Abstract

The FEM was used to analyze the pattern of ground deformations caused by the potential slip of a known normal fault crossing a populated area of the city of Patras, Greece. The analyses were based on geological-geotechnical data of the area which were found in the literature. The results of the analyses showed that the maximum values of differential settlements were developed on the footwall of the fault. By assuming a safe limit of /3 = 1 /500 for the angular distortion of the buildings of the area, a critical zone was defined (based on the criterion /? > 1/500) having a width of 150 m, within which the buildings (and possibly other structures) run the risk of undergoing various degrees of damage, in case the fault is activated. The approach used herein may be applied to other situations o
