Simplified Seismic Analysis of Pile Foundations
The determination of displacement of the pile cap and displacements and forces of individual piles is essential to the design of pile foundation subject to both static and/or dynamic loading....
Seismic Response Considerations in Foundation Design
There are no generally accepted procedures to determine the potential magnitude of reduction of footing bearing capacity that may result from soil strains or pore pressure changes during...
Some Observations on Undrained Side Resistance of Drilled Shafts
A data base of 106 field load tests (65 in uplift and 41 in compression) is used to evaluate the undrained side resistance of drilled shaft foundations. The total stress or alpha (?) method...
Nondestructive Testing of Deep Foundations with Sonic Methods
Nondestructive testing and evaluation (NDT&E) of deep foundations with three sonic methods is discussed. Case history investigations described include test records from drilled...
Geophysical and Nuclear Methods for Non-Destructive Evaluation of Caissons
Non-destructive testing techniques were used to confirm the concrete integrity on the caisson foundations for the 45-story Ohio Corporate Headquarters building in Cleveland, Ohio. The...
Computer Utilization in Structural Engineering
This volume contains the papers presented at the 1989 Structures Congress sponsored by the Structural Division of the American Society of Civil Engineers that deal directly with the application...
Seismic Engineering
Research and Practice
This volume of Seismic Engineering: Research and Practice contains papers from twenty-two sessions of the 1989 ASCE Structures Congress. These papers represent a wide-ranging interest...
Steel Structures
The seventy-eight papers included in this volume cover the fifteen sessions generally associated with steel structures presented at the Seventh Annual Structures Congress held on May 1-5,...
Drought Investigations by the Use of Maximum Daily Temperatures
By the use of maximum daily temperature data, drought events can be defined by taking a certain truncation level to form the partial drought duration series. A drought series representing...
Earthquake Effect on Sediment in Rivers and Deltas
Many authors have studied the age and distribution of the Holocene deltaic deposits of the Mississippi River. Several others have written about the magnitude and the recurrence interval...
Routing a Cold Water Release Through TVA Reservoirs to Control Intake Temperatures at a Power Plant
A volume of cold water was routed some 160 miles through the TVA reservoir system to keep a nuclear plant intake temperature within safety limits. Mathematical modeling of the operation...
Greenhouse Effect on Estuarine Saltwater Intrusion
A report by the British Department of the Environment calls for research into the effect of a rise in world temperatures on sea levels. Model studies should investigate changes in the...
Experience with Cavitation in High Pressure Slide Gates
The Bureau of Reclamation has many years of experience in the design and operation of high pressure slide gates. This paper discusses the historical use of high pressure slide gates by...
Effects of Climate Change on Watershed Runoff
This paper examines forecasts of changes in watershed runoff in the Delaware River basin that result from a range of predicted effects of increased atmospheric carbon dioxide (CO2)...
Seven Oaks Dam Outlet Works Design
The U.S. Army Corps of Engineers has completed the preliminary design of the outlet works for the proposed Seven Oaks Dam. The dam is the upstream-most feature of the Corps'...
Scale Effects at Intakes Due to Boundary Layer Growth
Boundary layer development in hydraulic models of intakes based on Froude criteria can be poorly scaled because it is viscosity dependent. The potential for scale effects can be estimated...
Design of Isolated Small Hydro Stations
This paper presents some ideas concerning the criteria for the design of small hydro power stations operating isolated, and specially those to be installed in remote areas. Subjects covered...
Newfoundland's First Arch Dam Construction Versus Climate
Paradise River arch dam is located in a narrow box canyon about 50 m deep and less than 10 m wide at streambed. It is a thin arch dam, especially sensitive to temperature loads, thus contraction...
Problems Associated with Large Hydro Generators
Since the early 1950s, hydro generators have increased in size from the 50 MVA range to much larger units employed today, many of which are in excess of 500 MVA. Such a tenfold increase...
Critical Features of Custom Design Hydro Gates
Large hydro gates are custom designed to suit each particular installation. To prevent overlooking a feature that could lead to future problems, a check list of the numerous features should...
