Design of Tunnel Lining from Shotcrete in Combination with Anchors
The method of designing tunnel linings from shotcrete in combination with anchors is given in the paper. The method is based upon the solution of the plane contact problem for a double-layer...
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...
Two Shotcrete Lined Tunnels in the United Kingdom
The paper describes two large diameter tunnels recently built in southern England where shotcrete has been used as the primary support. The design methodology is described together with...
Adapted Actions Taken at Too Low Shotcrete Quality
A tunnel contract specified quality parameters such as: thickness, compressive strength, adhesive strength, bending tensile strength and residual bending tensile strength for fibre reinforced...
Guidelines and Recommendations on Shotcrete?An International Compilation
Part of the work within the International Tunnelling Association's (ITA) working group Shotcrete Use has been to compile existing guidelines and recommendations concerning shotcrete, particularly...
Recycled Roads
The movement to recycle wastes in highways appears to be gathering momentum nationwide. Rubber from old tires, wood chips, reclaimed asphalt pavement, fly ash, scrap plastic, mining wastes...
Driving Under a Construction Site
Throughout the summer of 1992, vehicles passed unimpeded through one of the most heavily traveled intersections in Los Angeles County as construction proceeded on a concrete light-rail...
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...
Interim Dry Storage of CANDU Fuel
The Canadian approach to permanent disposal of used CANDU fuel is directed toward its storage in suitable containers emplaced into an underground, stable, plutonic rock formation. Reprocessing...
Cask Storage Verification Test?Full Scale Test
In Japan, the cask-storage method of spent fuel will be licensed in the near future and the related R&D works (partly of the Japanese Government have been carried out mainly by...
Code Requirement for Concrete Repository and Processing Facilities
Because of varied uses and performance/safety requirements of concrete for high, medium and low level radioactive wastes, a review of the current ACI 349 Code document was carried out...
Wynoochee Lake and Dam?Flood Storage Reevaluation Study
With the desire to increase the revenue generating potential of the Wynoochee Lake and Dam Project the cities of Tacoma and Aberdeen, Washington, have pursued the potential for retro-fitting...
Analysis of Operating Criteria: Multiple Lakes at Voyageurs National Park
An overview of lake and river regulation at Voyageurs National Park, which resides on the Minnesota-Ontario border, is given to demonstrate how water policy agreements can work. In 1905...
Hydrologic and Structural Considerations for the Initial Filling of Jiguey Dam, Dominican Republic
This paper describes the hydrologic and structural considerations of the initial filling of Jiguey Dam which is locate on the Rio Nizao about 100 kilometers west-northwest of Santo Domingo...
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...
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...
Time-Dependent Nonlinear Analysis of Cable-Supported Prestressed Concrete Bridges
A method of analysis and a computer program CFRAME for the material and geometric nonlinear analysis of cable-supported planar prestressed concrete bridges including the time-dependent...
Object-Oriented Modelling for Concrete Structures
The use of computers for the design process has reached wide acceptance. The use is developed in several fields such as CAD, CAM or programs for design of structural elements. Recent work...
Grillage Analogy for Multigirder Bridges
Grillage analogy is a method frequently used to simulate the structural response of highway bridges with reinforced concrete deck and steel girders. This approach saves substantial efforts...
