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...
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...
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...
Composite Columns?Design and Examples for Construction
The new German standard DIN 18806, part 1 gives the rules for the design of composite columns. The general method, taking into account all the inhomogeneties of the two materials steel...
Composite and Mixed Construction in Czechoslovakia
Various composite and mixed systems have been used in Czechoslovakia. Special attention is focused on design methods, effective construction, and material savings. Current developments...
Seminar Summary and Research Needs
All the papers presented in the technical sessions of the seminar are summarized and, in some cases, commented upon. The needed research in composite and mixed construction is described....
Binding and Bonding Concrete to Composite Columns
Composite interaction between concrete encasement and structural steel shapes is limited unless lateral ties and/or mechanical attachments insure such interaction until desired strength...
Timber Bridge Decks
The portion of the nation's 500,000 bridge decks that are made of timber has been declining for years, as the old timber ones on secondary road bridges are rebuilt, in most...
High Strength Steel
A
A Road to Recovery
Inspections of the Golden Gate Bridge revealed that the bridge had localized corrosion near its expansion joints, corrosion of its reinforcing steel, and was severely contaminated with...
Risk Analysis for Ship-Bridge Collisions
The authors have developed a propriety software package which has been successfully used to perform risk analyses for several high-level bridge structures across major waterways in coastal...
Coping with Litigation
Engineers should learn legal philosophy, even though it seems unrelated to traditional technical practice. Monitoring changes in legal theory that may increase engineers'...
Floating Bridge for 100 Year Storm
In 1979 the west half of the Hood Canal Floating Bridge, built in 1960, in Seattle broke up and sank during a storm that lasted eight hours with winds of 80 mph and gusts over 100 mph....
Record Bridge Replacement
Jacks Run Bridge had to be rebuilt in one year instead of the usual two to three. So the Pennsylvania Department of Transportation spearheaded the quickest replacement of a major bridge...
Bridging Twin Ports
The Major Richard I. Bong Memorial Bridge, part of U. S. Highway 2, connects harbors at Duluth, Minn. and Superior, Wisc. The new highway link was designed to relieve congestion on nearby...
Who Should Design Bridges?
For many years Design-Build-Proposals have been common practice in Europe (except in the UK). Structures in these countries are 20% more economical than similar projects in the U. S.,...
The Impact of the I-664 Bridge-Tunnel Crossing on Sedimentation
A sedimentation evaluation was made of the proposed I-664 Bridge-Tunnel complex across the James River, Virginia. This paper briefly describes the procedures used and the results obtained...
Investigation of Design Criteria for APM Guideways
Designers have relied mostly on the provisions of the American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications for Highway Bridges. Sometimes...
Shear Stresses in Composite Masonry Walls
The behavior of composite masonry walls subjected to inplane loads is a subject that has received little attention during the last few years. The small amount of experimental and analytical...
Nine Years' Service with Deep Polymer Impregnation
A test installation of deep polymer impregnation was applied to a heavily traveled bridge deck in Bethlehem, Pennsylvania, in 1975. The deep polymer impregnation process involved drying...
