Thaw Settlement as a Result of Permafrost Deterioration
An overview is given of floor and footing failure as a result of deterioration of permafrost. Consideration of causes for the deterioration and methods of repair are addressed in general...
Creep Rate Analysis of Pile Load Test Data
The uniform creep behavior of five driven piles and one slurried pile based on pile load test data are presented and analyzed. The incremental static load tests carried out by ARCO, Alaska...
A Beaufort Sea Deepwater Production Structure
There will be a need for large crude oil production platforms in Beaufort Sea water depths between 20 and 50 m and at locations with soft seabed soils and far from readily exploitable...
A Hybrid Structural Ice Defense Mechanism
A hybrid plate composed of steel outer surfaces and a concrete core has characteristics that make it desirable for use on offshore structures in ice prone environments. The service and...
Ice Forces on Port Structures Resulting from Moving Ships
Results are described of experiments carried out in Thunder Bay Harbour in March, 1984, to measure ice forces on a port structure. Ice forces were measured by installing five pressure...
Earth Pressure on Underground Concrete Pipe in a Field Test
The cause of cracking at the sheetpile extraction in concrete pipes buried by the open excavation method was investigated by loading tests on the pipe and a field test carried out by Osaka...
Maintaining a Natural Gas Pipeline in Active Landslides
This paper deals with a pipeline section on both sides of Douglas Pass in west Colorado. Landslide activity in the area has been causing considerable problems and disruptions of the pipe...
Quality Control Management of Real-Time Data
Recent improvements in the real-time acquisition of hydro-meteorological data have raised concerns regarding the quality of the data received. This paper presents several data verification...
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...
Initial Operation Model for the Central Arizona Project
A microcomputer program for operating uncompleted portions of the Central Arizona Project has been developed. Engineers may use this program daily to assist in scheduling pumping plant...
Local Pressure in Ice-Structure Interactions
Two models for the determination of local pressures during marine ice or iceberg collisions with bottom-founded structures are presented. The first model is a two-dimensional analytical...
Classification of Human Errors
Error control should be a primary part of any risk control strategy. Classification of errors may serve as a basis for the systematic analysis to eliminate the causes and to reduce the...
Random Vibration Techniques
The paper presents a review of random vibration techniques for analyzing dynamic systems from the perspective of applicability to structural engineering. Problems involving linear or nonlinear,...
A Damage Function Using Structural Response Measurements
A new damage function is proposed that expresses seismic damage in terms of the range and number of cycles of plastic deflection experienced by a structure. This and other damage functions...
Finite Element Methods in Structural Safety Studies
The use of finite element methods in structural safety studies is discussed and recent work in the area is briefly reviewed. Formulation for a first-order stochastic finite element method...
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....
Damage Model for Buildings Subjected to Earthquakes
A model based on random vibration method is developed for assessing building damage to earthquakes. The damage of reinforced concrete structures is expressed as a linear combination of...
Stochastic Beams on Elastic Foundation
The finite difference method is applied to the second-moment analysis of beams on elastic foundation with random characteristics. The method is simpler than the stochastic finite element...
Design Considerations for Wind Loadings
The application of reliability concepts to the treatment of wind loadings on structures has increased in the past several years. Advances have been made in assessing the various uncertainties...
Seismic Probabilistic Risk Assessment for Critical Facilities
