Time-Domain Dam-Reservoir-Interaction Analysis Based on Boundary Elements
For a reservoir with an arbitrary shape of the upstream face and of the bottom including an adjacent regular part of constant depth extending to infinity, the hydrodynamic-stiffness matrix...
Dynamic Response of Massive Block to Transient Rayleigh Waves
The study explores the dynamic behavior of a rigid massive block placed on a homogeneous elastic half-space soil medium and subjected to transient Rayleigh waves. The treatment of the...
Evaluation of Sediment Transport and Friction Factor Equations Using MOBED
Three sediment transport rate equations and the same number of friction factor equations for mobile boundary channel flows were evaluated using a mobile boundary flow model called MOBED....
Costs of Truck Related Highway Damage to Alaska
The cost of pavement damage to the State of Alaska for truck traffic continues to be a very controversial topic. There is no simple answer since this cost is dependent upon pavement strength,...
Survey of Airport Pavement Distress in Cold Regions
The most common pavement problems were associated with non-traffic related phenomena and included pre-existing cracks reflecting through asphalt concrete overlay (in two years or less),...
Alyeska Reroutes Trans-Alaska Pipeline at MP 200
This paper discusses the 1985 wintertime repair/reroute to the Trans Alaska Pipeline System (TAPS). The rerouted pipe was approximately 4000 feet long and cost approximately 27 million....
Wastewater Plant Cold Weather Operational Problems
A questionnaire survey was conducted at biological wastewater treatment facilities in northern New England. Problems associated with various unit processes, due to cold weather operations,...
Legal Concerns in Cold Regions Engineering and Construction
For a variety of reasons the potential for the imposition of liability and the potential for comparatively large damage claims is greater in cold regions. It is the purpose of this paper...
Dynamic Soil-Structure Interaction by the Boundary Element Method: A Comparison Study
A comparison study of three Boundary Element Method approaches is attempted on the basis of a typical three-dimensional, dynamic soil-structure interaction problem. The vertical transient...
Selection of Performance Levels for Longitudinal Barriers
There is a demand within the highway community for multi-service level safety features, including traffic barriers. The need has become more acute in recent years as revenues decline and...
Performance of Highway Traffic Barriers
This paper describes an investigation of traffic barrier performance in New York State. A one-year sample of all traffic-barrier accidents in the state was obtained from Department of...
Assessment of Safety Impacts of Highway Projects
In this paper the safety impact of highway improvement and maintenance activities is examined in terms of accident reduction potentials of these activities. There are three causes of accident:...
Green's Function Implementation for Pile Analysis
This paper describes the implementation of a new Green's function based on a layer stiffness approach in a boundary element analysis of harmonically loaded pile groups embedded...
Diffraction Forces on Axisymmetric Bodies
Use of a Green function satisfying the governing differential equation and all boundary conditions except those on the boundary of the structure yields an integral equation, when these...
Boundary Zone Superposition Method for Linear and Nonlinear Dynamic Analysis of Infinite Domain Problems
The method is applicable to problems where input loads are imposed from within the finite element model or to problems where disturbances outside the finite element model generate input...
Innovations in the Design of Electrical Transmission Structures
New concepts are being advanced for the design of electrical transmission structures. The papers in this book cover the following: weather-element loading conditions, structural options,...
Soil-Structure Interaction in Seismic Environments
Soil-structure interaction depends on the mass, stiffness and the damping of the structure as well as on the geometry and embedment of the foundation and on the properties of the soil....
Parking Lot Gets White Top
The many-acre parking lot at the Valley Fair Mall shopping center in Salt Lake City, Utah is described. In 1985 the asphalt pavement was overlaid with concrete, making it one of the relatively...
An Evaluation of Sediment Resuspension Parameterizations
The recent attention to managing surface water toxic substances has resulted in a number of modeling approaches, all of which to a great or lesser extent require accurate treatment of...
Application of the BEM to Elastodynamics in a Three Dimmensional Half Space
The boundary integral equations (BIEs) are formulated for scattering problems of elastic waves by a cavity or a crack in a three dimensional half space. Two formulations based on the Green's...
