Steel Fiber Reinforced Shotcrete?An End-User Prospective
Nearly 15 years of experience demonstrates that steel reinforcing fibers in shotcrete offer considerable advantages to all end-users: designers, contractors and owners. These include demonstrable...
Large Scale Testing of Shotcrete
A large scale test program was carried out to evaluate the relative roles of steel fiber and mesh reinforced shotcrete for hard rock stabilization. The most realistic conditions in a tunnel...
What Does Bring Ductility to Steel Fibre Reinforced Shotcrete?
It is generally accepted that ductility is the main characteristic of SFRS. Tests on scale 1/1 have been conducted to determine the influence of ductility on the bearing capacity and crack...
A Comparative Study of Different Steel Fibers in Shotcrete
Two steel fiber reinforced shotcrete (sfrs) test programs have been carried out in eastern Canada using steel fibers which are available in the north American marketplace. The first program...
The Use of Yield-Line Theory in the Design of Steel-Fibre Reinforced Concrete Slabs
Using yield line calculations for steel fibre reinforced slabs a formula for the design strength of shotcrete linings is developed. The formula establishes a connection between the toughness...
Steel Fibre Reinforced Shotcrete Design
There is a need for introducing toughness and ductility in SFRS design. The Japanese Standard introduces the equivalent flexural strength, which characterizes SFRS toughness and allows...
Application of Shotcrete for Ground Support at Inco Mines
In 1989, shotcrete was first successfully introduced for ground support in production areas at Frood Mine. Until then the only successful application of shotcrete had been in major permanent...
MASSPORT Modernization
Construction began last fall on the Massachusetts Port Authority (MASSPORT) upgrade of the 50-year-old Paul W. Conley Terminal in Boston. When completed in 1994, this timber-pile-supported...
Supply-Side Solutions
Although the crumbling bridge infrastructure has received much attention in the press and the engineering community over the past few years, the number of structurally deficient bridges...
Plastic Piling
Composite plastic and steel piles are gaining acceptance throughout the United States. The evolving technology has produced a unique product which solves several problems related to use...
TVO-92 Safety Analysis of Spent Fuel Disposal
Spent fuel from the TVO I and TVO II reactors is planned to be disposed of in a repository to be constructed at a depth of about 500 meters in crystalline bedrock. The fuel will be encapsulated...
Marginal Overweight Operating Scenario for DOE's Initiative I Highway Casks
This paper assesses the potential transport of high-capacity Initiative I highway casks under development by the Office of Civilian Radioactive Waste Management (OCRWM) as permitted marginal...
Post-Test Evaluations of Waste Isolation Pilot Plant?Savannah River Simulated Defense HLW Canisters and Waste Form
Eighteen nonradioactive defense high-level waste (DHLW) canisters were emplaced in and subjected to accelerated overtest thermal conditions for about three years at the bedded salt Waste...
Corrosion Life-Time Assessment of Carbon Steel and Stainless Alloys for Geological Disposal Facility
The disposal facility for radioactive wastes, requires long-term integrity. Metal is considering to use as the engineered barrier which constructs the outer walls in such a facility, in...
Localized Corrosion Prediction for Nuclear Waste Disposal Container Materials
When the bentonite is used in the geological disposal of high-level wastes as a buffer material to stand between containers and host rocks, thereby turning the pH of the groundwater slightly...
Columbia River Basin Fish and Wildlife Program Strategy for Salmon
Three species of Snake River salmon have been listed as threatened or endangered under the federal Endangered Species Act. In response, the Northwest Power Planning Council worked with...
Alternatives Analysis Using Two-Dimensional Modeling for the Owensboro Bridge and Approaches
The Federal Highway Administration plans to design and construct a new bridge over the Ohio River near Owensboro Kentucky. A hydraulic model with two-dimensional capabilities was utilized....
A Structural Analysis System
In this paper, the importance of the structural analysis in accordance with the construction progress was emphasized to accurately predict the structural behavior of prestressed concrete...
Computer Analysis of Cable-Stayed & Suspension Bridges
The finite element structural analysis of long span bridges is an area of research that has been studied within the past thirty years since the development and emergence of the digital...
Modeling Beam Torsion in Prestressed Concrete Box Beam Bridges
This paper briefly summarizes the development of a specialized finite element model capable of predicting the elastic and inelastic behavior of beam-slab type prestressed concrete spread...
