Rockfill Compression Tests and Other Aspects of the Design of Miel I Dam
The Miel I Dam, a high concrete face rockfill dam, is one of the main structures designed for the Miel I Hydroelectric Project in Colombia. Selection of dam type was based on technical...
The Upstream Zone in Concrete-Face Rockfill Dams
The upstream zone of small rock, the supporting zone for the slab at many recent concrete-face rockfill dams has contained less than 20% of particles smaller than the No. 4 sieve. Such...
Need a Dependable Backfill?Try a Flowable Fly Ash
Flowable fly ash is a relatively new cementitious structural backfill material. It can be used in water or in the dry and will flow into place without the usual labor-intensive activities...
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...
A Summary of the Seismic Qualification Utilities Group (SQUG) Program
In December of 1980, the Nuclear Regulatory Commission (NRC) initiated Unresolved Safety Issue (USI) A-46 to address the question of the seismic adequacy of equipment in 49 operating nuclear...
Obtaining Reliable Data from Fragility Tests
The parameters discussed in this paper are the same as those present in normal seismic qualification testing. These parameters behave differently in high level acceleration tests and their...
Earthquake Experience Data on Power and Industrial Structures: Applications to Seismic Design and Evaluation
An extensive study was conducted to document the seismic performance of typical power plant and industrial structures in selected recent strong earthquakes and to correlate the performance...
Impact on Test by Various Multiaxis Excitation
The purpose of this paper is to provide input guidelines in evaluating various types of multiaxis excitation on fragility level testing of electronic devices. There are many variables...
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...
Physical Evaluation of a Buried Drainage System
The drainage problem in the 600,000 acre (1. 5 million ha) Westlands Water District (District), located in the Central San Joaquin Valley in California is that of a perched saline groundwater...
Time Rated Infiltrated Depth Families
A new set of infiltration families has been developed, for 'normal' soils to describe cumulative infiltrated depth versus time. This new family of curves is described...
Strength of Soils in Terms of Effective Stress
The factors that determine soil strength, such as amount of confinement, density, particle size distribution, mineral friction, aging, particle crushing, and others, produce their effects...
Recent Developments in Resonant Column Testing
The resonant column method of testing soils is reviewed. Recent developments in equipment, specimen configurations, and testing schemes are presented. Some equipment can perform both resonance...
Limits on Dynamic Measurements and Instrumentation
The implementation of the FFT (Fast Fourier Transform) into portable instrumentation has contributed to advances not only in signal analysis but also to new and improved transducers for...
Shallow Seismic Exploration in Soil Dynamics
Methods of shallow seismic exploration of soils are continually developing and evolving. Advances in techniques and equipment for performing crosshole and downhole tests, new data on interpretation...
