Bridge Rail Impact Forcing Functions
Bridge rails are designed according to AASHTO standards with a static 10-kip (44.5 kN) lateral load. The computer programs BARRIER VII and COSMOS are used to determine the deflections...

Cumulative Impact of Heavy Permit-Trucks on Steel Bridges
In many parts of North America, special permits are issued to heavy vehicles without considering their cumulative effect on steel bridge components. Such overloads may initiate crack propagation...

Corrosion Resistant Epoxy-Coated Reinforcing Steel
Research conducted in the 1970s to evaluate and develop criteria for nonmetallic coatings to protect steel reinforcing bars embedded in concrete bridge decks from the corrosive action...

Application of Concrete-Filled Steel Tubular Columns in Tall Buildings in Earthquake Area
In this paper an outline is given of the background, the design concept, structural features, construction and economy of the concrete-filled steel tubular coumns of tall buildings in...

One Peachtree Center: Atlanta Georgia
Presented in this paper are the architectural and structural concepts of One Peachtree Center built in the city of Atlanta. This 62-story tall building has changed the downtown skyline...

One Ninety One Peachtree and NationsBank: Composite Additions to the Atlanta Skyline
The structural design of two composite buildings in Atlanta is described in this paper. A composite exterior partial tube was used in one case and a composite super-column system was utilized...

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...

Steel Compression Member Design in the 1994 Canadian Standard
The 1994 edition of CSA Standard S 16.1-M94, Limit states design of steel structures (CSA 1994) contains explicit methods for computing the compressive resistance of monosymmetric and...

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...

Moment-Rotation Behavior of Pultruded Beam-to-Column Connections
Presented are experimental details and results of five tests carried out to study the moment-rotation behavior of flange cleated connections for frames of pultruded members. The full-sized...

Progress in Reinforced Concrete Column Design: An Introduction
The Joint ASCE-ACI Committee 441 on Reinforced Concrete Columns is investigating a number of problems related to structural behavior and design of reinforced concrete columns. This paper...

Design of Lateral Steel in Columns
Lateral steel in columns is generally required for shear resistance, confinement of concrete and prevention of buckling of longitudinal bars. This paper is limited to the design of lateral...
