Concrete Face Rockfill Dams?Design, Construction, and Performance
Concrete face rockfill dams are being used with greater frequency and to greater heights in the last decade. The developments leading to this progress are many and are addressed in the...
Predicting Sinkhole Collapse
Sinkholes erupt when a cavern or opening in the limestone rock below opens up to the surface. Florida's sinkholes have received most U.S. attention recently, but sinkhole geology is found...
Tunnel Shotcreting�Strength in Fibers
Steel fiber reinforced shotcrete (SFRS) costs less, has a lower rate of rebound and allows modern excavating equipment to advance with fewer interruptions than conventional shotcrete....
Watertightness and Seepage Control in Roller Compacted Concrete Dams
An unjointed mass of roller compacted concrete (RCC) can easily be proportioned and compacted so that it is essentially impermeable and 'watertight. ' Permeability tests of various field-placed...
Roller Compacted Concrete Pavements in British Columbia, Canada
Roller Compacted Concrete (RCC) pavement is an outgrowth of the traditional cement-treated aggregate base (soil-cement) method of street and highway construction. The major use in British...
Simplified Design and Construction Control for Roller Compacted Concrete
This paper presents a simplified approach to the design and construction quality control of roller compacted concrete (RCC) based on research of previous projects, discussions with experienced...
Construction of Middle Fork Dam
Recently there has been increased interest in roller compacted concrete (RCC) for use in dams. However, to date there has been very little practical experience in construction. Middle...
Economic Considerations in Selection of a Roller Compacted Concrete Dam
Roller compacted concrete (RCC) has recently emerged as an economically attractive material for gravity dam construction, replacing the use of conventional concrete and even challenging...
USBR Design Considerations for Roller Compacted Concrete Dams
Current Bureau design criteria for concrete dams are based on analytical methods developed and improved over the years, evaluation of construction methods and post construction materials...
Engineering for Steel Construction
Establishing Patterns of Building Failures
Establishing statistical patterns of building failures can help engineers and architects prevent similar failures in the future and also reduce litigation. The Architecture and Engineering...
Innovative Engineering Completes Dredge Spoil Disposal Facility
A large dredge spoil facility was completed for the Fort McHenry Tunnel that received 3.5 million cu yds of dredged material, and was constructed so that it could be converted into a port...
Flowable Fly Ash: A New Cement Stabilized Backfill
Cement stabilized fly ash placed at a plastic fluid consistency is a new structural backfill material that flows into place, either above or below water, without using sophisticated construction...
High Rise Design: Accounting for Column Length Changes
In the late 1950's and early 1960's, the height of concrete buildings jumped from 20 to 60 stories. During the same period, architects introduced the use of exposed...
Probabilistic Nature of Soil Properties
The integrity of a soil material is defined not only by its compositional components but also by the constituent natural bonds and the resultant interactions between the various constituents...
Fire Combustion Toxicity Tests�Good Idea or Not?
The smoke from burning synthetic materials in buildings is highly toxic and is a key cause of deaths in building fires. If fire codes regulate on the basis of the toxicity of smoke of...
Performance of Water and Sewer Lifelines in the May 2, 1983 Coalinga, California Earthquake
Water supply and filtration systems for the City of Coalinga suffered little damage. The water transmission system suffered five breaks. The urban distribution system was disrupted, but...
Ocean Energy
The Ocean Thermal Energy Conversion (OTEC) component nominated this year as an ASCE Outstanding Civil Engineering Achievement involves the most critical design problem; the cold water...
Low Velocity Impact Tests on Reinforced Concrete Panels
The results of low velocity impact tests on reinforced concrete panels are presented. These tests were conducted to investigate the behavior of reinforced concrete flexural elements subjected...
Major Considerations in Scale Modeling of Reinforced Concrete Containment Structures
Reinforced concrete containment structures pose unique modeling problems, especially when leakage integrity is of interest. This paper presents a general discussion of modeling considerations...
