Use of Private Legal Actions to Protect Beaches
In response to shoreline migration, private oceanfront landowners often erect shoreline erosion control structures such as groins and bulkheads. These structures may exacerbate erosion...
Vanishing Beaches: Erosion Control & Public Policy
Currents, often remotely situated, divert the littoral supply which normally ensures a positive balance among factors preserving natural beach configurations. Artificial structures such...
The Redevelopment of Fisherman's Wharf, San Francisco, California
The San Francisco Port Commission is desirous to upgrade the wharf area to revitalize the fishing fleet. The key element for such redevelopment would be a breakwater to protect the berthing...
Coral Reef Modeling: Key Largo Case Study
A numerical model called CORALSIM has been developed for the Key Largo Coral Reef National Marine Sanctuary in the Florida Keys. The model was developed as a management tool to study the...
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...
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...
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....
Effect of Shallow Trench Construction on Cast Iron Pipelines
This paper summarizes the results of three-dimensional finite element analyses to evaluate the strains and displacements sustained by 4, 6, and 8-in. (100, 150, and 200 mm)-diameter cast...
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...
Simplified Stress and Deformation Analysis for Pipeline Construction
This paper discusses the strength and deformation behavior of flexible steel pipes during pipeline construction. Some possible simple and quick solutions to these special design and construction...
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...
