Evaluation of Lifetime Risk of Structures?Recent Advances of Structural Reliability in Japan
The Task Committee on Structural Safety and Reliability of the Japan Society of Civil Engineers has made survey of recent advances in the field of structural reliability. Consequently,...
Risk Acceptance Criteria for Performance-Oriented Design Codes
A general basis for the determination of 'acceptable risks' needs to be established to facilitate the development of risk-based performance-oriented design Codes....
Some Considerations on the Acceptable Probability of Failure
The acceptable failure probability of technical structures and systems is studied in this paper. The problem is approached from two points of view: the personal and the social point of...
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...
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...
Analysis of Bridge Maintenance and Rating Procedures
In the United States, bridges are routinely rated to evaluate their existing conditions. The formula used to evaluate bridges is called the Sufficiency Rating Formula. The formula uses...
Reliability-Based Bridge Life Assessment
Fatigue considerations have usually entered design codes as a secondary consideration and often under the guise of serviceability limits. Most engineers felt if the maximum stress ranges...
Development of a Safety Assessment System for Steel Bridge Erection Work
In order to secure safe execution of steel bridge erection work, development of a comprehensive checking system to set up safety countermeasures at the stage of construction planning prior...
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...
Comparison of a Practical Fragility Analysis of a Reactor Building with Non-Linear Monte Carlo Simulation
There are several conventional methods to assess seismic safety of nuclear power plants practically. In these methods, non-linear effect of the structural elements is considered with an...
A Plant for All Seasons
Collins, Eckley and Detweiler describe a successful energy conservation program at the Willow Lake Wastewater Treatment Plant, Salem, Ore. By funding the $4.59 million project with a combination...
High Wiring Act
Prendergast describes a project to construct a 345 kV transmission line over 313 mi in southwestern New Mexico, in which, due to environmental considerations and limited access, extensive...
Chicago's Loop: A New Approach
Reconstruction of the Wells St. Viaduct cleaned up a dangerous area just north of Chicago's Loop by providing a structurally sound approach for CTW commuter trains and a column-free...
Tales From Milwaukee's Underground
Written from RETC papers and interviews, this article is a status update on the Milwaukee Metropolitan Sewerage District's $2.1 billion Water Pollution Abatement program,...
A Doubling Design: Rochester's Expanding Airport
Few projects offer greater design challenges or pose more critical construction complexities than a new air passenger terminal, especially when that new terminal must be built on land...
Reciprocal Recycling
Municipalities are turning their wastes into valuable products through a unique combinations of water reuse and energy recovery. Reclaimed water, the product of the wastewater treatment...
Unlocking Arena Gridlock
The Charlotte Coliseum features a $22 million reversible lane system, which provides easier access to and from 8,000 parking spaces. To improve access to the arena, a 3.6 mi road extension...
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...
Small Project Management
Effective management of the small project must guard against overmanagement. Quick, accurate project tracking is required since small projects normally have short schedules, and adjustments...
Monitoring Vibration
Vibration monitoring for construction projects is increasing rapidly. Instrumentation for measuring structural response to blasting began in the mining industry with research by the U.S....
