Pavement Design Considerations for Heavy Aircraft Loading at BAA Airports
BAA operates seven airports in the United Kingdom. Two of them, Heathrow and Gatwick, handled 61 million passengers in 1991 with 543,000 air transport movements, 25% by wide-bodied aircraft....
Ft. Campbell Airfield Emergency Reconstruction
The air deployment from Fort Campbell, Kentucky to Saudi Arabia in support of Operation Desert Storm in the summer and fall of 1990 involved several hundred C5 and C141 aircraft loaded...
Fracture Mechanics
This brief report, prepared by ACl 447 Subcommittee 2, reviews recent advances in finite element modeling of fracture and damage in concrete structures. The fundamentals of the fracture...
Computational Aspects
In the past, two distinctly different approaches - smeared and discrete failure models have been adopted to describe failure mechanisms in plain and reinforced concrete structures. Although...
Finite-Element Analysis as a Design Tool
This chapter covers the role of finite-element analysis in professional structural design. Past and present usage is covered lightly, with practice in a reputed design office as example....
Structural Fire Resistance Design of Wood Beams and Columns: A Comparison of European and North American Practices
North American and Eurocode design methods for fire-resistive exposed wood members provide a very good example of the translation of research into practical engineering design procedures....
Execution and Evaluation of High Capacity Caisson Load Tests in Glacial Deposits
As part of the Boston Harbor clean up project, the new 1,000 mgd Deer Island Sewerage treatment plant includes ten 240 feet high egg-shaped 'residuals' tanks. Contract documents called...
Bi-Directional Load Testing of Shafts to 6000 Tons
This paper describes the use of Osterberg cells (O-cells) to perform bi-directional load testing on full size production drilled shafts for a major bridge foundation near Owensboro, Kentucky....
A Laboratory Procedure for Partial-Wetting Collapse Determination
Partial wetting results in partial collapse, which is linked to the reduction in soil suction caused by wetting. The laboratory procedure presented in this paper represents a modification...
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...
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....
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....
Tomorrow's Schools
While what's wrong with education looms as a national concern, many communities are doing something positive about it. They're constructing new schools designed...
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...
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...
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...
Behaviour of Prestressed Concrete End Blocks
This paper briefly reports on a series of experiments carried out on strip-loaded prestressed concrete end blocks. The results show that corresponding design methods presently used in...
