ABSTRACT
Soils susceptible to liquefaction behave like liquids under cyclic loading due to increasing pore pressure causing loss of the bearing capacity. Turkey is one of the most earthquake-prone countries in the Europe. In this study, five different boreholes representing the soil of Sakarya Akyazi in Turkey were investigated in terms of the risk of liquefaction for different scenarios. First, the liquefaction potentials were investigated for different profiles. Later, the spectral response proposed by the new Turkish Building Code was calculated using the new seismic maps. In order to evaluate the performance of TBC, the spectral response recommended by EUROCODE was estimated, and the non-linear response of soil profiles were compared with the versions offered by the codes. The performance of codes were determined by how well they represent the plateau between the corner frequencies of the response of the soil and the similarities and differences of the regulations were discussed.
