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...

Mixed Systems: Past Practices, Recent Experience, and Future Direction
A comparison is made between composite column capacities derived from the authors procedure utilizing the ACI (America Concrete Institute) code requirements, and previously published semi-empirical...

SRC Elevated Station Structures for New Bullet Trains
SRC Steelframe reinforced concrete structures were utilized on several station buildings for the Japanese National Railways bullet trains. This paper presents an outline of the dimensions...

Recent Developments in Mixed Steel-Concrete Systems
Mixed steel-concrete systems have emerged into a well established new system that can be used as readily as either steel or concrete systems for high-rise buildings. Mixed systems offer...

Strength of Biaxially Loaded SRC Columns
The paper presents the results of an experimental study on the elasto-plastic behavior of 'Steel reinforced concrete (SRC)' columns subjected to biaxially eccentric...

Bond Check for Concrete-Filled Steel Tubular Columns
In order that a concrete-filled steel tubular column may display a maximum bearing capacity for sustaining the long-term vertical loads transferred from the steel beams to the steel tube...

Beam-to-Column Connection of a Composite Structure
Composite structures can exhibit excellent performance against seismic force, and fire safety as well. However, the traditional steel reinforced concrete (SRC) system or concrete encased...

Bond Stress of Embedded Steel Shapes in Concrete
This paper describes an investigation into the bond stress developed between steel shapes and reinforced concrete when the concrete is lightly stressed. A brief discussion of previous...

Recent Developments for Composite Buildings in Japan
Research work and construction practice of composite steel and reinforced concrete structural systems in Japan are reviewed, based on the data gathered by the working group of the Architectural...
