Limiting Tip and Side Resistance: Fact or Fallacy?
The tip and side resistances of deep foundations do not reach a limit at a critical depth; instead, they increase with depth. For the tip, the rate of increase decreases with depth. For...
A Structural Engineering Perspective for Drilled Shafts
This commentary is an attempt to close the gap between the Building Code Requirements for Reinforced Concrete (ACE 318-83) and the design of drilled shafts. The context of design includes...
Abrasion Resistance of Polyethylene Dredge Pipe
In recent years there has been a slow but steady increase in the number of dredges using high density polyethylene (HDPE) pipe in discharge lines. HDPE's increased popularity...
Field Flow Measurement of Hydro-Turbine Efficiency
Performance tests were conducted at Great Northern Paper (GNP) Company's Weldon Hydroelectric Station. The purpose of the tests was to calibrate the Winter-Kennedy taps and...
Hydro-Thermal Power Plants with Pumped Storage
The concept of pumped storage can be justified through the development of hydro-thermal power plants. The hydraulic equipment for power plants of this kind is available in the market meeting...
Integrated Small Hydro Energy Development
Small hydro power development integrated with other renewable energy sources is economical. Civil engineering components if suitably selected and designed reduce power development costs...
Hydrogen Cycle Peak Power at Low-Head Sites
A major draw back to further development of low-head hydro power is that it usually uses run-of-the-river operations. The storage potential for peaking power production that large reservoirs...
Walden Hydroelectric Power Project
The Wallkill River at Walden, New York, produced hydroelectric power from 1909 to 1966. Using turbines dating back to the original hydroelectric development, the Walden hydroelectric station...
Modeling Pool and Riffle Sequences in Alluvial Channels
A one-dimensional mathematical model has been developed to predict the hydraulic characteristics of alluvial channels under low flow conditions. For a given steady discharge, channel geometry,...
Plastic and Other Limit State Methods for Design Evaluation
These proceedings consist of seven papers dealing with the topic of the design of complex structures using limit state methods. The emphasis is on the role of plastic or limit load techniques....
Structural Plastics Design Manual
The structural behavior of plastics reflects a number of characteristics different from those of the metal, lumber, and concrete materials familiar to most design engineers. This manual...
Guidelines for Transmission Line Structural Loading
Procedures are provided for the selection of design loads and load factors based on the latest research and state-of-the-art design techniques. This selection has an effort on the reliability...
Recent Developments in Pavement Skid Resistance
As pavements wear, they lose some of their skid resistance. This article discusses some of the leading options for restoring a pavement's skid resistance. The possibilities...
Seismic Design of Embankments and Caverns
The papers included in this publication were presented at three symposia on seismicity and seismic design for embankment dams and underground openings. Primary topics for discussion include:...
Restoration
After the San Fernando earthquake of 1971, California's State Capitol Building was declared an earthquake hazard and vacated. It took the most extensive structural and architectural...
Hydro Recovery
The largest water utility in southern California is discovering that it makes sense to generate electricity too. During the past four years, the Metropolitan Water District of Southern...
West Coast High-Rise Condo Opts for Ductile Concrete Frame
In the past, the vast majority of high-rise buildings constructed in earthquake prone areas of the West Coast have employed a steel frame. However, recent advances have made it feasible...
Design of Bridges for Ice Forces
Sources of knowledge on ice forces and ice effects on bridges are listed and discussed briefly. Comments are made on experience of damage by ice and on the influence on bridge costs of...
Journal of Energy Engineering
The Journal of Energy Engineering reports on the scientific and engineering knowledge in the planning, development, management, and finances of energy-related programs. The journal is dedicated to civil...
Building Failures�Preventing Them, Learning from Them
Ways to design and construct a structure so as to minimize chances of errors leading to failure are described. Held up as models of systematically investigating failures are the incident-study...
