New procedure for assessing the seismic hazard and behavior of soft and stiff grounds caused by the multifactor seismic effect

This paper deals with the studies for determining the degree of seismic hazard of grounds by taking into account all possible most important factors that influence their seismic hazard degree. The procedure, which is developed by the author on the basis of new approaches to solve this problem multilaterally, is presented. The characteristics of the behavior and quantitative estimate of seismic intensity amplification of soft and stiff grounds under seismic effects are shown.
