of a spatial average defined over a zone of ground governing the behaviour of a geotechnical structure at a limit state [refer to Clause 184.108.40.206(9)], and (3) Mechanics – effect of failure mechanism at a limit state on the 5% fractile of a mobilized strength. Some examples are provided. No prior knowledge of statistics or probability needed.
