Design and Performance of Buried Fiberglass Pipes ? A New Perspective
The buried performance of fiberglass pipes was the subject of a comprehensive and multifaceted research program carried out in 1982 and 1983. Instrumentation, capable of accurately tracing...
Performance of Low Stiffness Plastic Pipe in Stiff Soils
Large diameter pipe made from ductile plastics, such as polyvinyl chloride (PVC), polypropylene (PP) and high density polyethylene (HDPE) can be effectively utilized in subsurface installations...
Design Criteria for Buried Flexible Pipe
A modified CANDE program was used to analyze a full factorial set of design parameters for buried, large diameter high density polyethylene profile-wall pipe. A new pipe subroutine was...
Importance of Pipe Soil Stiffness Ratio in Plastic Pipe Design
In this paper, the finite element method of analysis is used to study the effect of pipe-soil stiffness ratio on axial forces, bending moments, and deflection of pipes of varying stiffness....
The Present Status of Application of the Plastic Concepts in Structural Design
The different approaches of recognizing plastic behavior in the design of steel structures are reviewed and the design requirements that assure successful utilization of this behavior...
Computer-Automated Limit-States-Design of Steel Frameworks
The paper concerns the computer-automated synthesis of minimum-weight planar steel frameworks. For any number of applied loading cases, the design of the structure may be constrained by...
Plastic Design Requirements of the AISC Proposed LRFD Specification
The American Institute of Steel Construction proposed LRFD Specification (1) has recently completed a one year period of trial use and review. This paper discusses the background of the...
Abrasion Resistance of Polyethylene Dredge Pipe
In recent years there has been a slow but steady increase in the number of dredges using high density polyethylene (HDPE) pipe in discharge lines. HDPE's increased popularity...
Plastic and Other Limit State Methods for Design Evaluation
These proceedings consist of seven papers dealing with the topic of the design of complex structures using limit state methods. The emphasis is on the role of plastic or limit load techniques....
Pipeline Materials and Design
The proper use of pipeline materials and design is obviously paramount in the private and public works sectors. The introduction and proper use of new piping materials and design procedures...
Structural Plastics Design Manual
The structural behavior of plastics reflects a number of characteristics different from those of the metal, lumber, and concrete materials familiar to most design engineers. This manual...
Better Trained Construction Supers Would Boost Productivity
Everyone complains about poor productivity in construction. One way to improve it, says a recent Business Roundtable report, is to provide better training of first and second level supervisors....
Application of Plasticity and Generalized Stress-strain in Geotechnical Engineering
This volume on the application of plasticity and generalized stress-strain in geotechnical engineering is divided into two main sections, with an introduction on soil constitutive model...
Emerging High Performance Structural Plastic Technology
Structural plastics have forced their growth by better performance over conventional materials in hostile environments. Demand by industry for increased life of process equipment and structures...
Underground Plastic Pipe
Thirty-nine of the papers presented at the 1981 International Conference on Underground Plastic Pipe are included. The types of pipes examined include: thermoplastics, thermosetting plastic...
Design and Construction of World's Tallest Free-standing Fiberglass Stack
The design, fabrication and erection procedures are discussed for a 170-ft free-standing fiberglass reinforced plastic exhaust stack-scrubber system. Advantages and disadvantages in the...
Structural Plastics for the 80s
Engineers in non-civil fields have been using more and more light-weight, high-strength structural plastics and plastic composites every year, but civil engineers have barely begun to...
