Stochastic Propagation of Semi-Elliptical Surface Cracks
Random propagation of a semi-elliptical surface crack is investigated as a bivariate stochastic process. Under a few assumptions, a probability distribution of the surface crack propagation...
Secure Landfills: Reliability-Based Analysis and Design
A framework is outlined for reliability-based analysis and design of secure landfills. Reliability, R, is the estimated probability landfill leakage, Ql, is below an allowable limit, Qf;...
Approximate Reliability Analysis of Highway Bridges Under the Action of Random Vehicles?In Relation to an Interchange Bridge of China
In relation to an interchange curved bridge of China, a simple method by FSE for analysis of stochastic vibration has been proposed. The random vibration characteristics of bridge structures...
Reliability of a Suspension Bridge Under Traffic Flow
The problem of reliability of a single-span spatial suspension bridge under random highway traffic is considered. The displacements of the bridge are described by coupled, non-linear,...
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...
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...
Earth Pressure Acting on Buried Flexible Pipes in Centrifuged Models
Distributions of both normal and tangential earth pressures acting on three flexible model pipes having different wall thicknesses were successfully measured in centrifuge model tests....
Recent Advances in Structural Rehabilitation Techniques for Underground Sewer Pipelines
A great challenge for the coming years, if not decades, will be the repair, renovation and renewal of the existing sewerage systems in the Federal Republic of Germany in the interest of...
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...
