Abstract

Andersen’s chart (Andersen & Berre, 1999) is a graphical method of observing cyclic soil response. It allows observing soil response to various stress amplitudes that can lead to liquefaction, excess plastic deformation or stabilizing soil response. The process of obtaining the original chart has been improved, and the new method is described in this paper. Algorithm based approximation is introduced; it replaces handmade lines with computer generated curves. This makes the obtained estimates more reliable and once implemented the procedure is faster than the original method.
