Keeping Cables Calm
Cable vibration and corrosion are potential problems relating to cable-stayed bridges. Nonetheless, owners think their structural elegance is worth it, and increasingly longer cable-stayed...

Reliability and Uncertainty Analyses in Hydraulic Design
Prepared by the Subcommittee on Uncertainty and Reliability Analyses in Design of Hydraulic Structures of the Technical Committee on Probabilistic Approaches to Hydraulics of ASCE. ...

Can Engineers Cut Curtain-Wall Failures?
For many reasons, including owners' false perception of economy engineers have abdicated responsibility for curtainwall design. Failures of curtainwall components are very...

Arches For A Parkway
The final phase of construction on the Natchez Trace Parkway (which follows a centuries-old 450 mi trail between Natchez, Miss. and Nashville, Tenn.) is nearing completion almost 60 years...

A Dome To Remember
Under intense pressure from all sides, a trio of engineering and architectural firms working in San Antonio, Tex., turned the political coal of a stadium everyone wanted to build (but...

Dynamic Response and Progressive Failure of Special Structures
This proceedings, Dynamic Response and Progressive Failure of Special Structures, consists of papers presented in the two sessions of the First...

Calendar: Bridges 1994
Featured bridges are: Briggs Bridge (AK); Stone Arch Bridge (NY); Rio Grande Gorge Bridge (NM); Bridge Street Bridge (MI); Hennepin Avenue Bridge (MN); Egypt Pike Bridge (OH); William...

Elected Officials
Schools and organizations train engineers to use facts. But, engineers are often content to base decisions on their opinions. While engineering judgment is an important part of the professional...

Appendix B: Ten Primary Reasons for Failure in Negotiation
Back matter pages come after the papers or chapters in a published work. This back matter contains ten primary reasons for failure in negotiation....

Physical Model Testing of Broken Armor Stone
Cracking, breaking into two or more pieces, flaking, crumbling, and abrading may reduce an armor stone to a size where wave action can remove it from the structure causing a local instability....

Principles of Holistic Medicine Applied to Infrastructure Maintenance: A Test Case
A humorous consideration of the question of whether holistic medicine�that is, the treatment of the entire physical and emotional configuration of the patient instead of the solely medical...

Learning to Love NDT
Sometimes overblown claims and the practical limitations of early nondestructive tests for concrete have left many civil engineers leery of NDT methods. While some are aware that NDT has...

Investigation of Coastal Conditions at Oregon Inlet, NC for the Replacement of the Herbert C. Bonner Bridge
The Bonner Bridge across Oregon Inlet was constructed in 1962 and is approaching the end of its service life. Planning for a future crossing must consider natural inlet migration expected...

L'Ambiance Plaza: What Have We Learned
In April 1987, a structure called L'Ambiance Plaza collapsed during construction, killing 28 workers. The building, in Bridgeport, Conn., was being built using the lift-slab...

Engineering a Monument, Evoking a Nightmare
Rather than simply standing as a backdrop for exhibits, the $53.2 million U.S. Holocaust Memorial Museum is intended to be part of the fabric of the exhibition itself. Now under construction...

Concrete Beam Testing with Optical Fiber Sensors
The use of an embedded multimode optical fiber to monitor curing and load-to-failure testing of a reinforced concrete beam has been investigated. The embedding process used to network...

Evaluation of Concrete Bridges by Impact-Echo
Strength of post-tensioned bridge structural members primarily depends on the tensile capacity of their post-tensioning steel reinforcement. To prevent corrosion, the post-tensioning steel...

A Critique of the Ultrasonic Pulse Velocity Method for Testing Concrete
The pulse velocity method is the most widely used ultrasonic nondestructive method for assessing concrete quality. However, it has been well established that the relation between ultrasonic...

Nondestructive and Destructive Testing of a Three Span Skewed R. C. Slab Bridge
A three span, skewed, reinforced concrete slab bridge was field tested to destruction by the authors. Before the actual destructive test, nondestructive tests were performed to determine...

Safeguarding Steel
U.S. bridges are caught in the money squeeze. Painting has become a luxury few public agencies can afford and complying with EPA regulations has escalated costs even more. The paint/coatings...
