Structural Optimization Based on Component-Level Reliabilities
A minimum-weight optimum design procedure is proposed including the reliabilities of various elements in a structure as constraints. The reliability indices corresponding to the various...
Limit States Design in Masonry
This paper reviews some aspects of limit states design for masonry structures based primarily on experience with a new Canadian code. Steps in an advanced second order safety index analysis...
Reliability of Miter Gates
A new approach for the reliability calculation of miter gates is presented. The reliability and hazard functions are related to the surficial wear of miter gates on their horizontal sill....
Reliability-Oriented Materials Design of Composite Materials
A basic formulation for evaluating safety index of unidirectional fiber reinforced laminate is presented. The proposed formulation is based on in-plane failure criteria of composite laminate...
Optimal Inspection Planning for Fatigue Damage of Offshore Structures
A formulation of optimal design, inspection and maintenance against damage caused by fatigue crack growth is formulated. A stochastic model for fatigue crack growth based on linear elastic...
The Effect of Repeated Inspections on the Reliability Degradation Due to Fatigue Crack Growth
The effect of repeated in-service inspections on the reliability degradation due to fatigue crack growth is investigated based upon a stochastic fracture mechanics. A method to evaluate...
Seismic Reliability Analysis for Elevated Pressure Vessels
This paper presents two approaches for assessing the seismic reliability of elevated pressure vessels. A discretized mass mechanical system is used to model the dynamic effects of liquid...
Reliability of a Suspension Bridge Under Traffic Flow
The problem of reliability of a single-span spatial suspension bridge under random highway traffic is considered. The displacements of the bridge are described by coupled, non-linear,...
Simulation of Radionuclide Retardation at Yucca Mountain Using a Stochastic Mineralogical/Geochemical Model
This paper presents preliminary transport calculations for radionuclide movement at Yucca Mountain using preliminary data for retardation parameter distributions based on mineral distributions....
Container Material Selection, Modeling and Testing
Virtually all of the approximately 40,000 high-level nuclear wast containers to be emplaced at Yucca Mountain must remain intact for 1,000 years to satisfy Nuclear Regulatory Commission...
MIIT; International In-Situ Testing of Simulated HLW Forms?Preliminary Analyses of SRL 165/TDS Waste Glass and Metal Systems
The first in-situ tests involving burial of simulated high-level waste (HLW) forms conducted in the United States were started on July 22, 1986. This effort, called the Materials Interface...
Near-Field Modelling for the Safety Assessment of French High-Level Waste Repositories
In assessing the safety of a French high-level waste repository, the fluxes of radionuclides released by the near-field into the geosphere are modelled by the CONDIMENT source code. This...
Soluble High-Level Waste Decontamination and Disposal at the Savannah River Site
The high-level radioactive waste that has accumulated at the Savannah River Site is stored in large underground steel tanks. Programs to remove the soluble waste from the storage tanks,...
The DWPF Product, and Its Qualification Program
The Defense Waste Processing Facility (DWPF) at the Savannah River Site (SRS) will be the first facility in the nation capable of immobilizing high-level nuclear waste. Production of DWPF...
Estimate of the Source Term for a Repository Surface Facility From the Routine Processing of Spent Fuel
The potential for release of radioactive material from the proposed handling and processing of spent nuclear fuel in a surface facility for a geologic repository was evaluated. The potential...
Fabrication and Closure Development of Nuclear Waste Containers for Storage at the Yucca Mountain, Nevada Repository
U.S. Congress and the President have determined that the Yucca Mountain site in Nevada is to be characterized to determine its suitability for construction of the first U.S. high-level...
Space Debris?A Design Consideration
With the increased use of space by manned or unmanned missions, it has become necessary to include yet another parameter in the design of spacecraft, namely, the effect of a probable impact...
A Space Station Trash Recovery and Recycling System
The quantity of trash produced on the Space Station during its lifetime will be substantial and will include useful waste materials. Given the high cost of transportation to orbit, it...
Composting for Lunar Agriculture
Alternative technologies for the microbially mediated biological oxidative transformation (composting) of human wastes and other organic wastes are presented. Batch mode and continuous...
New Interdisciplinary Engineering Design Course in Planetary Materials and Resource Utilization
A new senior/graduate-level course addressing topics of planetary materials and resource utilization was given at Michigan Technological University in the spring of '89. The...
