Acoustic emission technique (AE) was used to investigate fatigue cracking phenomenon during a series of laboratory tests of various bridge steels and during field testing of an in-service...
Nondestructive Inspection of Steel Bridge Members
Assessment of the conditions of an aging population of bridges in order to determine the proper maintenance or retrofit operation is a challenge of great importance to bridge engineers...
After-Fracture Response of a Two-Girder Steel Bridge
The I-40 bridges over the Rio Grande are due to be razed in mid 1993 due to geometry and traffic safety considerations. The bridges are classified as 'fracture critical' two girder steel...
Modal Analysis Technique for Bridge Damage Detection
The dynamic responses of a wide-flange steel beam with artificially introduced cracks were studied analytically and experimentally. Frequencies, displacement mode shapes (DMS) and strain...

Ductility Analysis of Overload and Settlement
The concept of sufficient ductility to avoid premature or brittle failures is gaining wide acceptance in structural engineering and is an important aspect in mitigating the consequences...
An Innovative Connection Detail for High-Rise Buildings
Composite columns consisting of hollow steel tubes filled with high strength concrete have been used in high rise building construction in the USA and Far East Asian countries. The focus...
Seismic Design of Steel Beam-to-Box Column Connections
This paper is a study of the ductility requirements of steel beam-to-box column connections using the bolted beam web and welded beam flange details. Since the beam moment at the connection...
Recent Successes in Welding Jumbo Shapes
A rather unique structure utilizing jumbo shapes was recently designed and fabricated. The structure was 100% welded according to the specifications for welding jumbo shapes recently developed...
Design of Monosymmetric Sections in Flexure
Monosymmetric members are generally I-shaped, symmetrical about the plane of the web, and characteristically have a larger compression flange than tension flange. Examples are crane girders...
Inelastic Behavior of Noncompact Steel Bridge Girders
This paper highlights the results from one of several finite element studies of the inelastic moment-rotation behavior of continuous-span non-compact bridge girders at interior-pier locations....
Composite Beams and Joists
Composite beams and joists used as flexural members in multistory steel-frame buildings are considered. Research results have shown that present design values for headed shear studs, used...
Interaction Between Beam and Steel Connections
The overall objective of the investigation is to study the behavior of a particular steel connection type, flush end plate steel connections, subjected to shear, axial forces, and possibly...
Seismic Resistance of Steel Fiber Reinforced Concrete Beam-Column Joints
This paper discusses the advantages of using steel fibers in seismic resistant beam-column connections. First, the effects of fibers on the various aspects of behavior of concrete are...
