Talmadge Bridge Replacement
This paper discusses the design of the main spans and approach spans for the replacement of the Talmadge Bridge for the Georgia Department of Transportation. The design of the concrete...
Monitoring Stay Cable Forces During Construction of the Natchez Trace Parkway Arch Bridge
This paper describes how cable-stay forces were indirectly quantified through the use of simple field measurements. A system was developed and delivered to the contractor and used to make...
Towards Structural Strength and Safety Evaluation Within Bridge Management Systems
Bridge management systems being implemented by transportation departments in the United States are limited in their ability to consider structural strength and safety when preparing recommendations...
Comparison of Bridge Deterioration Rates
This paper presents the results of a study of rates of deterioration of steel and prestressed concrete bridge superstructures. The results indicate that age is the primary determinant...
Historical Considerations for New Jersey Viaduct
An Historical Bridge Alternatives Analysis report prepared for New Jersey Department of Transportation (NJDOT) for Route 1&9 S.B. viaduct in Newark, New Jersey evaluated the options...
Seismic Evaluation of the Tied-arch Bridge Across the Mississippi River on I-40
The bridge reported in this paper is a two-span steel tied-arch bridge supported on massive caisson foundations. Site specific seismic studies were carried out to establish the ground...
Seismic Response Studies on a Two Span Slab-On-Girder Bridge
A new type of self-equilibrating snap-back (quick-release) test setup is employed to investigate the transverse dynamic response of a two-span continuous slab-on-girder highway bridge....
Seismic Performance of Railway Bridges
Historically, the seismic performance of railway bridges in the U.S.A. has been very satisfactory during earthquakes of this century. There are many possible factors contributing to this...
Seismic Research Program for Highway Construction
This paper provides an overview of the highway research program being conducted by the National Center for Earthquake Engineering Research (NCEER). This six-year program, which is sponsored...
Seismic Study of Historic Bridges in Eastern United States
The main objective of this paper is to study the Barrackville bridge and its response in resisting static and seismic loads. Since the design was based on controlled deflections, the analyses...
Continuity in Precast Prestressed Concrete Girder Bridges
An experimental study conducted to evaluate the behavior of pretensioned bridge members made continuous with a cast-in-place concrete slab and diaphragm is summarized. In this study, the...
A Study of Jointless Bridge Behavior
The pressing need for maintenance free and low construction cost bridges, has increased the interest and activity in building integral or jointless bridges. The investigation of the behavior...
Design of Box Girder Bridges by Nonlinear Theory
A modified design procedure applicable to a large number of conventional box girder bridges with longitudinally-stiffened flanges has been presented in this paper. It determines the ultimate...
Load and Resistance Factors for Bridge Design Code
The paper summarizes the code development procedures used for the new LRFD (load and resistance factor design) bridge code. The current specifications use allowable stresses and/or load...
LRFD Provisions for Wood Bridges
A project to develop a load and resistance factor design (LRFD) edition of the American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications for Highway...
Unified Code Provisions for Concrete Bridges
Provisions on limiting the flexural reinforcement adopted in the new AASHTO LRFD Specification for Bridge Design are summarized (1). They address minimum and maximum levels of reinforcement...
Design Guidelines for the Use of Debonded Strands
In this paper, presented are the flexural tests performed on beams containing debonded strands. Results show that debonded strands can be used reliably and safely, stipulating that the...
Development Length of Uncoated Prestressing Strand
The Federal Highway Administration is conducting ongoing research which investigates the development length of uncoated and epoxy coated prestressing strand in prestressed concrete members....
The Normandie Bridge
The Normandie Bridge will have one of the longest cable-stayed spans in the world, i.e. 856 m long. This paper briefly describes the design of the bridge, with the concrete access spans...
Construction of the Baytown Bridge, Houston
Connecting Baytown and LaPorte, the Baytown Bridge is a twin structure with four traffic lanes each. Its structure is designed as a cable-stayed bridge with concrete towers and composite...
