EFFECTS OF SPATIAL VARIABILITY OF SOIL PARAMETERS ON THE DIFFERENTIAL SETTLEMENT AND THE INTERNAL FORCES OF A FRAME STRUCTURES Session: General Geotechnique and Engineering Geology / Géotechnique générale et géologie de l'ingénieur Mohamad Nazieh Jlilati, Widener University (United States) One of the distinguishing features of geotechnical reliability analysis, compared to other structural reliability analysis such as concrete and steel structures is material properties are different from site to site. The sources of uncertainties in reliability analysis are usually classified in four categories, namely physical uncertainty, model uncertainty, statistical uncertainty and gross error. The purpose of this study is to quantitatively evaluate the impact of physical uncertainty of soil on the differential settlement of circular shallow foundations on statistically homogeneous elastic ground and the stresses in a 1st degree indeterminate frame structures. The settlement and the differential settlement were predicted; the stresses had not exceeded 1.2 % increment of the homogenous conditions in the studied frame structure.
