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
Engineering for Steel Construction, just published by the American Institute of Steel Construction, limns the latest advances in detailing...

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...

Strength and Stiffness Characteristics of Steel Ladder-Type Cable Trays
Ladder-type cable trays identical with the as-built are generally tested to establish their strength and stiffness characteristics. Test data for systems in operating plants, however,...

Composite-System Approach for Seismic Analysis of Secondary Systems
An accurate and efficient method for seismic analysis of multiply supported, multi-degree-of-freedom secondary subsystems is developed. The method accurately accounts for the effects of...

Development of Concrete Nuclear Containment (ACI 359) Code Requirements as they Relate to Probability Based Load
The historical development of the load combinations used in concrete containment is presented in the paper. These load combinations are examined and identified in the light of the reasonable,...

Containment Capability
Section 2. 0 of this report contains a description of analysis methods for the containment structure. Testing on containment models and sections of containments is described. Section 3....

Sodium Concrete Reaction ? Structural Considerations
An overview of the sodium concrete reaction phenomenon, with emphasis on structural considerations, is presented. Available test results for limestone, basalt, and magnetite concrete with...
