Strategies for Bridge Inspection Using Probabilistic Models
This paper describes the application of probability analyses in planning an inspection program for highway bridges. When damage in the form of fracture and cracking is the major concern,...
Reliability Assessment and Reliability-Based Rating of Existing Road Bridges
A practical reliability model for the safety assessment and rating of existing R.C. bridges are developed by explicitly incorporating the degree of deterioration and damages based on available...
The Prefab Tunnel
Jacking a prefabricated concrete arch through a railroad embankment to provide a new access ramp to the Don Valley Parkway in Toronto was done for the first time in North America. In September...
Buried Structural Capacity of Insituform?
In July 1988, a test was conducted at Utah State University to determine the structural support that can be provided to a failing rigid pipe system through the use of the Insituform process....
Investigation & Rehabilitation of Seattle's Tolt Pipeline
Seattle Water Department's Tolt Pipeline brings water 24 miles from storage in the Cascade Mountains into city and suburban distribution systems. Twenty-three miles of this...
In-Situ Evaluation of 30-In. (762-mm) Diameter Prestressed Concrete Lined-Cylinder Pipeline
The results of an extensive investigation to evaluate the in-service condition and future serviceability of an existing lake water make-up pipeline are briefly described herein. The pipeline...
Performance of Pipe Spillways for Dams
The Soil Conservation Service has used several different kinds of pipe products for spillway conduits of dams. Materials with a shorter estimated life are used for smaller low hazard dams...
Dynamics of Composite Tubes
A displacement-based stiffness method is used to study the characteristics of dispersive wave propagation in laminated composite cylindrical tubes. It is assumed that the tube is composed...
Design Considerations for a Ceramic Fabric Radiator
The design of an Advanced Ceramic Fabric (ACF) thermal management device for use in both interplanetary and near-earth space must consider several important aspects of the environment....
Creede, Colorado?Channel Rehabilitation
The existing grouted stone channel in Creede, Colorado, is approaching the end of its useful life. The channel is subjected to repeated freeze-thaw cycles causing spalling of the grout...
Concrete Pipe Trenchless Technology
Precast reinforced concrete pipe is the most commonly used pipe material for jacking operations. For over 90 years, concrete pipe techniques, procedures and applications established the...
The Great American Pyramid
For more than 50 years officials of Memphis, Tenn. have wanted to establish a link to their Egyptian namesake--and they will, through a pyramid. As opposed to its Egyptian forerunners,...
Stabilization of an Alluvial Channel in an Urbanized Area
Grade stabilization structures have been used for many years to control degradation of alluvial stream in the southwest. These structures result in reducing the gradient of the stream...
Overtopping Protection for Embankment Dams
Modifications that allow safe overtopping during large flood events can be made to existing embankment dams. These modifications are on the leading edge of technology and require special...
Structural FRP Composites
Fiber-reinforced plastics are only just being discovered by civil engineers. Long used in expensive military and aerospace applications, they are beginning to find their way into structures....
OTEC Seawater Pipe Cost Comparisons
Describes a material which can substantially reduce the cost of seawater pipes and two methods for building and deploying such pipes for use in land-based OTEC installations, outfall sewers,...
Structural Wood Products
This paper provides a description of available structural wood products. Traditional products such as lumber and plywood are being supplemented by new products that include composite lumber...
Bond Strength of Epoxy-Coated Reinforcement to Concrete?An Update
The results of a large-scale study to determine the effect of epoxy coating on bond strength is described. The study addresses the effects of coating thickness, deformation pattern, bar...
Influence of Epoxy Coating on Stress Transfer from Steel to Concrete
To assess the influence of epoxy coating on the bond characteristics of reinforcing bars, a series of tests was conducted to determine differences in stress transfer between coated and...
Evaluation of Bond Performance of Epoxy-Coated Reinforcing Steel Using Nonlinear Finite Element Analysis
The role played by epoxy coatings on the failure of standard beam-end specimens is explored. The specimen consists of a reinforcing bar embedded in concrete. As the bar is loaded, the...
