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...

U.S. / Japan Large Scale Cooperative Research Program for Steel Structures
The US/Japan Cooperative Research Program Utilizing Large Scale Test Facilities for Earthquake Resistant Design was initiated in 1980 using a combination of full-scale, small-scale, subassemblage...

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...

First Bank Place: A Composite Cruciform Spine
The First Bank Place, designed by the internationally known architectural firm of Pei Cobb Freed and Partners, is a granite-clad, 56 stories tall building in downtown Minneapolis. Presented...

Composite Walls as Shear Elements in Tall Structures
This paper describes a system of composite walling that can be used as a lateral load resisting system in tall structures. The composite walling comprises two skins of profiled steel sheeting...

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...

Lateral Bracing Criteria of the Composite Braces
In order to simplify the hysteretic characteristics of diagonal steel braces, a lateral bracing problem of unbonded braces embedded in the concrete panel is treated here. Lateral bracing...

Recent Developments in Seismic Response of Composite Structures
Lack of sufficient data has limited a wider application of structures using mixed steel-concrete construction in seismically active regions. This paper summarizes some recent studies at...

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...

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...

Strut-Tie Model Design of Disturbed Regions in Concrete Structures
The design of disturbed (highly non-linear behavior) regions in concrete structures is illustrated using strut-tie approach. The use of this approach assisted with interactive computer...

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...

Multimedia Technology and Structural Steel Design
A project is underway at The Pennsylvania State University to produce Steel Design Educational Module (SteelDEM) software. This intelligent tutor and teaching aid utilizes the state-of-the-art...

Lateral Buckling: A Comparison of AISC-LRFD and Eurocode 3
The nominal moment capacity of laterally unsupported, doubly-symmetric, steel I-beams are computed and compared using the AISC-LRFD and EC 3 design recommendations. A review of the EC...

Innovative Design of Steel Gable Frames
Common wisdom holds that conventionally designed gable frames fabricated from rolled sections cannot compete with metal building system frames fabricated from plate and bar stock, from...

Evaluation of Corroded Steel Chimneys
The paper is focused on the analysis of corroded steel chimneys. Cylindrical steel plates are exposed to thermal and chemical effects. The study is based on the results of extensive measurements...

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...

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...

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...

Rational Limits for Longitudinal Steel in Concrete Columns
Current limits for the amount of longitudinal reinforcement in concrete columns were established more than 60 years ago. Commercial grades of reinforcement in 1930 were about half as strong...
