World's First Iron Bridge
In 1779, using a new man-made material, skilled English workmen built a single-span bridge of cast iron over a steep river gorge about 140 miles northwest of London. The result was a 424-ton...
Current Trends in Design and Construction of Embankment Dams
This report is concerned primarily with the embankment itself although foundation and abutment treatment are considered essential elements of the embankment. It covers a broad range of...
Guide to Investigation of Structural Failures
This guide contains a broad range of instructions and suggestions regarding structural failures. Topics include failure causes by project type, failure causes by structural type, failure...
Behavioral Factors in Selection of Technologies
Where a well-known technology is provided to a population that has long been acquainted with its use, the problems of predicting patterns of social behavior are relatively simple. The...
Epoxies � Miracle Materials Don't Always Give Miracle Results
In civil engineering applications, in the past 15 years epoxies have become widely used and have given excellent performance in floor surfacing, corrosion protection, repair of cracked...
$70 Million for Dam Inspection
In 1972, Congress passed the National Dam Inspection Act, requiring the U.S. Corps of Engineers to inspect and inventory all dams in the United States; but few dams were inspected. Then...
EPA Proposes Far-Reaching Regulations for Reducing Synthetic Organics in Drinking Water
In late January, 1978, EPA proposed far-reaching regulations for reducing synthetic organic chemicals in drinking water, bringing about the most sweeping changes in the water-treatment...
Major Cause of Earthquake Damage is Ground Failure
Ground failure is one of the most destructive effects of large earthquakes. For example, about 60% of the damage during the 1964 Alaska earthquake was a consequence of ground failure....
Fatigue Cracking�Problem for Welded Steel Bridges
A recent problem with welded steel bridges is fatigue cracking at welded details. Fatigue cracks begin in small flaws or discontinuities at welded connections and grow to a critical size...
Rouen, France Water Treatment Plant Using Biological Activated Carbon
The la Chapelle drinking water treatment plant in Rouen, France was designed specifically to incorporate biological activated carbon (BAC). With many U.S. cities faced with the prospect...
Counteracting Chloride-Induced Damage to Bridge Decks with Latex and Plastic
Salt used to control ice causes deterioration of reinforced concrete bridge decks, but recent developments, though still somewhat expensive, can prevent deterioration of existing decks....
Coastal Controversies Abound at Record-Breaking Conclave
Coastal Zone '78 was the largest specialty conference ever held by the ASCE, drawing over 1,000 participants from a wide spectrum of professions that are involved in coastal...
Newark Airport Pilots Cost-Saving Runway Paving Concept
The NYC Met Section nominee for the 1978 Outstanding Civil Engineering Achievement Award was the expansion of Newark International Airport. The $200 million redevelopment included a new...
Rx for Drought: Pumping Plant to the Rescue
Designed and built by the East Bay Municipal District, the pumping plant built last year at Middle River, Calif. was not unusual in design. What was unusual was the speed with which it...
Reef Runway is First in Airport Design
The Reef Runway Project of Honolulu International Airport constructed on a coral reef, provides approximately 765 acres of new land for the 12,000-ft-long runway with its associated taxiways...
Germany, Belgium and Los Angeles have Mandatory Design Review for Major Structures
The report of the engineering investigation into the causes of the collapse of the Hartford Coliseum space truss cited design deficiencies as the cause of failure. That report also says...
Reliable Structural Weldments for Critical Service
Fracture control plans are considered in light of weldment rather than base material alone. Data are presented on the probability of base materials (i.e., plate) having adequate toughness...
Coping with City Shrinkage
Sooner or later, many of the older cities of the U.S. are going to have to face up to the fact their population and economic bases are shrinking. Many cities continue to display an easy...
Single Additive for Recycling Asphalt Pavements
A design concept for recycling deteriorated asphalt pavements using a single reclaiming agent has been developed. The article established guidelines to help engineers determine the physical...
Geotechnical Practice for Disposal of Solid Waste Materials
The papers for this conference are grouped under the themes of four of the general sessions: 1) Geotechnical properties affecting disposal and utilization; 2) utilization in dams, embankments,...
