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...
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...
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...
Harmonization of Reliability-Based Timber Engineering Codes and Standards
An overview of activities related to harmonization of reliability-based timber design codes and standards is presented. The overview is based on information generated through a NATO Advanced...
The Canadian Approach in the Design of Wood Structures: Conversion to Limit States Design
During the early 70's, the National Building Code of Canada (NBCC) established the principle that structural design be carried out using the limit states design (LSD) method. The technical...
Strength Variability of Wood Formwork Members
Failure of concrete formwork is one of the main causes of concrete construction failures. Among the main causes of formwork failure is inadequate strength. Currently there is no published...
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...
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...
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...
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...
