Small-strain behavior is a key indicator for assessing the performance of compacted fills.
Compaction conditions, ie, initial moisture content and applied energy, govern compaction …

Shear modulus (G) and damping ratio (D) are efficient and important parameters in
estimation of seismic response of a site. Recently by development of the advanced …

Geotechnical design for unsaturated soils requires an understanding of their fundamental
characteristics. In this paper, in order to study the monotonic, cyclic and post-cyclic …

Recent code provisions for building and other structures (1994 and 1997 NEHRP
provisions, 1997 UBC) have adopted new site classification. The new site classification …

Nonlinear site response analysis is widely used in evaluating local soil effects on
propagated ground motion. Nonlinear and dissipative behavior of soil deposits are modeled …

Soil properties can completely change the ground motion characteristics as they travel from
the bedrock to the surface because, soil as a low-pass filter, may amplify or deamplify …

The influence of matric suction as a stress state variable of unsaturated soil on shear
modulus and also nonlinearity of soil has been recognized in several researches. Therefore …

مباحث مربوط به مکانیک خاکها‌ی غیراشباع که اخیراً بیشتر مورد توجه قرار گرفته و بسیاری از
مفاهیم مکانیک خاک کلاسیک را به چالش کشیده است نشان می‌دهد توصیف محیط‌های متشکل از سه …‎
