Double Diamonds: New Brand for a Texas Bridge
Double diamond towers, distinctive as a cattle brand but tall as a 44 story building, have reached landmark status on the Texas Gulf Coast even though the bridge they will carry won't...
Bayesian Reliability Updating of Existing Steel Girder Bridges
Bayesian statistics is used to update the reliability of existing composite steel girder bridges. A 60 ft. long simply supported superstructure is considered. The reliability for the ultimate...
Anatomy of the Loma Prieta Earthquake Records of Two Steel Buildings Using MIMO System Identification
The Loma Prieta strong-motion records of a 4-story and a 47-story steel building are analyzed using system identification. A time variation study from the 4-story building records reveals...
Scattering of Waves by Steel Reinforcement in Concrete
The application of wave-sensing methods to the non-destructive evaluation of concrete structures requires often the use of simple (or at least tractable) models for the solution of the...
Stability of Beams in Eccentrically Braced Frames
As the link yields and strain hardens in an eccentrically braced frame, the beam segment-outside of the link is subject to a combination of high axial force and bending moment. For certain...
Locally Buckled Plastic Hinge Behavior Under Monotonic and Cyclic Loading Condition
In order to clarify the influences of local buckling under monotonic and cyclic loading conditions, experimental studies were carried out on W8x10 A-36 structural steel members subjected...
Design Codes for Lunar Structures
The American Institute of Steel Construction (AISC) Manual of Steel Construction is a codification for the design and construction of steel structures. It includes information, some tabular...
The Design of a Permanent Lunar Research Station
The advancement of the United States efforts in space exploration and research requires the establishment of a permanent manned lunar research station. This paper explores the possible...
Denver International Airport Fabric Roof Design
The design of Denver's Landside Terminal Complex for the new Denver International Airport, called for some far reaching vision coupled with imaginative building technologies. Because of...
Microbiologically Induced Corrosion
Researchers investigating a building whose columns bled a colorless liquid found that the building was under attack by microorganisms. A community of bacteria had contaminated the fireproofing...
Fiber: Good For the Concrete Diet?
Fiber reinforcement of concrete has many advantages, but after thirty years of research those benefits have most often been seen in a laboratory. Some materials, such as synthetic fibers,...
Probabilistic Analysis of Post-Tensioned Steel Girder Bridges
External post-tensioning is used as a means of strengthening existing steel girder bridges. Since absolute safety of structures is impossible to attain due to uncertainty in load and resistance,...
A Unified Simulation Approach to Structural System Reliability Analysis
To determine accurate estimates for the system reliability of large complex structures requires considerable computation; unless the problem is assessed in an efficient manner the analysis...
Incorporating Corrosion in Reliability-Based Design of Anchored Bulkheads
Corrosion of steel is an important factor in the design of marine structures. A reliability analysis of anchored bulkheads showed that corrosion changes the critical failure mode from...
A Fatigue Reliability Model for Railway Bridges
A fatigue reliability model is described for safety evaluation of steel railway bridges. The model is a function of six independent random variables and can accommodate different types...
Low-Cycle Fatigue Prediction for Ramberg-Osgood Type Materials
The prediction of low-cycle fatigue crack growth is successfully made by an equation employing the J-integral range. This equation, originally proposed by Dowling and Begley, is analogous...
A Systems Reliability Approach to the Safety of Steel Connections
A methodology is presented to determine the probability of failure of steel connections using a systems approach. Results indicate that connection safety evaluations which do not use this...
Metrication of Construction?A Message to the American Society of Civil Engineers
The author discusses the reasons for metrication of the U.S. construction industry, describes the Canadian experience in this area, and outlines the necessary steps to alleviate the metrication...
Design of Latticed Steel Transmission Structures
This standard,
Seismic Rehabilitation of Seattle's Pier 69
The Port of Seattle, one of the largest on the west coast of North America, made a strong statement regarding their support for reusing existing structures when a decision was made to...
