Seismic Decision Analysis for Jackson Lake Dam
This paper presents a framework for decision analysis that can be applied to seismic dam safety problems. The framework provides a means for displaying uncertainties in a manner that allows...
Maximum Response of Buildings to Multi-Seismic Input
The paper presents a technique of determining the maximum response of a torsionally-translationally coupling structure subjected to three ground translational components. It was found...
Comparisons of Full Scale and Wind Tunnel Model Response to Wind of Long Span Bridges
There are several vital reasons for measuring the response of full scale structures to wind and comparing the results to models - both experimental and analytical - employed in design....
Suspended Polycarbonate Shield to Defeat Terrorist Threats
The Navy Civil Engineering Laboratory is conducting research on a window concept that offers great potential for overcoming the disadvantages of blast resistant windows. The concept is...
Limiting Performance and Design by Reanalysis of Structures for Blast Resistance
Limiting performance is the absolute optimal response of a structure under a specified transient load. Reanalysis methods are computational techniques for analyzing locally modified large-scale...
Behavior and Design of Semi-Rigid Composite Frames
Recent advances and experimental research on the behavior of composite semi-rigid frames indicates that substantial savings can be achieved with this method of construction. The current...
Design of Steel Buildings for Second Order Effects
Several methods of calculating corrected effective length factors for unbraced frames are presented and discussed. In addition, an alternate format is suggested for the ASD beam-column...
New Directions in the Application of Probabilistic Concepts in the Seismic Analysis of Nuclear Power Plants
During the last 8 years, probabilistic concepts have been used in the seismic analysis of nuclear power plants. Probabilistic risk assessment (PRA) has been the primary vehicle for performing...
Detecting Underground Piping Leaks
Most leaks from underground liquid storage systems occur in the piping rather than the tank itself. The piping system is the most vulnerable component of the system, requiring great care...
Hydraulic Engineering
The papers in this book were presented at the ASCE National Conference on Hydraulic Engineering, August, 1987, Williamsburg, Va. The objective of this conference was to provide a forum...
Operational Experiences With a Wells Turbine on a Wave Powered Navigation Study
The objective of the research programme was to design a 100W Wells turbine generator unit which could be matched to standard tail tube buoys. Optimization of the power conversion chain...
On the Performance of a Wave Power Converter
This paper presents the KN-principle for wave - power conversion. The principle and components of the wave power converter are described and some practical relations are presented in order...
Shake-Proof Dams
Seismic trouble spots in California and along the Pacific Coast usually get the most publicity. But many people don't realize that Wyoming, Illinois, South Carolina, Utah...
Digestor Do-Over
Digesters at 6 Orange County (Calif.) wastewater treatment plants needed drastic odor control rehabilitation. Repairs included epoxy patching to cracked domes, installation of a geomembrane...
Capacity Increase of Multi-Jet Pelton Turbines
The recent connection to the grid of large capacity thermal stations, to meet the increasing demand, has entailed an evolution in the type of services required from storage plants with...
Planning and Designing the Powerplant at Stampede Dam
Power development at Stampede Dam was complicated due to the uncertainty about future reservoir operation and the need to design for seismic risk while attempting to minimize overall cost....
Valuation of System Hydro Additions
The purpose of this paper is to examine the major factors and steps which affect the valuation process of adding hydro power plants to an integrated hydro-thermal generation system. Results...
Hydraulic Machines Model Acceptance Tests
The article begins with a description of the modern test installations, giving the dimensions of the models most frequently used and the head heights. Attention is then given to the most...
Hoover Dam Earthquakes Reconsidered
In 1936 and 1937 as the water rose behind Hoover Dam, earthquakes were felt in the Boulder City area and as far away as Las Vegas. Interest in induced seismicity was renewed in 1967 with...
Thermal Monitoring of Leakage Through Dams
The technique involves very accurate temperature measurement at shallow depth below the reach of the surface diurnal cycle. Temperatures respond to subsurface water movement (with advective...
