Effect of Ocean Setback Standards on the Location of Permanent Structures
A measure of the degree of safety from long-term erosion can be estimated by comparing the actual distance an owner chooses to locate landward of the required setback with the estimated...

Hurricane Diana: Impact on Coastal Development
Hurricane Diana affected the coast of North Carolina during the period of September 11-14, 1984. Builders, designers, building officials and insurance adjusters responded to a written...

Engineering Surveying Manual
This manual is directed at the engineering manager who is responsible for planning and executing engineering projects which require the assistance of specialists in engineering surveying....

Staggered Truss Adapted to High Rise
The 34-floor Nashville Convention Center Hotel required a structural system that would overcome the tendency to vibrate in the wind. The solution was a modified staggered frame truss,...

Opportunity Knocks from Behind Bars
As more and more lawbreakers are put behind bars, more and more prisons are needed, so the opportunities for civil engineers are expanding. Three major types of construction are being...

Coping with Litigation
Engineers should learn legal philosophy, even though it seems unrelated to traditional technical practice. Monitoring changes in legal theory that may increase engineers'...

Building in Space
Work on the nation's first permanently manned space station has begun. Almost $200 million in contracts for conceptual design for the station were awarded by the National...

Get Involved with Cladding Design
Structural engineers should get involved with cladding design for their buildings. Including disclaimers for responsibility in the design contract will not prevent trouble or lawsuits,...

Tapping Deep Water Resources
Lena is the first commercial guyed tower. Its jacket is the longest ever fabricated, loaded out and launched in one piece. Lena stands in 1,000 ft deep water and has a three-level oil...

LAX Engineers Beat the Clock
Foreign and domestic crowds flying in for the Olympics were no problem for the Los Angeles Airport (LAX), thanks to the expansion and improvements completed a month earlier. LAX more than...

Bridging Twin Ports
The Major Richard I. Bong Memorial Bridge, part of U. S. Highway 2, connects harbors at Duluth, Minn. and Superior, Wisc. The new highway link was designed to relieve congestion on nearby...

Who Should Design Bridges?
For many years Design-Build-Proposals have been common practice in Europe (except in the UK). Structures in these countries are 20% more economical than similar projects in the U. S.,...

Construction-Induced Dynamic Pressure and Corresponding Impact Factors for Pipelines
The Bureau of Reclamation, U. S. Department of the Interior, conducted a study which measured pressure exerted by construction scrapers on a rigid, buried, instrumented concrete slab....

Influence of Depth-of-Cover on Pipe-Soil Interaction
A major research effort was undertaken to study the structural behavior of a natural gas pipeline under several critical service conditions. The program included a field test site near...

Investigations into the Structural Performance of Clay Pipes
Over the past 8 years, the Clay Pipe Development Association (CPDA) has commissioned non-destructive physical testing of vitrified clay pipelines. The diameters of the pipes have varied...

SPIDA: An Analysis and Design System for Buried Concrete Pipe
The paper presents a description of a new computerized direct design method for buried concrete pipe named SPIDA (Soil-Pipe Interaction Design and Analysis). Also the technical basis and...

Longitudinal Prestressed Piping for District Heating
The design of recently installed hot water district heating systems in the United States is based on similar systems developed in Europe. Longitudinal prestressing is used in the design...

Strains Induced by Combined Loading in Buried Pressurized Fiberglass Pipe
In 1983 Owens Corning Fiberglas and Utah State University collaborated on a study of combined strain behavior of fiberglass pipe to quantify the bending strain reduction as a function...

Buried Fiberglass Pipe Performance and Installation Requirements and Design Calculations in International Standardization
This paper elaborates on a proposed standard covering details of fiberglass pipe buried installation requirements and criteria for selection of pipe stiffness. It also discusses the selection...

Inspection/Condition Analyses of Large Underground Pipelines
Inspection/Condition Analyses of Underground Pipelines (sewers and conduits) will be a necessary function of the pipeline Owner/Operator. The Condition Analyses and Inspection phases are...
