The Hybrid Arena
The University of North Carolina's new basketball arena at Chapel Hill combines steel and fabric in a dome whose design by David Geiger Associates is based on the principles...
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...
Procurement of New Passenger Rail Cars from Japan
In May 1983 the California Department of Transportation (Caltrans) signed a contract with Sumitomo Corporation of America, in which Sumitomo agreed to furnish 63 new stainless steel gallery...
Modelling of the Fracture Process Zone in Rock
There are a number of situations in the fracture mechanics of rock in which linear elastic fracture mechanics (LEFM) concepts are inapplicable or insufficient. Two such situations are...
Lift Bridge looks Like Sculpture
A lift bridge built in 1926 over the U.S. Canal at Kaukauna, Wis. was replaced by a sleek new lift bridge whose sculptured shape encloses all the machinery within welded steel box sections....
Hundreds of Bridges�Thousands of Cracks
In the past 10 years hundreds of welded steel bridges, most of them relatively new, have suffered thousands of cracks due to secondary stresses, that is, the cracks are caused by deflections...
Behavior and Strength of Stub-Girder Floor Systems
The paper presents a detailed evaluation of the behavior and strength characteristics of the stub-girder floor system. This is a composite girder and beam structure that integrates the...
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...
Load-Carrying Capacity and Remaining Life of First-Built Composite Girder Bridge in Japan
Kanzaki Bridge, Osaka, Japan, was the first steel-concrete composite bridge built in 1953 to carry the Osaka Prefectural Road over Kanzaki River. The bridge was removed in 1978 after 25...
Design and Testing of a 400 Ft Span Plate Girder Bridge
The paper describes design features and testing of the Madawaska River Bridge. The bridge is unique in being the longest span plate girder bridge in Ontario, having continuous spans of...
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...
Application of Preflexed Composite Beams to Continuous Bridges
A preflexed beam is a type of concrete encased steel beam of which prestressing has been introduced in the lower flange concrete. Recently, the preflexed composite beams were applied to...
The Eurocodes and Shrinkage in Composite Beams
The two parts of this paper relate to different aspects of design procedures for composite structures of steel and concrete. First, recent developments in the coordination of the eight...
Experimental Investigation of Composite Rigid Frames
According to the series of tests conducted by the authors on composite rigid frame models, the compressive principal stress in the steel web plate at the corner panel was considerably...
A History of Adhesive Bonded Composite Members
The history and development of adhesive bonding in composite members is traced. Two forms of composite members are explained. Research from different parts of the world is compared. Applications...
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...
Recent Research on Composite Structures for Building and Bridge Applications
Continuing research has been carried out at Lehigh University on composite structural members, joints, and overall systems. This paper summarizes the results of research on four selected...
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...
