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...
Strategies for Bridge Inspection Using Probabilistic Models
This paper describes the application of probability analyses in planning an inspection program for highway bridges. When damage in the form of fracture and cracking is the major concern,...
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...
Bridge Live Load Models
This paper describes the analysis of weigh-in-motion data and the conclusions drawn. Statistical distributions of the effects induced in typical bridges due to single vehicle events are...
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...
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...
Reliability and Redundancy Assessment of Prestressed Truss Bridges
Methods for the assessment of the reliability and redundancy of post-tensioned trusses are suggested. The effect of tendon layout on the reliability and redundancy of post-tensioned trusses...
On the Dynamic Response of Bridges by Oscillating Vehicles on Rough Surfaces
The spectral theory is applied to the response of bridges under a Poissonian stream of vehicles moving with constant speed over the bridge. The vehicles are modeled as oscillators with...
Approximate Reliability Analysis of Highway Bridges Under the Action of Random Vehicles?In Relation to an Interchange Bridge of China
In relation to an interchange curved bridge of China, a simple method by FSE for analysis of stochastic vibration has been proposed. The random vibration characteristics of bridge structures...
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,...
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...
Vibration Tests and Damage Detection of P/C Bridges
A three-span countryside P/C bridge has been found to have excessive deflections in two of the three spans. It is reported that the prestresses in tendons of two girders of different spans...
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...
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...
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...
