Utilizing Design Events Within Risk-Based Design
Design load selection based on the return period of an environmental event is not possible when the event is described by more than one parameter. Risk analysis can be used to associate...
Selection of Environmental Design Criteria for Arctic Structures
Where data are insufficient for calculation of extremes using probability theory, design criteria may be reasonable defined by combining available data, knowledge of physical processes...
Probabilistic Design of Gravity Foundations for Arctic Offshore Structures
The use of the probabilistic simulation technique to estimate the variability of the resistance and the ice load on arctic gravity structures is illustrated in order to assess the safety...
Creep Properties of Ice: Theory and Experiment
In recent years, intensive developments in Northern regions have increased the demand for solutions to a large number of engineering problems involving ice mechanics. In particular, these...
The Sand Mattress Method of Slope Protection
The sand mattress concept offers promise as an economical alternative to sand bag armor for two distinct applications: (1) slope protection for exploratory islands and/or causeway facilities,...
Pipeline Hardware: Special Designs for Arctic Projects
The hardware used to support and protect arctic pipelines has evolved through several years of innovative design work by various engineering firms. The hardware used on the Kuparuk River...
Ice Load Prediction with the Use of a Rate-Dependent Anisotropic Constitutive Law
Man-made structures built in arctic offshore areas are subject to ice loads. Traditional methods for estimating ice loads rely on an indentation factor from rigid-plasticity, an empirical...
Stochastic Finite Element Analysis of Gravity Platform Foundation
Gravity foundation design requires determination of total and differential settlement, vertical stress distribution beneath the raft and maximum shear stresses in the sand layers in the...
Dam Pioneers Concrete Variant
The Willow Creek Dam in Oregon is the nation's first dam made entirely of roller compacted concrete. The design and construction of this dam are described and special problems...
Biggest Highway Rebuild
The reconstruction of the Wisconsin Interstate 90 and 94 involved 32 miles of 6-lane pavement. Most of the concrete aggregate for the job was recycled concrete pavement and all pavement...
Methods for Reliability Analysis of Water Distribution Networks
A detailed review of the literature reveals that there is currently no universally accepted definition or measure of reliability for water distribution networks. The purpose of this paper...
Structural Considerations for a Radwaste Facility
The structural engineer needs to consider several criteria when designing a radioactive-waste processing facility in order to properly balance the requirements of safety and economy. This...
Seismic Pope Support Construction Practices
During the mid 1970's the regulatory agencies controlling the design and construction of nuclear power plants began to demand stricter adherence to already existing codes...
Modifications At Operating Nuclear Power Plants
In these days of continuing regulatory requirement changes and high interest rates, the engineering of structural modifications for operating nuclear power plants has taken on greater...
Civil Engineering Challenge with Nuclear Waste
The planning, design and construction of the ground surface facilities for a nuclear waste repository involves civil engineering in many ways. The transportation of heavy, metal shielded...
The 1984 novel
Making Treatment Plants Work
For the most part, past design criteria that have been used were based primarily on historical information from plants that worked or general rule of thumb criteria. With the increasing...
Concepts and Methods in Reliability-Based Structural Optimization
This paper presents an overview of the major concepts and methods used in reliability-based structural optimization. New formulations related to multicriteria optimization are developed....
Evaluation of Structures by Dynamic Load Testing
The Frequency Sweep Method for the evaluation of structures by dynamic load testing was developed by the senior author. It is a non-destructive testing (NDT) method that was originally...
Probability-Based Load Criteria for Structural Design
Load criteria for use in limit states design of structures are developed using probabilistic methods. Statistical data on load and strengths are integrated by the reliability analysis...
