IMPLEMENTATION AND VALIDATION OF A HYDRO-MECHANICAL ELASTOPLASTIC CONSTITUTIVE MODEL FOR FULLY COUPLED ANALYSIS OF UNSATURATED SOILS
(2017-05)
Unsaturated soils are commonly encountered in natural soil deposits above the ground water table and in civil infrastructure construction as compacted soils. In earthquake prone areas, problems arise from dynamic loading ...
Seismic Vulnerability of Residential Structures in Nicaragua
(2009)
In recent times, many parts of the world have seen a trend of increased construction with reinforced concrete and masonry block systems. These systems can provide excellent seismic resistance when they are designed by an ...
Influence of Facing on the Construction and Structural Performance of GRS Bridge Abutments
(2020-05-08)
Geosynthetic Reinforced Soil-Integrated Bridge System (GRS-IBS) technology has been developed significantly over the last decade through extensive support and promotion by the Federal Highway Administration (FHWA). It is ...
Hysteresis and dynamic effects in the relationship between capillary pressure, saturation, and air-water interfacial area in porous media.
(2006)
Air-water interfacial areas (A) were measured for multiple drainages (primary, secondary, and scanning) using a newly developed method, along hysteretic Pc-S curves representing natural drying/wetting processes. The ...
Regression and neural network modeling of resilient modulus based on routine soil properties and stress states.
(2006)
The laboratory results from the fourteen sites from fourteen counties were used to develop the relationships or models.
Nonlinear dynamic finite element analysis of steel frames with semirigid joints.
(1999)
In this study a nonlinear dynamic analysis computer program for planar steel frames with semi-rigid connections is developed. The semi-rigid connections are modeled as a massless rotational spring element. This element has ...
INFLUENCE OF HYDRAULIC HYSTERESIS ON THE MECHANICAL BEHAVIOR OF UNSATURATED SOILS AND INTERFACES
(2010)
Unsaturated soils are commonly widespread around the world, especially at shallow depths from the surface. The mechanical behavior of this near surface soil is influenced by the seasonal variations such as rainfall or ...
