A New Laboratory for Teaching Structural Engineering
A new, practical, computer-assisted laboratory, 'AN/EX,' has been developed for teaching structural engineering. Specifically, AN/EX has been developed to encourage cross-verification...
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...
Local Web Crippling of Unstiffened Multi-Cell Box Sections
Full-scale experiments and analyses show that the AISC/LRFD design equations for web yielding and web crippling strength of unstiffened webs, developed from test data on I sections, can...
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 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...
SemiActive Structural Control: A Low Cost Fix for An Infrastructure at Risk
There is increasing societal pressure on the engineering profession to develop cost effective methods to extend the service life of the civil infrastructure. While the degradation of the...
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...
Progress in Reinforced Concrete Column Design
This paper reviews some of the design procedures used for both braced and unbraced frames constructed in reinforced concrete. The discussion refers to the problems of material and geometric...
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...
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...
