Performance of New York's Long-span Bridges
This paper is a work-in-progress report on a database on the performance of long-span bridges located in New York State and built between 1801 and 1993. Of the 68 long-span bridges - bridges...

An Inductive Knowledge-Based System for Mitigation of Bridge Fabrication Errors
Fabrication and erection of steel bridges are very error-prone processes. Bridge engineers at the Kansas Department of Transportation (KDOT) felt that there is a need for the development...

Seismic Evaluation of the Macy Street Bridge, Los Angeles, California, Using 3-D Nonlinear Pushover Methodologies
Nonlinearity of the overall bridge response has begun to be incorporated in the design process through a method known as nonlinear static pushover analysis, and this step is now being...

Nonlinear Analysis and Experimental Validation of a Stiffening Truss Chord of the Golden Gate Bridge
Finite element analyses of a stiffening truss chord of the Golden Gate Bridge were conducted by the authors as part of a comprehensive seismic retrofit project conducted by T. Y. Lin International...

Application of the FESWMS-2DH Software to Solve the Navigation Problem at EL-Menya Bridge in Egypt
The purpose of this paper is to introduce the application of a two-dimensional Finite Element Surface Water Modelling System on a navigation problem located along the Nile river in front...

Expert System for Bridge Scour and Stream Stability
Significant engineering judgment is required to ascertain the scour susceptibility of bridges. This judgment is typically acquired through many years of experience. This paper describes...

BRICAL: A Multimedia Intelligent Educational System for Bridge Engineering
This paper discusses the development of a multimedia intelligent educational prototype system for bridge engineering called BRICAL. BRICAL uses information networks to express the relationships...

Bridge Condition Rating Using Fuzzy Sets and an Eigenvector of Priority Settings
A simplified methodology for combining the condition rating of the various elements of bridge components (deck, superstructure or substructure) is developed using a multi-attributive decision...

Conceptual Design Using Evolutive-Cognitive Computing Techniques
The paper concerns the development of a computer-based capability for conducting conceptual design using emergent(self-organizing) computing paradigms that arrive at a solution through...

Testing and Predicting the Movement of a Drilled Shaft in New Mexico
The New Mexico State Highway and Transportation Department (NMSH&TD) have been using drilled shafts for supporting bridges in the State of New Mexico. Several drilled shafts were...

Comparison of Settlement Predictions for Single Piles in Sand Based on Penetration Test Results
The analysis of settlement for driven piles in cohesionless soils is a complex soil structure interaction problem. The total settlement for such a pile is generally considered to be the...

Settlement and Deformation Response of a Bridge Footing on a Sloped Fill
The problem of settlement of spread footings located within or near granular slopes has been investigated in the laboratory using a large testing facility. Based on these results, footings...

Settlement Measurements of 50-ft High Embankments at the Chesapeake & Delaware Canal Bridge
This is a case history of instrumented settlement measurements on 49 to 56' (15-17 m) high bridge approach embankments of Delaware State Route 1 crossing of the Chesapeake & Delaware...

Numerical Modeling of Bridge Approach Settlement with Foundation-Embankment Interaction
Bridge approach settlement is one of the major problems facing the transportation agencies responsible for road construction and maintenance in the United States and in many other countries...

Tolerable Deformations
Current criteria for tolerable movements of buildings, bridges and other structures are reviewed. Tolerable values of total and differential settlement, relative rotation, relative deflection...

Demonstration Project for Scour Instrumentation
A Federal Highway Administration (FHWA) Demonstration Project was developed to facilitate technology transfer of instrumentation related research to the highway industry. The objective...

Real-Time Data Collection of Scour at Bridges
The record flood on the Mississippi River during the summer of 1993 provided a rare opportunity to collect data on scour of the streambed at bridges and to test data collection equipment...

Low-Cost Bridge Scour Measurements
This paper reports on the use of a low-cost, highly portable sonar system. The ease of use of the instrument and the short time required to make measurements should make this system valuable...

Field Performance of an Acoustic Scour-Depth Monitoring System
The Herbert C. Bonner Bridge over Oregon Inlet serves as the only land link between Bodie and Hatteras Islands, part of the Outer Banks of North Carolina. Periodic soundings over the past...

Practical Method for Calculating Contraction Scour
Total scour at bridge crossing waterways consists of long-term aggradation or degradation of the streambed, contraction scour and local scour at the piers and abutments. This paper will...
