LRFD for Engineered Wood Construction: ASCE Pre-Standard, Wood Industry Initiative
The structural wood community in the United States is in the process of developing a reliability-based consensus Load and Resistance Factor Design (LRFD) standard for engineered wood construction....
Reliability Analysis of Axially Compressive Members
In the steel structure design code (TJ17-74) in China, a single curve was adopted for designing axially compressive members and the reliability of the column analyzed previously was based...
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...
Study on Reliability of Actual Steel Structure Using Measured Data
The measurement of uncertainties was taken on an actually constructed steel structure. The stress and strain of each part of the structure are calculated based on the conditions assumed...
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...
Redundancy Evaluation of Steel Girder Bridges
The focus of this paper is on the use of redundancy measures in the evaluation of bridge systems. The emphasis is on the definition of system redundancy measures suitable for use by bridge...
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...
Effect of the Uncertainty About the Fatigue Limit on Highway Bridge Reliability
Current fatigue design specifications for welded steel highway bridges subjected to high traffic volumes require the design to be capable of resisting high-cycle, long life conditions...
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...
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...
The Prefab Tunnel
Jacking a prefabricated concrete arch through a railroad embankment to provide a new access ramp to the Don Valley Parkway in Toronto was done for the first time in North America. In September...
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...
One Power Plant, Two Job Sites
In response to the lingering questions about energy, officials from Vidalia, La initiated a plan in 1977 to build a hydroelectric plant at a site 90 mi northwest of Baton Rouge, where...
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...
A Supertrain Solution?
A high speed steel wheel rail line has been highly successful in France, where ridership has been very high. Financial backers were paid back in seven years, half the projected payback...
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....
Advances in Pipeline Materials and Design in Europe and North America
This paper presents an overview of various developments in materials technology and design procedures in the Western Hemisphere over the last 20 years. Some projections for anticipated...
Recent Advances in Structural Rehabilitation Techniques for Underground Sewer Pipelines
A great challenge for the coming years, if not decades, will be the repair, renovation and renewal of the existing sewerage systems in the Federal Republic of Germany in the interest of...
The NOVA SPAN Bridge System
The NOVA SPAN Bridge concept provides the basis for the design and construction of a new variant in the field of bridges and culverts which, in its performance and operation, incorporates...
