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...
Federal Public Works Infrastructure R&D
A New Perspective
Prepared by the Civil Engineering Research Foundation. This report provides an analysis of the federal role in public works infrastructure research...
Dynamic Response and Progressive Failure of Special Structures
This proceedings,
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....
In-Service Durability Evaluation of Armourstone
A summary flow diagram for rock evaluation, general to all rock types and engineering applications of rock is introduced. It is then applied to armourstone. Increasing detail within this...
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....
Roller Compacted Concrete Tailing Retention Dam
A roller compacted concrete (RCC) dam has been designed for gold tailing impoundment in southeast Alaska. To minimize up front capital costs, the curved gravity dam with multiple outlet...
Thermal Analysis for RCC?A Practical Approach
Roller compacted concrete (RCC) structures, by nature of the construction method, tend to be monolithic structures or structures with minimal contraction jointing. Recurring questions...
Thermal-Structural Analysis Methods for RCC Dams
Current procedures for evaluating temperature control and the placement of contraction joints in roller compacted concrete dams are not always evaluated with the aid of detailed analysis...

Robust Approach to Wave Runup Calculation
Wind wave runup on a natural beach is examined for the case of an irregular wave forcing function. A pragmatic approach to the calculation of the runup time series and the corresponding...
Application of Extremely Low Altitude Photogrammetry for Monitoring Coastal Structures
Extremely low altitude mapping photography exposed from a helicopter is showing considerable promise in providing another method of extending the many benefits of photogrammetric data...
A Case of the Shakes
New York City's unusual Terrace on the Park offers dining and dancing in a catered ballroom that stands six stories above the ground on four supercolumns. But when guests...
Peaches and Concrete
One Peachtree Center, Atlanta's latest highrise tower, will measure 62 stories high (860 ft) with 1.42 million sq ft of office space when completed next July. It will also...
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...
Passive Acoustic Emission for Quantitative Evaluation of Freeze Thaw and Alkali Aggregate Reaction in Concretes
Several experiments are reported in which the progression of freeze thaw (FT), alkali-aggregate reaction (AAR), and internal cracking caused by mechanical loading were monitored using...
Damage Assessment in Concrete Using Acoustic Emission
An acoustic emission (AE) is a localized rapid release of strain energy in a stressed material. This energy release causes stress waves to propagate through the specimen. These acoustic...
Study of Three Dimensional Crack Tip Location of Mortar by Acoustic Emission
Plain mortar specimens were tested under three-point bending. Experimental variables include the width of the specimen and the notch-to-depth ratio. The experimental results of 12 specimens...
Sonic NDE of Structural Concrete
Case histories are presented to illustrate applications of nondestructive evaluation (NDE) methods that use stress waves to characterize the conditions of concrete construction. The case...
