Wind Hazards Reduction Program
The 1990's mark the International Decade for Natural Disaster Reduction. In this context, the Wind Effects Committee of the Structural Division strongly endorses the establishment of a...
Mitigation of Wind-Created Risks During Construction
Wind damage to structures during construction has been found to be significant and often catastrophic. Structural failures are often the result of wind loads that are far less than the...
Investigation of Full-Scale Performance of Structures?Research Potentials
It is well known that actual, or true, behavior of completed structures does not necessarily conform to often simplified analysis predictions. This may be due to any of several reasons...
Behavior of Horizontally Curved Steel Highway Bridges
Horizontally curved highway bridges represent up to 25 percent of the market for new steel-bridge construction each year. However, unanswered questions remain concerning the fundamental...
Bridge Management Research Needs
The present article deals with some aspects of bridge management of particular interest to bridge engineers and to bridge users at the moment. It addresses questions such as life-cycle...
Seismic Strengthening for Structures in Regions of Low Seismicity
Most existing structures were not designed to today's seismic codes and standards, and in fact in low seismicity regions codes did not require seismic design until recently....
Long Life Fatigue Behavior of Welded Steel-Bridge Girder Details
The Federal Highway Administration is nearing completion of a five year, 1.5 million dollar effort titled 'Variable Amplitude Load Fatigue' to investigate the behavior of welded bridge...
Steel Alternates for the Hoover Dam Bridge
As input to the Environmental Impact Statement studies of appropriate long span bridges were performed for three alternate corridors across the Colorado River near Hoover Dam. Details...
Durability of Concrete Bridges in Virginia
This paper discusses four major types of deterioration found in concrete bridges: corrosion of the reinforcement, alkali-aggregate reactivity, freeze-thaw deterioration, and attack by...
Bonded Polyester Concrete Overlays Used in California
Bonded polyester concrete overlays have been very successful in California in restoring and preserving bridge decks from damage by road salts. The polyester concrete system has been employed...
Bridge Engineering and Life Cycle Cost
The Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) requires that all Federal Aid projects must 'consider...the use of life-cycle costs in the design and engineering of...
A Shear Transfer Model for Floor-To-Wall Connections in Concrete Masonry Structures
Based upon experiments conducted at the Univ of California, San Diego (UCSD) on floor-to-wall connections in concrete masonry structures, a constitutive model was developed for the overall...
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...
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...
An Overview of the Potential Applications of Neural Networks in Civil Engineering
Neural networks are computational models inspired by the structure and operation of the brain. They are massively parallel systems, made up of a large number of highly interconnected,...
A Prototype Expert System for Rapid Visual Screening of Seismically Hazardous Buildings in California
A rapid visual screening expert system, California Rapid Building Seismic Evaluation Expert, was developed to enable efficient and effective identification of seismically hazardous buildings...
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....
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...
