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...
Analysis of the Seismic Records of a Suspension Bridge
A well-instrumented suspension bridge in Los Angeles, was shaken by the October 1, 1987 Whittier earthquake (ML = 5.9). This study addresses the...
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...
Ambient Vibration Response of a Long Span Bridge
Natural frequencies, mode shapes and damping characteristics for a long-span cable-stayed bridge were experimentally determined from a series of ambient vibration tests for both the cantilever...
Instrumentation Considerations for Nondestructive and Destructive Testing of Reinforced Concrete Slab Bridges
This paper examines the process of selection and calibration for instruments used in nondestructive and destructive field tests of a reinforced concrete slab bridge. Of great importance...
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...
Performance Monitoring of Concrete Structures with Embedded Sensors
This paper describes the use of embedded fiber optic sensors to monitor the performance of reinforced concrete structures. The fiber optic sensors are capable of measuring vibrations,...
Monitoring Performance of Full Scale Structures
General Physics Services Corporation (GPSC) of Columbia, Maryland has developed a device for the remote long-term monitoring of full scale structures, such as highway bridges. This patented...
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...
Coolidge Dam Abutment Stability and Stabilization
This paper focuses on left abutment stability assessments and stabilization measures at Coolidge Dam, Arizona. Initial assessment of abutment stability was based on limited rock strength...
