RISFinite-Element Model for Urban Pavement Rutting: Analysis of Pavement Rehabilitation Methods
Publisher: American Society of Civil Engineers
Abstract: This paper concerns analysis of rutting of urban pavements using finite-element modeling, which takes into account the nonlinear behavior of the pavement materials and the complex traffic condition. A viscoplastic constitutive ...
Instability and Static Liquefaction on Proportional Strain Paths for Sand at Low Stresses
Publisher: American Society of Civil Engineers
Abstract: The behavior of Hostun RF sand on proportional strain paths at low confining pressures (20 to 100 kPa) is considered in this paper. In such paths, a constant dilation rate is imposed during shear. The usual features of ...
Failure and Dilatancy Properties of Sand at Relatively Low Stresses
Publisher: American Society of Civil Engineers
Abstract: Analysis of geotechnical problems concerned by low confinement such as design of shallow foundations and analysis of slope stability and soil liquefaction requires modeling of the soil behavior at low stresses. This note ...
Influence of Nonlinearity on the Stress Distribution in the Soil—Application to Road Engineering Problems
Publisher: American Society of Civil Engineers
Abstract: The Boussinesq theory for the distribution of stresses in a half-space resulting from surface loads is largely used in road engineering. It is based on the assumption of linear-elastic homogeneous isotropic half-space for ...
Block Element Method for the Seismic Stability of Rock Slopes
Publisher: American Society of Civil Engineers
Abstract: The seismic stability analysis of rock slope is implemented using a block element method (BEM) in this paper. Based on the formulations of the matrices of stiffness, mass, and damping, the dynamic governing equation for ...
Analysis of Arch Dams Using Coupled Trial Load and Block Element Methods
Publisher: American Society of Civil Engineers
Abstract: This paper presents the use of the trial load method and the block element method with elastoviscoplastic discontinuities for analysis of arch dams. The arch dam is considered as an arch-cantilever system and the foundation ...
Optimum Level of Shear Wall Curtailment in Wall-Frame Buildings: The Continuum Model Revisited
Publisher: American Society of Civil Engineers
Abstract: The continuum model constitutes a simple and efficient tool to analyze high-rise wall-frame buildings. It has been commonly used in recent decades to analyze the behavior of these structures. The related equations are ...
Composite Element Analysis of Gravity Dam on a Complicated Rock Foundation
Publisher: American Society of Civil Engineers
Abstract: This paper presents the formulation and application of a composite element method, which is intended for numerical modeling of discontinuous rock masses. This method allows analysis of fractured rock masses using regular ...
Analysis of Gravity Dam on a Complicated Rock Foundation Using an Adaptive Block Element Method
Publisher: American Society of Civil Engineers
Abstract: In this Technical Note, the adaptive block element method of rock masses is formulated, in which the elastoplastic characteristics of both rock blocks and discontinuities are taken into account. The concept of an overlay ...
