A Tale of Two Laboratories
Two unusual research centers are built with the materials that will be studied in them, but the similarities end there. GE Plastics' $10 million Living Environments concept...
Protection of Wood Designs in Adverse Environments
Engineers and architects are becoming increasingly aware of the risks of poor wood design practices and the benefits of using wood properly. This paper addresses biological factors that...
Repair of an Improperly Detailed Masonry Facade: A Case History
The masonry facade of an 18-story condominium building was constructed with an inconsistent pattern of shelf angle supports, marginal lateral restraints and without any horizontal control...
Building Joint Movement
Moisture leakage in masonry claddings occurs not only through copings and facial separation cracks, but also through failed sealant joints in the veneer. The factors affecting joint movement...
Three Tools for Design Test Bed Analysis
Three analytical tools are outlined for use in design test bed work focusing on the design/production interface. The tools are substitution analysis, coupling analysis, and value chain...
More Than a Public Hearing
Too often, required community input is reduced to the sometimes dreaded public hearing. Many formal public-involvement programs are comprised of no more than this minimal, yet essential,...
Prospects for International Engineering Practice
International trade is growing in construction products and services. It is stimulated by international efforts to reduce technical barriers to trade and the formation of a single European...
Commentary on Building Code Requirements for Masonry Structures (ACI 530-88/ ASCE 5-88) and Commentary on Specifications for Masonry Structures (ACI 530.1-88/ ASCE 6-88)
Seismic Surgery
The authors describe the installation of seismic isolators in the columns of an eight-story concrete building in Seal Beach, Calif., which serves as Information Systems Center for Rockwell...
U.S. Landmarks: Handle With Care
Landmarks are treated with kid gloves during restoration, but striking a balance between costs and aesthetics is difficult. In addition to structural integrity, original construction methods...
Seattle Swing
The swing bridge has long been out of favor in the U.S. because of the navigational hazard presented by mid-channel pivot piers. A consortium of engineers is updating the design to a state-of-the-art...
Upgrading Antique Sewers
In a $35 million, four-year program, the Massachusetts Water Resources Authority (MWRA) completely restructed the pumping system serving the sewers under East Boston, Chelsea, Revere and...
Projects That Point
This is only a small sampling of what we can expect inthis decade. An $80 million kiln at Port Arthur, Tex., reportedly the largest of its kind in the U.S., handles bulk solids and sludges....
Designing in Circles
Round buildings are a popular�but sometimes expensively perceived�design choice. With careful engineering and planning, they can offer a creative, cost-competitive option. They add another...
The Invisible Engineer
For all their contributions to society, engineers have worked largely behind the scenes, seldom remembered in the dedication ceremonies of bridges and tunnels and skyscrapers. Several...
Taming Structural Vibrations
Vibration is a common problem in buildings that contain large spaces and long spans, especially gymnasiums and dance studios. Research shows that people respond more adversely to continuous...
Replacing an Urban Foundation
Baltimore's new subway extension will pass close to a 6-story reinforced concrete building near the Inner Harbor. Its timber piling foundation was threatened by the dewatering...
Aussie Steel
The 50-story Chifley Square Building being built in Sydney will be the tallest Australian steel building. Scheduled for completion in June 1992 at a cost of $310 million, it will house...
Quality in the Constructed Project
