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...
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...
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...
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...
Investigation & Rehabilitation of Seattle's Tolt Pipeline
Seattle Water Department's Tolt Pipeline brings water 24 miles from storage in the Cascade Mountains into city and suburban distribution systems. Twenty-three miles of this...
In-Situ Evaluation of 30-In. (762-mm) Diameter Prestressed Concrete Lined-Cylinder Pipeline
The results of an extensive investigation to evaluate the in-service condition and future serviceability of an existing lake water make-up pipeline are briefly described herein. The pipeline...
Combined Load Testing of Prestressed Concrete Cylinder Pipe
A series of combined load tests were run on prestressed concrete cylinder pipe in order to evaluate a proposed new method of design for pipe made to AWWA Standard C301. These tests involved...
Innovative Concept for Prestressed Pressure Pipe
A new design and manufacturing concept was developed by General Atomics for prestressed pressure pipe. With this new concept, patented in the U.S. and in the major industrialized nations,...
Pipeline Design and Construction Using High Density Polyethylene (HDPE) Pipe
All pipelines and pipe materials must be designed and constructed to address the limitations of the pipe and fittings in order to insure acceptable performance of the line. Conventional...
Cheyenne Stage II Water Delivery Pipeline and Shoshone Municipal Water Supply Pipeline
This paper deals with the design and construction aspects of two pipeline projects in Wyoming. Located in southeastern Wyoming, the Cheyenne Stage II Water Delivery Pipeline consists of...
Pipeline Explodes, Two Dead, 31 Injured, 11 Homes Destroyed
A high pressure pipeline in a suburb of San Bernardino, California exploded in a deadly fireball on May 25, 1989. Damaged as a result of a train wreck several weeks earlier, or by the...
Analysis of Alternative Pipe Materials for a Major Public Water Agency
A major southwestern public water agency has historically specified the exclusive use of prestressed concrete cylinder pipe (PCCP) for large diameter water transmission mains. Due to the...
Twin Pipeline Crossing of the Fraser River
A new creek water supply was developed for the communities of Mission and Matsqui, British Columbia, Canada, in the early eighties. Over 60 kilometres of 450 mm to 900 mm diameter ductile...
Relining of Jordan Aqueduct, Reach 3
As pipelines approach their life expectancy, they may need to be replaced. Or in some instances, replacement is needed much sooner due to defective pipe. Normal replacement operations...
Field Experiment on Behavior of Continuous Water Main with a Miter Bend
A field experiment was conducted to investigate behaviors of a buried continuous steel water main with a 90-degree miter bend subjected to internal pressure and ground settlement. Deformations...
