Box Segmentals: Refining Design
Officials at the Florida Department of Transportation (FDOT), which has built more precast concrete segmental box girder bridges than any other state, say their troubles with that design...
Cautious Risk Taking
Traditionally, the design engineer could bear virtually unlimited liability for design failure. Now he is less vulnerable. The concept is less than 20 years old, but since the early 70s,...
Post-Tensioned Transportation
Post-tensioned highways are relatively new. U.S. 220 near Altoona, Pa. has the first major installation in the country. There two miles of pavement are continuous concrete panels, each...
Assessing Site Assessments
Laier and Sibley contend that the growth in environmental site assessments, fast becoming routine in many types of real estate transactions, could create a windfall market for engineering...
Grouting Trends
The grouting industry is discussed and North American practice compared to European practice. There has been more innovation in this field overseas, but there have also been failures....
Unbonded Performance
Unbonded single strand tendons have been used in the U.S. for about 30 years. In a small number of buildings, strand corrosion failures have occurred. Although it is clear that post-tensioning...
New Roof for an Aging Temporary
The wartime temporary design of a 1942 industrial building justified use of green timber for its roof trusses and higher than usual allowable design stresses. Some 45 years later, a new...
They're Coming to America
Foreign firms have been involved in the U.S. construction market for decades but their role has been small. Foreign contractors lacked information and communication skills and they believed...
Building the Perfect Playpen
Today, the stadium itself has become almost as important as the teams playing the game. Eschewing the standard cookie-cutter design of the 60s, clients and owners generally have a laundry...
The Race for Smart Cars
Prendergast describes the technological elements involved in Intelligent Vehicle/Highway Systems (IVHS), current programs in Europe, Japan and the U.S. aimed at implementing IVHS systems,...
High-Strength Concrete: Weighing the Benefits
Russell, Gebler and Whiting describe the properties of high-strength concretes, the current state of knowledge on freeze/thaw effects, and procedures for batching, mixing, transporting,...
Rx for Dam Repair
Bernard asserts the growing importance of maintenance to extend the service life of dams as more and more of them reach or exceed their design lives. He describes renovations to Easton...
Isolated Examples
The technology of seismic isolation, also known as base isolation, is being used to protect the contents and occupants of a building as well as its structure. Isolators are led-rubber...
Seismic Codes:Preparing for the Unknown
Few eastern communities follow seismic codes because few communities view earthquakes as a risk. Although California-sized quakes have hit Charleston, St. Louis, they've done...
Screaming Structures
As any designer of roller coasters will tell you, civil engineering principles put the thrills and screams into roller coasters. There are two basic differences between roller coaster...
Creative Application of Materials Engineering
Society's demand for an aesthetically pleasing and safe constructed environment, along with the construction industry's higher and higher costs, dictate that...
Automated People Movers II
New Links for Land Use?Automated People Mover Opportunities for Major Activity Centers
This Proceedings, which consists of 94 papers presented at the Second International Conference on Automated People Movers (APM's) held in Miami, Florida on March 13-15, 1989,...
Affordable Housing
a Challenge to Civil Engineers
This conference proceedings, which consists of 25 papers presented at the National Conference on Affordable Housing held in Miami, Florida on December 6-8, 1989, discusses ways that the...
Post-Audits of Environmental Programs and Projects
This is the proceedings of a session at the ASCE Convention, New Orleans, October 1989. Post-audits include evaluation, assessment, and audit of the effects, both intended and unintended,...
Resilient Moduli of Soils
Laboratory Conditions
Historically, structural pavement design has been based on static testing techniques, such as the CBR. More recently, the profession has placed increased emphasis on repeated load testing...
