Abstract

Estimation of soil behavior under dynamic loading has great importance in reducing the damage that may occur in an earthquake. For this reason, microtremor measurements were performed in a specific site to define dynamic behavior in terms of shear strain. The study area was divided into square shaped cells with 200m‘X’200m dimensions in order to implement the seismic microzonation criterion. Within the scope of microzonation studies, to 75 separate single station microtremor measurements, 7 microtremor array measurements were carried out and 75 boreholes data are collected. These field measurements were analyzed according to the Nakamura Method and estimated effective shear strain. One-dimensional (1D) equivalent linear seismic ground response analyses were performed for the sites where the microtremor array measurements were conducted. The results of microtremor analyses and 1D dynamics analysis were presented by Geographic Information System (GIS) and compared for research area.
