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...
Curved Sewers: Yes or No?
A study of curved sewer use in Southern California examines sewer design and maintenance of curved versus straight sewers. A telephone survey of personnel in design and maintenance of...
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...
Repair�Don't Replace�Cracked Sewer Pipe
Approximately 0.5 mile (0.8 km) of 42 in. (1,07 m) diameter reinforced concrete was installed for a sanitary sewer project when the on site inspector discovered that numerous joints had...
The Sand Dam
Currently under construction is the 443 ft. high sand fill dam. Being erodible, pervious and liquefiable, sand would normally be considered as n unsuitable material to construct LaVueltosa...
Seismic Risk and Decision Analysis of Lifeline Systems
This paper provides general guidelines for performing lifeline seismic risk and decision analyses. Relevant input models are introduced as they support the performance of component and...
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...
Update on Impact Effects in Nuclear Plants Part I?Overview and Need for Integrated Approach
In this paper, an ASCE working group on impact effects in nuclear plants updates the review of this technology contained in a five-year-old ASCE report. In Part I, an overview is given...
Pipe Impact on Concrete Slabs
A series of pipe impact on concrete slab tests have been performed at the CEA's Cadarache Laboratory using the AQUITAINE II facility. The testing program was jointly sponsored...
Design for Whipping Pipe Impact on Reinforced Concrete Panels
This paper describes determination of local and overall effects on reinforced concrete panels due to whipping pipe impact in postulated pipe break events. Local damage includes the prediction...
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...
