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...
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...
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...
Whatever Happened to Long-Term Bridge Design?
The Chairman of the Board of one of the leading engineering firms in the nation ponders the future of American bridges. In today's designing of bridges, Thomas R. Kuesel points...
Seam Examination
Charron discusses the importance of seam sampling in geomenbrane installation. In 1988, about 30 million mi of polyethylene geomembranes were used to line landfills, liquid impoundments,...
Creative Connections: Bridges as Art
Princeton University professor of civil engineering David P. Billington, at the invitation of civil engineering professors at Tokyo University, tours Japan and critiques several of the...
A Knowledge-Based Approach to the Design of Highway Bridge Foundations
This paper discusses the development of a prototype expert system using a commercially available expert system shell. The system is to be used for the selection of highway bridge foundations....
A Bridge Management System Module for the Selection of Rehabilitation and Replacement Projects
A procedure, developed for the state of Texas is reported, which determines an allocation budget for bridge replacement and rehabilitation projects, using multi-attribute criteria and...
A Microcomputer Aided Bridge Management System
This paper presents a microcomputer based software system suitable for a local agency which will permit a local bridge system to be systematically evaluated with the use of a bridge management...
Florida Bridges Beat the Clock
Today, when budget overruns and delays on construction projects are the rule more than the exception, 11 precast segmental balanced cantilever bridges on two contracts were recently completed...
On the Drawing Board
Reliable and quantitative nondestructive evaluation (NDE) methods for construction materials of wood, concrete, masonry and structural steel are needed. NSF program director John Scalzi...
Bridges Under Surveillance
Although bridge monitoring is still in its infancy, research, pilot studies and field work are underway across the country. While today it's still a pie-in-the-sky goal, the...
Northumberland Strait Crossing Project?A Public-Private Venture
This major project has challenged the Canadian Government to produce innovative requirements in environmental planning, financing and security, and facility performance. It requires a...
