Limitation of inbuilt shear modulus correlation in the SHAKE2000 was highlighted by Anbazhagan et al2,3. Of available 18 shear modulus correlations, correlation given WebIn addition to the following, it should be noted that exceptions to typical values of soil properties occur often. All foundations must have a factor of safety applied for design purposes (typically between 2 and 4). Foundations typically need to be taken down to a depth where seasonal changes and plant life will not affect the soil properties.
