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...

Safety Plans for Buildings, Structures and Technical Facilities
Safety is an important quality feature and depends on all activities within the building process. The safety concept must therefore consider all phases of the building process, from the...

Secure Landfills: Reliability-Based Analysis and Design
A framework is outlined for reliability-based analysis and design of secure landfills. Reliability, R, is the estimated probability landfill leakage, Ql, is below an allowable limit, Qf;...

Lifetime Behavior of Wood Structural Systems
Reliability based design of wood structural systems requires knowledge about the lifetime behavior of the system. The 50 year lifetime behavior of wood floors and flat roofs was examined...

Optimal Strategies for Design, Inspection, and Repair of Fatigue-Sensitive Structural Systems Using Risk-Based Economics
The fatigue reliability and maintainability process for a marine structure (caisson platform) is studied. Reliability analysis, performed by Monte Carlo, quantifies the improvement in...

Damage Assessment Based on Repairability Criterion
This paper discusses the assessment of damage of protective structures based on the repairability criterion. The variables of the repairability are the amount of repair, repair cost, repair...

Damage Assessment of Bridge Structures by System Identification
A method for the damage estimation of bridge structures under seismic ground excitation is developed based on system identification approach. The dynamic behavior of a damaged structure...

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...

Recent Seismic Risk Studies of Nuclear Power Plants: An Overview
Seismic probabilistic risk assessments (PRA) are conducted to estimate the frequencies of occurrence of severe core damage, serious radiological releases, and consequences in terms of...

Probability Based Bridge Safety Analysis
Traditional methods of quantifying safety of highway bridges have been associated with deterministic analysis. However, ascertaining the true measure of safety, or reliability, should...

Reliability Assessment and Reliability-Based Rating of Existing Road Bridges
A practical reliability model for the safety assessment and rating of existing R.C. bridges are developed by explicitly incorporating the degree of deterioration and damages based on available...

Research on Structural System Reliability of Cable-Stayed P.C. Railway Bridge Across Hong-Shui River
This paper analyses the structural system reliability of cable-stayed bridge by using the modified all failure modes. The concept of the structural subsystem is used to help the selection...

The Nessus Software System for Probabilistic Structural Analysis
The Probabilistic Structural Analysis Methods (PSAM) project developed at SwRI integrates state-of-the-art structural analysis techniques with probability theory for the design and analysis...

Incremental Assembly Stage Concepts for Space Station Freedom: Structural Design and Verification
The design and development of the U.S./International Space Station Freedom poses extreme technical and management challenges to the NASA/industry team. A comprehensive system engineering...

System and Utilization Study of Japanese Experiment Module for International Space Station
The paper briefly reviews the overall system study of Japanese Experiment Module (JEM) which consists of Pressurized Module, Exposed Facility and Small Remote Manipulator System (RMS)....

HELP is on The Way
Hill and Davies describe current progress on the development of a Heavy Vehicle Electronic License Plate (HELP) system in the United States. The HELP system concept combines automatic...

Column Separation in Pumped Pipelines
Pressure transients are common occurrences in water supply systems. Pipeline standards and design/testing techniques will normally provide sufficient protection for transmission and distribution...

Comprehensive Leak Detection Survey and Benefit/Cost Analysis
Fort Carson, Colorado was the site of a comprehensive leak detection investigation of the potable water system with the express purpose of quantifying the benefits to be derived by a military...

Valve Control to Avoid Column Separation in a Pipe
Maximum pressures in a pipeline can be reduced significantly by closing the valve in an optimal manner. Such an optimal valve closure policy may result in some situations in minimum pressures...

Optimal Design of Water Transmission Mains
Capital cost for constructing a water transmission main includes cost of the pipeline and its associated installation costs. Also included in the capital cost is the cost of a pump station....
