Modeling of a Multifunctional Hydraulic Structure
A 1:12 scale Froude model of a hydraulic control structure in the Rochester Combined Sewer Overflow Abatement Program (RCSOAP) was constructed and tested to optimize the design requirements...
Controlling River Ice to Alleviate Ice Jam Flooding
Many communities affected by ice jam flooding have accepted the event as unpreventable. Others have approached their problem as one of open channel flow and implemented standard projects...
Modeling Intake Performance Under Frazil Ice Conditions
A water intake was modeled in a refrigerated flume in an active frazil icing environment in order to evaluate alternative modifications to the prototype structure. Tests were run until...
Fisheries Engineering Program at Washington State University
Problems associated with the interrelationships of instream hydraulic structures, and migratory and resident fish, are in need of better analysis and design. This improvement can be realized...
Modifications of Dams for Recreational Boating
Many existing dams and river structures require modification, and new structures may need to include designs to allow safe white water activities. The basic problem is safety, with a long...
Current Hydraulics Research at the Iowa Institute of Hydraulic Research
The Iowa Institute of Hydraulic Research is engaged in fundamental and applied research on a broad range of fluid mechanics and hydraulics problems. The history and organization of the...
Bureau of Reclamation Hydraulic Laboratory
The Bureau of Reclamation used hydraulic models for the first time in 1930 in the laboratory of the Colorado Agriculture Experimental Station in Fort Collins, Colorado. In 1946 the Reclamation...
Pipeline Materials and Design
The proper use of pipeline materials and design is obviously paramount in the private and public works sectors. The introduction and proper use of new piping materials and design procedures...
Structural Engineering in Nuclear Facilities
The papers in this publication cover the general theme of civil and structural engineering as they are applied to nuclear facilities. Traditional topics include seismic analysis, impactive...
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...
High Tech Is More Than a Look
Hollow steel section, also known as tubular steel, is being used for its clean dramatic look, its structural efficiency in compression, the economic efficiency of combining structure and...
Retaining Walls: Competition or Anarchy?
Until the last 10 years, when a retaining wall was needed a cast-in-place concrete gravity or cantilever wall was used. Then along came Reinforced Earth, and this proprietary system began...
Inspecting Buildings During Construction: Are We Doing a Good Enough Job?
Everyone agrees that inspecting buildings during their construction is important�and that it could be done a lot better than in the past. Suggestions for improving inspection practice...
Electronic Computation
Dramatic changes have occurred in computer-aided structural engineering during the past 25 years. Computers have evolved from large, slow processors with little available storage to fast...
Pre-Engineered Metal Buildings: The Story Behind Their Rapid Growth
In 1964, pre-engineered metal buildings accounted for 24% of new non-residential, low-rise construction. By 1981, that figure had jumped to 56%. Behind that rapid growth are some very...
Coastal Structures '83
The objective of the conference Coastal Structures '83 was to develop in-depth discussion of the state-of-the-art and future needs concerning coastal structures. Design, construction,...
A Rapid Method of Computing Geometric Relations in Structural Analysis
A rapid method of computing geometric relations in structural analysis is presented. The method is shorter than usual methods, in many cases, and can often produce a result in one step....
The Quiet Revolution in Skyscraper Design
Since the 1960's, there has been a major change in the philosophy for designing high-rise buildings. Up to that time, most buildings were designed to resist wind forces by...
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:...
Design for Ice Forces
Part one of this publication on design for ice forces emphasizes offshore and coastal structures. In this section , seasonal ice conditions typical of offshore and coastal zones are reviewed....
