Abstract

Liquefaction phenomena may cause two major concerns: 1- Ground deformation or ground failure due to the excess pore water pressure, and 2- Changing in ground site response caused by softening of liquefiable soil [1]. Liquefaction assessment and its consequences have been investigated by many researchers [2]. Although, there are not enough studies to determine the effect of soil softening and liquefaction on the seismic ground response. The main purpose of this study is to evaluate the ground response for liquefiable sites. Hence, Specific Cumulative Strain Energy (SCSE) parameter is defined to consider the effects of earthquake duration and thickness of liquefiable layer.The results of amplification pattern were presented in both of the effective and total stress analyses.
