Stresses and Displacements in Cross-Anisotropic Soils
An analytic investigation is presented on the effect of soil cross-anistropy on surface displacements and stress distributions in a homogeneous thick soil deposit (halfspace) subjected...

Resilient Characteristics of Brazilian Soils
Resilient properties of twenty soil samples from subgrades, sub-bases, and mechanical stabilized soil bases of flexible pavements in the South and Southeast of Brazil were evaluated. Soils...

Application of Modulus Degradation Model of Clays
A degradation model is applied in conjunction with different soil models and stress-strain relations to site response analyses during earthquakes. To evaluate the effects of degradation,...

Measured Performance of a Laboratory Culvert
This study shows that the behavior of a soil culvert system can be modeled by a linear finite element program and a mathematical solution of a hole in an elastic sheet reinforced by a...

Deformation Analysis for Braced Excavation in Clay

Settlements of a Tower on Residual Soil

Superplastic Cone-Shaped Sandwich Cores
A new sandwich core is formed by using the superplastic sheets and the vacuum pressure- or gas pressure-forming technique, or both. It is capable of providing opportunities for structural...

Cyclic Axial Response of Single File
A number of solutions have been obtained for a typical offshore pile, to determine the influence of a number of the input parameters on the computered cyclic response. More significant...

Characterization of Asphalt Emulsion Treated Bases
A laboratory investigation was performed to characterize cold mixed asphalt emulsion treated bases. Indirect tension, resilient modulus, Hveen and water damage techniques were used in...

Field and Laboratory Determination of Soil Moduli
A field geophysical investigation was performed to determine the shear and Young's moduli as a function of depth for a site in southern Ohio. This investigation included crosshole,...

Dynamic Shear Modulus of Treated Expansive Soils
Dynamic shear modulus of expansive soils treated with lime, salt, and lime-salt combination has been determined by the resonant column technique to study the parametric effects of confining...

Dynamic Properties of Two Marine Clays
The effects of stress history on the dynamic properties of two marine clays have been investigated by means of resonant column and cyclic triaxial tests. It is shown that both the overconsolidation...

Dynamic Properties of Frozen Silt Under Cyclic Loading
Cyclic triaxial tests were conducted to evaluate the dynamic properties of laboratory prepared samples of frozen silt under simulated earthquake loading conditions. Dynamic Young's...

Seismic Response of Cohesive Marine Soils
A nonlinear hysteretic soil model and an energy transmitting boundary are utilized in the method. The model allows a failure criterion to be incorporated and accounts for stiffness degradation...

Hysteretic Fracturing Endochronic Theory for Concrete
An improved endochronic nonlinear triaxial constitutive relation for concrete is developed: (1)In addition to plastic strain increments proportional to stress tensor, fracturing strain...

Soil Modulus and Longitudinal Pipeline Stresses
Two cases of practical interest in pipeline installation and maintenance are examined: the lifting of a continuous line by a pair of slings and the lifting of a single sling. Theoretical...

Disaggregation of Streamflow Volumes
A disaggregation model, which differs from those developed by Valencia and Schaake (VS) and Mejia and Rousselle (MR) (referred to as the HB model), was developed specifically to preserve...

Static and Dynamic Laterally Loaded Floating Piles
A previously formulated beam bending finite element of circular cross section enabled obtaining an economical solution to the three-dimensional problem of static and dynamic laterally...

Resilient Response of Two Frozen and Thawed Soils
Values of resilient modulus and Poisson's ratio were determined for silt and clay subgrade materials subjected to seasonal freezing and thawing. A new technique employing...

Settlement of Single Piles in Nonhomogeneous Soil
An analysis, previously developed for evaluating the settlement of a pile in homogeneous soil, is extended to the case of nonhomogeneous soils. Comparisons with finite element solutions...
