Structural Design, Cementitious Products, and Case Histories
The papers in this book represent deverse topics in structural engineering. In design of beam-columns by the AISC interaction equations, it is demonstrated that an inadequacy exists when...
Tunneling a Bridge
Linking an addition to the Georgia World Congress Center in Atlanta required a pedestrian tunnel through a railroad embankment 100 ft wide and 40 ft high, with no disruption of train service...
Advances in Short Span Steel Bridges
Applying recent research to the design of short span steel bridges can lower their cost and maintenance. Such research involves improved limit state criteria, more uniform lateral load...
Jointless Bridge Decks
Deck joints in a bridge are the source of many problems over its lifetime. In time, chances are good the joint will leak, permitting water and salt to leak through. Often this leads to...
Slurry Walls Protect Harvard Square
Harvard Square Station, Cambridge, Mass., had to be rebuilt when Boston's Red Line Subway was extended further out to the suburbs. For the first time, tied back slurry walls...
Current Corps of Engineers Concepts for Roller Compacted Concrete in Dams
Since construction of Willow Creek Dam in 1982, Elk Creek Dam in southwest Oregon is the only Corps of Engineers dam to be constructed using RCC that has passed beyond the planning stage...
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 Two Spillways Using Roller Compacted Concrete
Roller Compacted Concrete (or RCC) is a relatively new method of construction and in many projects can be a low cost alternate to or foundation for conventional reinforced concrete. The...
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...
Construction of Recent RCD-Concrete Dam Projects in Japan
The Japanese Ministry of Construction has organized a committee which has been promoting research concerning rationalized concrete dam construction. A part of this research is the work...
Upper Stillwater Dam Construction Program
Utilizing both proven and innovative construction techniques, equipment, and design concepts, Tyger Construction Company Inc. , located in Spartanburg, South Carolina, has undertaken the...
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...
Underground Building Reclaims a Landfill
Oregon's Multnomah County built a road and maintenance facility underground to begin reclaiming an old landfill site. More than 600 precast concrete components make up the...
Redecking with Precast Keeps Traffic Moving
The Woodrow Wilson Memorial Bridge in Washington, D.C. could not be closed to traffic while a new deck was constructed. The engineers designed a precast prestressed and post-tensioned...
Rail and Road Traffic Continue During Bridge Modification
The crossing of Route 15 under the Bangor and Aroostook Railroad Bridge, Bangor, Maine had limited sight distance and marginal clearances. Maine Department of Transportation, therefore,...
Steel Girder Bridge Sets Record Length
The Veterans Memorial Bridge at Ottawa, Ill., is the longest plate girder, stringer type bridge in the country with spans of 385, 510 and 305 ft. Value engineering played an important...
River Lock Rehab: A Winter's Tale
