Even though the National Bureau of Standards has issued its report on the probable cause of failure in the collapse of the L'Ambiance Plaza. there is room for doubt as to...
Epoxy Update
Epoxy-coated reinforcing steel protects against corrosion if it is used correctly. Several construction practices, such as prescribing the limits on permissible coating damage due to shipping...
Real World Analysis
The structural concepts, seismic analysis and design of five recent highrise structures is presented in this paper. The paper deals with the problem of multistory buildings having Structural...
For Want of a Bolt...
While counterfeit bolt-nut imports make sensational headlines, civil engineers should be more concerned with actual construction problems that have arisen in the past decade. Experts say...
Structural Scale Models: Beyond the Computer
The authors build balsa wood structural scale models to supplement their 3D CADD designs because, for complex framing systems or sites with access problems, the models help clients and...
Stopping the Cracks
It is generally agreed that reinforced concrete in parking garages especially in the deicing salt environment is exposed to unusually hostile service conditions. Deterioration of reinforced...
A Safe Skyscraper For the Seismic City
When completed in late 1989, the 73-story First International World Center will be the tallest office building in Los Angeles. The steel structure of the building was designed to be ductile...
The Precast Pier
For the U.S. Navy's Strategic program, a 1,410 ft long pier was constructed on New York City's Staten Island. The combined efforts of three engineering firms,...
Caissons Skirt a Tunnel
Exchange Place Center is a 490 ft, 30 story office tower built directly over the existing transportation hub in Jersey City, N.J., where trains and buses meet the PATH Tubes that carry...
Computer Assisted Mistakes
The proliferation of computer usage by design engineers will continue to generate change in practice. It will affect the process and production of design. It will affect the relationships...
New Horizons in Construction Materials
While civil engineers have, for centuries, built structures and other physical facilities using whatever materials are available to them, there is always the need for stronger, more durable,...
Source Control of Oil and Grease in an Urban Area
We explored a variety of techniques to remove oil and grease from urban stormwater runoff. Previous work has shown that relatively high concentrations and substantial mass loadings of...
Source Tracing of Toxicants in Storm Drains
Sources of toxic chemicals in storm drains are often difficult to locate and even more difficult to control. Receiving environment chemistry, storm drainage maps, land use information,...
Concrete Pavement Rehabilitation Research Findings
A study to improve the procedures for evaluating and rehabilitating concrete pavements was undertaken in 1985. Field and analytical studies have facilitated a new knowledge and understanding...
Safety Performance Evaluation of 21st Century Appurtenances
A great deal has occurred in the highway safety field in the last 15 years: there have been societal changes which have altered the character of the vehicle fleet; there have been technological...
Preparations for the Future?The European Highway Community
The need for infrastructural capacity in the future in Europe has been investigated by the European Conference of Ministers of Transport - ECMT. The principal traffic considered was international...
Natural Vibrations of Cables in a Flowing Fluid
Cable segments are important components in a wide variety of marine operations. Their nonlinearities are primarily geometric as characterized by large displacements and load-dependent...
Analysis of Hydraulic Impacts at the Tucson Reclaimed Water Recharge Project
The Tucson Reclaimed Water Recharge site has been implemented with increasingly sophisticated calculation methods as data collection efforts advanced. Initial project scoping utilized...
Journal of Aerospace Engineering
The Journal of Aerospace Engineering promotes the implementation and development of space and aerospace technologies and their transfer to other civil engineering applications. Topics of interest include...
Breakwater Breakthrough�Bold New Breakwaters
A new rubble-mound breakwater design is a departure from the conventional approach detailed in the U.S. Army Corps of Engineers Shore Protection Manual. The new concept, called the berm...
