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...

Seismic Behavior of Type PR Steel Frames
Type PR(partially restrained 'simple framing') is one of the methods of design specified in the AISC LRFD(1986) Design code for the design of unbraced steel building frames. In this method...

Assessment and Upgrade of an Older Transmission Line
This paper discusses the various tools and procedures which have been used to assess and upgrade an older 130 kv tower line. The purpose of the assessment was to determine the line compliance...

ASCE GUIDE for Design of Guyed Transmission Structures
This paper describes the contents of a new ASCE guide for the selection and design of guyed electrical transmission structures. Guyed transmission structures present unique analysis and...

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 Clark Cable-Stayed Bridge at Alton, Illinois
The Clark Cable-Stayed Bridge crosses the Mississippi River at Alton, Illinois. The successful bid by McCarthy Bros/Clark Bridge JV was for the steel alternative. The bridge design included...

The Tatara Bridge - World's Longest Cable-Stayed Span
The Tatara Bridge now under construction has the main span length of 890m which will be the world's longest in cable-stayed bridges when completed. Except for certain lengths of prestressed...

Externally Stiffened I-Beam to Box-Column Connections
This paper is concerned with I-beam to Box-column connections stiffened externally. Experimental and theoretical findings on full-scale connection models are highlighted. The performance...

Investigating the Behavior of a Lattice Structural Section
Tests were conducted on a fully instrumented lattice section assembled using various connection types (bolted or welded). The results of this study show that bolt slippage can have a major...

Creep Analysis of Composite Steel-Concrete Members with Deformable Connectors
The long-term analysis of composite steel-concrete beams with elastically deformable connectors is presented. The basic integro-differential equation governing the problem is solved by...

Uniform Lateral Load Capacity of Infilled Frames
Three tests were conducted on 2.4 meter by 2.4 meter steel frames infilled with structural clay tile to determine the behavior and capacity when subjected to uniform lateral loads. An...

A Peice-wise Linear Evaluation of Masonry Infills Subjected to Out-of-plane Seiesmic Drift
This paper summarizes the out-of-plane testing and analytical modeling of a full-scale unreinforced masonry (URM) infilled frame and a bare frame without infilling. The testing was part...
