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...
Analysis and Design of SFRC Structural Elements
This paper presents and validates practical methods for flexural, shear and torsional analysis and design of fibrous reinforced concrete structural elements. The effects of both fiber...
Steel Fiber Reinforcement in Structural Application
Ribbon Technology Corporation's use of steel fiber reinforced concrete in the construction of their new manufacturing and office facility in Gahanna, Ohio. Cost savings are obtained by...
The Use of Built-Up Compression Members?A Fabricator's Viewpoint
A variety of cross-sections of built-up compression members that have been used are shown. Suggested items that need to be addressed for the successful design and fabrication are discussed....
Built-Up Compression Members for Noval Structural Systems
This paper discusses built-up compression members used in novel structural systems for two high-rise buildings: InterFirst Plaza at Dallas Main Center and Columbus Center in New York....
Design of Built Up Compression Members for Long Span Bridge Structures
This paper discusses the design of built up compression members for long span bridge structures including trusses and arches. Provisions of load factor design and use of high strength...
QST Rolled Shapes, a New Generation of HSLA Compression Members
With the development of the Quenching and Self-Tempering (QST) process by the Luxembourg steelmaker ARBED S.A., a new generation of High Strength Low Alloy (HSLA) rolled shapes has become...
Creep and Shrinkage of Composite Columns in Tall Buildings
The simultaneous presence of steel and composite columns in tall buildings is a common occurrence. The axial shortening characteristics of composite columns are influenced by creep and...
Performance and Serviceability of Composite Floors
Concrete slabs on steel deck are the most common type of floor system in use today. This system of construction is particularly advantageous when ultimate strength design (LRFD) is used....
Achieving Level Composite Steel Floors
Constructing deflected composite steel floors that are level is a complex operation, and one which requires cooperation and an exchange of information between the structural engineer and...
Vibration and Impact in Skewed Steel Bridges
The vibration and impact of skewed multigirder bridges due to vehicles moving across rough bridge deck are studied. The bridges are modeled as grillage beam systems. The vehicle is simulated...
Magnetic Flux Leakage for Bridge Inspection
For many years the Federal Highway Administration and before that the Bureau of Public Roads had focused its nondestructive evaluation program on development of better tools to inspect...
Remote Monitoring of a Stressed Timber Bridge Deck
The long term behavior of a CCA treated stressed timber deck bridge is being monitored, at present, using a remote data acquisition system. The bridge which is located in Gray, Maine was...
Full Scale Dynamic Monitoring of Highway Bridges
Sensitivity of identified modal properties by physical testing is critical for automated monitoring of bridge structural condition. It is investigated here considering flexure modes and...
What is Optimization?
Basic concepts of optimization are described using design of a plate girder as an example. First, a way to formulate the problem as an optimization problem is presented. Then basic terminologies...
How to Optimize Steel Frameworks
This paper presents the details of a design synthesis strategy to conduct computer-automated design of least-weight structural steel frameworks, where members are automatically sized using...
Steel Fiber Reinforced Shotcrete?An End-User Prospective
Nearly 15 years of experience demonstrates that steel reinforcing fibers in shotcrete offer considerable advantages to all end-users: designers, contractors and owners. These include demonstrable...
