Fatigue Damage for Reinforced Concrete Offshore Structures
When concrete structures are subjected to fatigue loading - resulting from ice or wave loads - progressive damage occurs with increasing number of cycles. Nonlinear damage evolution equation...
Microsilica Concrete: Properties and Applications
With the advent of microsilica concrete, a new generation of high to ultra high strength and high durability concretes have become commercially feasible and are now being specified and...
North Sea Technology Transfer to the Bering Sea
Concrete platforms in the North Sea are reviewed, including technological considerations and economic factors involved in their selection and application. The applicability of this technology...
Developing a Drilling Structure for Arctic Waters
Fluor-Doris of Houston has developed a mobile, composite concrete and steel drilling structure called the Arctic Composite Platform (ARCOP). This platform is capable of operations in water...
Arctic Drilling and Production Platform Concept
An 80-well Arctic drilling and production platform for water depths to 100 feet in the Beaufort Sea transition ice zone is presented. It includes a novel inner caisson to help resist large...
Concrete Space Frame Applied to an Arctic M.O.D.U.
The BOUYGUES experience in the use of concrete space frame technology for civil works and the application of this technique, combined with high strength concrete and prefabrication, to...
Cost-Effective Arctic Concrete Structures
The economic development of offshore Arctic petroleum fields dictates that Arctic structures be both cost-effective and deliverable with minimum lead time. Concrete structures are typically...
Earth Pressure on Underground Concrete Pipe in a Field Test
The cause of cracking at the sheetpile extraction in concrete pipes buried by the open excavation method was investigated by loading tests on the pipe and a field test carried out by Osaka...
Dam Pioneers Concrete Variant
The Willow Creek Dam in Oregon is the nation's first dam made entirely of roller compacted concrete. The design and construction of this dam are described and special problems...
Biggest Highway Rebuild
The reconstruction of the Wisconsin Interstate 90 and 94 involved 32 miles of 6-lane pavement. Most of the concrete aggregate for the job was recycled concrete pavement and all pavement...
Mixed Use, Mixed Materials
Tabor Center is a $330 million office/commercial/hotel complex in Denver's urban renewal area. The two block site is bisected by a street that had to be kept open during construction....
Mixing Steel and Concrete
For highrise structures, mixed steel-concrete systems are more efficient and cost less than either material alone. The two design approaches are exterior tube structures and core braced...
A Damage Function Using Structural Response Measurements
A new damage function is proposed that expresses seismic damage in terms of the range and number of cycles of plastic deflection experienced by a structure. This and other damage functions...
Damage Model for Buildings Subjected to Earthquakes
A model based on random vibration method is developed for assessing building damage to earthquakes. The damage of reinforced concrete structures is expressed as a linear combination of...
Aesthetics and Design of Prestressed High-Rise Buildings
This paper will address the aesthetics, economic and construction-related advantages of prestressed concrete for high-rise buildings, with an emphasis on the South-East Asia region. While...
The Use and Performance of Seepage Reduction Measures
The utilization and performance of various foundation seepage reduction measures from over 100 dams situated on pervious soils throughout the world has been reviewed. Summary discussions...
Proposed Design Criteria for Composite Steel Deck Slabs
Composite steel deck slabs have continued to gain popularity; today they are one of the predominant means of floor slab construction in most typical buildings. The term 'composite...
Strength of Composite Beams under Seismic Loading
Effective width of a concrete slab of a composite beam is specified in various specifications, but their theoretical backgrounds are obscure. Originally, they must have been specified...
Composite Bridge Design in Germany
A span length between 40 m and 12 m has been regarded as optimal up to the mid-60's for a composite design to compete with prestressed concrete or steel alternatives. With...
Composite Steel Deck Bridge: An Experimental Study
Composite steel decks with steel fiber reinforced concrete (SFRC) were developed, aiming to improve the durability of the deck pavement and to increase the rigidity of the deck plate in...
