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...
Highway Safety
At the Crossroads
The papers in this book were presented at the ASCE Specialty Conference, Highway Safety: At the Crossroads, held in San Antonio, Texas, March, 1988. Among the topics covered are: assessment...
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...
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,...
Safety on 21st Century Highways
Consistently high geometric design standards, adequate pavement skid resistance, drainage and markings, and appropriate signing, delineation and lighting all reduce the potential for driver...
Roadside Safety Design for the Micro-Mini Vehicles
This paper summarizes the results of a study to evaluate the impact performance of widely used roadside safety elements for a 1,500 lb vehicle and to identify potential modifications that...
CARTS: Next Generation in Vehicle Safety Research
The California Automotive Research Test Site (CARTS), is a new joint test facility for use by the California Department of Transportation (Caltrans) and the University of California at...
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...
Future Driver and Vehicle Characteristics and Their Influence on Highway Design for Safety
Both driver and vehicle characteristics are changing, and these characteristics will continue to change into the 21st century. The purpose of this paper is to identify the major changes...
Safety and Operations Related to Geometrics for 21st Century Highways
Highways designed for the next century must reflect the knowledge gained from research on safety and operations conducted over the last 20 years. Assuming that recent trends toward emphasis...
Traffic and Safety Research Payoffs
This paper reviews contributions to the practice of transportation engineering by research in the traffic and safety area. Brief overviews are provided in the area of traffic operations...
Research for 21st Century Highways
The national highway community is looking into the 21st Century to anticipate the needs that will be placed on highways over the next 3 decades. The view suggests that new technology will...
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...
