Cyclic and Monotonic Undrained Response of Saturated Sands
A unified picture of the undrained monotonic and cyclic loading response of saturated sands is presented. A wide range of initial states of sand are covered in order to consider a full...
Shear Moduli Measurements under True Triaxial Stresses
The effect of state of stress on the shear wave velocity and shear modulus of a dry sand was examined. Testing was performed in a large-scale triaxial device in which cubic soil samples...
Centrifuge Model Testing with Dynamic and Cyclic Loads
This paper examines the use of small-scale tests on centrifuges to study a wide range of problems in soil dynamics - including machine foundations, structures and explosion effects. The...
The Uplift Capacity of Helix Anchors in Sand
Results of field and laboratory investigations of the uplift capacity of helix anchors in sand are presented. Equipment and instrumentation were used to measure uplift load, anchor deflection...
Uplift Capacity of Shallow Offshore Foundations
Soil failure under upward loading is investigated by experimental laboratory tests. The problem of uplift capacity is considered in terms of effective stresses in soil skeleton and pore...
Resistance of Shallow Inclined Anchors in Clay
Some recent laboratory model test results for the ultimate pullout resistance of a square anchor inclined at angles of 0, 20, 50, 75, and 90 degrees with respect to the horizontal have...
Forecasting the Demand for Electricity: An Examination of Alternative Approaches
This paper examines several approaches to forecasting national-level electricity demand. The various approaches are briefly examined, and the strengths and weaknesses of each are discussed....
The Role of Demand Forecasts in Pacific Northwest Power Planning
This paper has two primary objectives: to acquaint a general audience with the basic approaches used to forecast the demand for electricity, and to discuss the role of demand forecasts...
The Impact of Demand-Side Management on Load Growth: Some Tentative Results
Demand-Side Management (DSM) programs including load management, conservation and strategic load growth are being implemented by a very large number of utilities for the mutual benefit...
New Cables for Old
In an eingineering first, the main suspension cables will be replaced on New York City's Williamsburg Bridge without closing it to traffic at any time. According to the design...
Performance of Cogoti Dam Under Seismic Loading
At the time of its completion in 1938, the 280 ft (85 m) high Cogoti concrete face rockfill dam was exceeded in height by only one other dam of its type in the world, Salt Springs Dam....
Kotmale Dam and Observations on CFRD
A concrete faced rockfill dam was the type selected for the 300 ft (90 m) dam at Kotmale in Sri Lanka for reasons of economy and speed in construction. Standard design concepts were tailored...
Foundation Design Considerations for Detroit DPM
The design loadings for support of the elevated guideway of the Detroit Downtown People Mover (DPM) consist of high vertical as well as horizontal loads. In order to simplify foundation...
Structural Vibrations Associated with Large Incubation Tanks
It is the purpose of this paper to describe the format of an investigation wherein the train of evidence led from an assumption of a strictly mechanical cause to an actual cause that was...
Advances in High Strength Concrete,
The technology for producing field placeable concrete with a 28 day compressive strength of 10,000 psi has been available for many years. With the recent use of microsilica as an additive...
Aseismic Capability Prediction from Failure Data
Forensic engineering evaluations of failures have produced a wealth of technical data. In this paper, evaluation of representative failure data from one practitioner provided relevant...
Seismic Design-Qualification of Non-Safety Related Items in Safety Related Envelope
This presentation pertains to Seismic Design-Qualification for those portions of structures, systems, or components in a Nuclear Plant whose continued function is not required but whose...
Improved Management and Training in Public Transit
This paper presents a user-friendly, interactive method that can be used by transit managers to improve service efficiency and productivity. Using this method for evaluating operating...
Probabilistic Basis for Design Criteria in Reinforced Concrete
This collection of papers presents the results of research on the variability of reinforced concrete members carried out at the University of Alberta, Edmonton, Canada, during the period...
