Reliability Consistent Load and Resistance Factors
A practical algorithm to find the partial safety factors consistent with target reliability in LRFD format is proposed. The method is based on Second Order Second Moment method and Reliability...
Rethinking Flood Control Channel Design
Until recently, the standard method of flood control was channelization�converting a natural stream to a uniform channel cross section. But this single objective approach is coming under...
A Doubling Design: Rochester's Expanding Airport
Few projects offer greater design challenges or pose more critical construction complexities than a new air passenger terminal, especially when that new terminal must be built on land...
Industrial Strength 3-D

Advances in Pipeline Materials and Design in Europe and North America
This paper presents an overview of various developments in materials technology and design procedures in the Western Hemisphere over the last 20 years. Some projections for anticipated...
Evaluating Thermal Pressure Changes in Liquid Packed Piping
Theoretical and practical issues involved with the phenomenon of thermally induced pressure change in closed piping systems are investigated. The mathematical derivation of the applicable...
The NOVA SPAN Bridge System
The NOVA SPAN Bridge concept provides the basis for the design and construction of a new variant in the field of bridges and culverts which, in its performance and operation, incorporates...
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....
Short-Term Versus Long-Term Pipe Ring Stiffness in the Design of Buried Plastic Sewer Pipes
It is often discussed which pipe ring stiffness should be used when designing the long-term deflection of buried plastic sewer pipes; the short-term value or the long-term value? As the...
Whatever Happened to Long-Term Bridge Design?
The Chairman of the Board of one of the leading engineering firms in the nation ponders the future of American bridges. In today's designing of bridges, Thomas R. Kuesel points...
Seam Examination
Charron discusses the importance of seam sampling in geomenbrane installation. In 1988, about 30 million mi of polyethylene geomembranes were used to line landfills, liquid impoundments,...
Design of Ductile Iron Pipe on Supports
Design procedures for ductile iron pipe in normal underground service have been well established. The standard design considers hoop stresses in the pipe wall due to internal hydrostatic...
Design of Drainage Pipes Below Landfills
Drainage pipes are an essential component of landfills. Even though their embedment conditions differ substantially from those of pipes for municipal utilities near the ground surface,...
Designing Vitrified Clay Pipe Systems with EASE
NCPI has developed a computerized trench load design program which provides a broad and complete spectrum of design options which will enable engineers and contractors to safely design...
Optimal Design of Water Transmission Mains
Capital cost for constructing a water transmission main includes cost of the pipeline and its associated installation costs. Also included in the capital cost is the cost of a pump station....
A Look Back in Time to Verify Life Cycle Cost Analyses
The proper engineering design of any hydraulic structure requires consideration of different but interrelated fields of: 1) Planning, 2) Hydrology, 3) Hydraulics, 4) Structural, 5) Installation,...
