Toward a Unified Approach to Anchorage in Reinforced Concrete Design
The introduction of rationalized design procedures for cast-in and post-installed anchors inEurope and the U.S. was intended to provide a uniform factor of safety for anchorages inconcrete,...
Cold Climate Solution
To reduce turbidity in sedimentation-basin discharge, Anchorage, Alaska, is experimenting with constructed wetlands to augment storm-water discharge treatment from several storm-drain...
Suspension Bridges Unplugged
The `coupling effect' between the flexible, suspended superstructure and the very stiff cable anchorage in suspension bridges can produce large motions during strong earthquakes....
Design
This chapter discusses guyed structure design. Topics include loadings and design restrictions; guy clearances; guy design; guy anchorage; connections; structural design of poles and H-frames;...
Creeping Suspicion
High-capacity, epoxy-coated anchors were installed at Upper Occoquan Dam to increase the stability of the 70-foot-high concrete gravity dam and powerhouse under revised Probable Maximum...
The Stabilization of Concrete Dams by Post-Tensioned Rock Anchorages: The State of American Practice
Permanent post-tensioned rock anchorages have been used for over twenty years in America to stabilize existing concrete dams and their appurtenant structures. This paper provides a state...
The Use of Post-Tensioned Anchorages on the Arch Portion of Stewart Mountain Dam, Arizona
Post-tensioned rock anchorages were selected by the Bureau of Reclamation (Reclamation) to stabilize Stewart Mountain Dam against potential seismic loadings. The use of such anchorages...
Advancing Anchorage Technology
An overview of earth anchorage technology, with emphasis on current U.S. corrosion protection practice as compared to that used in Europe. Comments from U.S. practitioners involved in...
Winter Sewer Construction in Campbell Lake
This paper discusses the winter construction for replacement of the Campbell Lake portion of the Campbell Creek C-5 Trunk (C-5 Trunk) located in Anchorage, Alaska (see Figure 1). A previous...
Anchoring?A New Generation
During the time period of NRC Bulletin 79-02, and certainly afterwards, the use and application of wedge type anchors in Nuclear Power Plants took on a new perspective. The data gathered...
Anchorage Sewer Rehabilitation in Campbell Lake

Development of the South Anchorage Transit Center: Public/Private Partnership in the Small Urban Area
Public/private partnerships are as useful a tool in smaller urban areas as they are in the larger cities. The arrangements are likely to be simpler and the number of actors fewer, but...
Influence of Epoxy Coating on Stress Transfer from Steel to Concrete
To assess the influence of epoxy coating on the bond characteristics of reinforcing bars, a series of tests was conducted to determine differences in stress transfer between coated and...
Stress Analysis of the Liner and Liner Anchorage System Near Penetrations in a Reinforced Concrete Reactor Containment
An overpressurization experiment was conducted on a scale-model of a reinforced concrete containment building. The test was terminated when tears formed in the steel liner. Virtually all...
Unbonded Performance
Unbonded single strand tendons have been used in the U.S. for about 30 years. In a small number of buildings, strand corrosion failures have occurred. Although it is clear that post-tensioning...
New Parallel Wire Bundle for Cable-Stayed Bridges
A parallel wire bundle is described which is twisted with a long lay length. It is corrosion protected by an inner fill and outer coating of polyurethane. It presents a specially shaped,...
Anchorage Forces for Z-Purlin Supported Standing Seam Roof Systems
This paper presents the results of a limited study to determine if the provisions of Section D. 3. 2. 1 'Anchorage Bracing for Roof Systems Under Load with Top Flange Connected...
Water Treatment Facility Design for a Glacial Lake
The Municipality of Anchorage, Alaska has undertaken a major water supply project, the Eklutna Water Project, to satisfy the growing water demands of Anchorage. The source of raw water,...
Transit Scheduling With Spreadsheets
