Instant Hydro Forecasting
Two new software programs developed by a San Francisco-based engineering firm determine hydropower potential, best site configuration, and best economics for hydroelectric projects. One...
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...
Explicit Integration of Boundary Integral Equations in the Frequency Domain for Wave Scattering Problems
The goals of this article are: (1) to present an efficient method for the integration of the boundary integral equations for wave scattering problems and (2) to apply this method to the...
A BEM-Perturbation Technique for Membrane Structures
Most of the previous work has concentrated on the free vibration problem. The present paper examines the problem of low frequency forced vibrations of a membrane due to an oscillatory,...
Nonlinear Quasi-Static and Transient Response Analysis of Shallow Shells: Formulations and Interior/Boundary Element Algorithms
Nonlinear integral equations are derived for the representation of displacements of shallow shells undergoing moderately large, quasi-static or dynamic deformations. A combined interior/boundary...
A Study on Non-Conforming Boundary Elements in Elastomechanics
This work is a critical study on the performance of non-conforming boundary elements in three-dimensional elastomechanics. The pervasive way of implementing the boundary element method...
3-D Flexible Embedded Machine Foundations by BEM and FEM
A study on the dynamic response of three-dimensional flexible massless foundations of arbitrary shape, embedded in a homogeneous, isotropic and linear elastic half-space and subjected...
Harmonic Vertical Pile Response in Non-Homogeneous Medium
This paper describes the application of the boundary element method to determine the steady state response of vertically loaded floating piles in a non-homogeneous medium in which the...
Vibration Isolation of Structures From Surface Waves in Layered Soil
This work deals with the problem of isolation of structures from ground transmitted surface waves generated by machine foundations. The isolation is accomplished by means of rectangular...
Structural Optimization Under Conditions of Uncertainty, with Reference to Serviceability and Ultimate Limit States
Probability concepts and methods are rapidly gaining ground in the search for more rational approaches to structural optimization. Under conditions of uncertainty, the risk of unfavorable...
Connection Panel Zone Deformation in Steel Frames
Conventional analyses of frameworks are usually carried out without considering the effect of panel zone deformation on frame behavior. As a result, center-to-center distances rather than...
Water Project Design and Safety: Prospects for Use of Risk Analysis in Public Sector Organizations
After offering some initial definitions, the authors will describe a highly structured model of risk analysis and water resources decision making in the public sector. The primary emphasis...
Approaches to Acceptable Risk
Acceptable risk has numerous meanings, that are derived from its having been defined in multiple arenas and by multiple groups. This paper describes several approaches to the question...
The Sociocultural Context of Coping with Risk and Uncertainty
In the context of the present conference, selected points will be underscored about the centrality of risk and uncertainty in contemporary society, aspects of judgment and decision making,...
A System Framework for Engineering Risk Analysis
A mathematical system framework is developed to model a series of criteria called performance indices (PI) related to engineering risk in water resources. Such criteria include reliability,...
The Status of Risk Analysis in Water Resources Engineering
Acceptance of probabilistically based risk-analysis evaluation methods among water resources engineers is rather slow, as it is among other engineering specialities. Academic researchers...
The Risk Factor in Water Resources
Risk is inherent in nature and society, while uncertainty depends on investigations. Decision making in water resources is most often a deterministic selection of dimensions which divide...
U.S. Bureau of Reclamation Use of Risk Analysis
The United States Bureau of Reclamation (USBR) has been using risk analysis techniques in assessments for management decisions. Before presenting USBR practice and experience, the paper...
Some Perspectives and Philosophies on Risk-Based Decision Making in Water Resources
The authors have selected four perspectives of the water resources decision problem that illustrate how formal risk-based approaches may be applied - an economic perspective, an environmental...
Environmental Considerations in Risk-Based Decision Making in Water Resources
In the hypothetical Royal River Project there are several factors pertaining to environmental issies; these factors have a bearing on selection among the several alternatives and lead,...
