Soils' seismic property research on the basis of investigation of their nonlinear properties

Abstract

Abstract. The most important problem of seismic microzonation (SMZ) is to prove the assessment of soil conditions' influence on the response of buildings and constructions. On the modern stage, SMZ can not remain in "linear" positions, and empirical tools of SMZ take into account nonlinear soil properties. A number of instrumental techniques for nonlinear phenomenon investigation in soils are given in the paper. New parameters describing nonlinearity are introduced and their practical usage efficiency is shown.
