Case Studies in Cooperation with External Groups
Public confidence in the safety of the high-level radioactive waste program can be improved by meaningful participation in the decisionmaking process. Public involvement and the resultant...
An Integrated Systems Approach to Institutional/Technical Program Milestone Planning and Implementation in the Civilian Radioactive Waste Management Program
A broad spectrum of public and private sector institutions in the United States has concerns about the high-level radioactive waste management program. An integrated systems approach is...
The MD Design?A Cool Concept for Geologic Disposal of Radioactive Waste
The scheduled disposal capacity for spent nuclear fuel and other high-level radioactive wastes (HLW) is inadequate and the estimated supply of recoverable uranium for continued nuclear...
Damage-Tolerant Design of Deterministic and Nondeterministic Structural Systems
Many structures are exposed to very hazardous environments and they are likely to be damaged during their lifetime. Damage occurrence may cause a dramatic reduction in the safety of structural...
Optimization of RC Frames with Reliability Concepts
Analysis and design optimization are considered simultaneously for reinforced concrete frames. Global displacements were considered as design variables. The nonlinear behavior of the elements...
Downstream Danger from Sudden Discharges of Water
The sudden, unexpected release of water by hydropower facilities poses a threat to fishermen and boaters immediately downstream. The characteristics of the danger can be identified, however,...
Dams for the 21st Century
Water shortages around the world are mounting. Construction of dams, development of groundwater and improvement of irrigation practices are necessary to increase water supplies. Vast quantities...
A 1990's Strategy for Combined Sewer Improvements
On June 22, 1990, the Regional Water Quality Control Board issued the City of Sacramento a Cease and Desist Order. The Order required the City to examine the condition of, and flooding...
Nonlinearities and Imperfections in Creep Stability
The effects of material and geometric nonlinearities and imperfections on the 'safe-load-limit' and the 'safe-service-period' of structures...
Response Variability and Reliability of Stochastic Systems Using the Weighted Integral Method
After obtaining an exact expression of the stochastic stiffness matrix in terms of random variables called weighted integrals, the response variability and the safety index of stochastic...
Characteristics of Flow Over the Bucket with Gradually Varied Curvature
The bucket of a high spillway dam or a spillway tunnel is one of the parts that easily to be damaged by cavitation. A new type of bucket curve was suggested with gradually varied curvature...
Time-Domain Transmitting Boundary Condition in Fluid-Structure Interaction Studies
One of the major difficulties in the nonlinear analyses of fluid-structure interactions has been the lack of exact expressions for the transmitting boundary in the time domain. Researchers...
Gravity Dam Response Including Interaction Effects
The seismic response of 2D gravity dam-reservoir-foundation including the wave absorption effect along the reservoir bed is analyzed in frequency domain using substructure approach. The...
Dynamic Effect of Sediment on Dam Hydrodynamics
The dam-reservoir-foundation interaction problem has been studied by many investigators. A two dimensional model of compressible porous media is employed to analyze the dynamic response...
Numerical Simulation of Dam-Breaking Waves
Recently, as a high-resolution numerical technique, the Total Variation Diminishing (TVD) method is applied to Aerodynamic shock problems successfully. In this paper, a Total Variation...
System Identification Techniques for Inelastic Structures
A classical optimization algorithm is used to identify the parameters of a smooth hysteretic restoring force model, which can be used to describe the inelastic behavior of structures under...
Safe-Load-Limit of Plates in Cylindrical Bending
The derivation of a closed-form expression for the viscoelastic critical load of long thin plates undergoing cylindrical bending and made of a linear time-dependent 'solid'-type...
Pipeline Crossings
This proceedings of the Pipeline Crossings Conference, held on March 25-27, 1991 in Denver, Colorado, presents information on aspects of various pipeline crossings. It covers such broad...
Computer-Monitored Grouting
With grouting operations going on at many locations around the clock on a typical large dam-foundation project, how do you make sure that the designed mix is always being used and as-built...
Safeguarding History
Even monolithic marble monuments, such as the Thomas Jefferson Memorial, fall prey to materials deterioration. Now, sensitive instrumentation systems can document and analyze even the...
