Development of Geographical Information System (GIS) for Seismic Hazard Study of Charleston, SC
One of the most prominent areas of seismicity in the eastern U.S. is near Charleston, SC. The 1886 Charleston earthquake (M=7,5) and liquefaction evidence from at least five prehistoric...
CALTRANS Seismic Hazard/Risk Map and Proposed GIS Applications
The California Department of Transportation (CALTRANS) considers earthquake effects in planning, design, and construction of their structures. Obviously, CALTRANS has to respond to damaging...
A Prospect for Liquefaction Hazard Evaluation Using GIS
A brief description of a recently developed methodology to evaluate liquefaction hazard at a site is presented. In this method, uncertainty and scatter in the data are considered rigorously....
A Geotechnically-Oriented GIS for Seismic Hazard Mapping
A geotechnical GIS has been configured by the California Department of Conservation's Division of Mines and Geology for the purpose of designating seismic hazard zones as mandated by recent...
State of the Art in Spatial Data Transfer: FIPS 173
This paper provides an overview of Federal information processing standard (FIPS) 173. FIPS 173 is a comprehensive spatial data transfer standard that provides solutions to the problem...
Potential Role of GIS in Geotechnical Earthquake Engineering Studies at U.S. Army WES
The U.S. Army Corps of Engineers (USACE) was one of the original developers of Geographic Information Systems (GIS) and continues to be active in related research (U.S. Army Engineer Construction...
Accessibility of Geotechnical Earthquake Engineering Data and the Need for Data Storage and Dissemination Standards
Ease of data access and data standards are two issues critical to the success of GIS technology when applied to earthquake hazards research problems that require geotechnical engineering...
Towards a Common Data Exchange Format Between Geographic Information Systems
To make their respective geographic information systems (GIS) software packages more useful to the user community, the GIS software vendors have steady added various database translators...
Taking the Pain out of the Punch List
Lengthy punch lists mean trouble for everyone involved, from the owner to the designer to the contractor, but the punch list doesn't have to be long and it doesn't...
The Proof is in the Pavement
A technique known as statistical quality assurance (SQA) lets DOTs quantify pavement quality by setting statistical guidelines for the work they will accept. SQA is a distinct departure...
RCC: Rehab Results
Thirty dams have been modified with roller compacted concrete in order to provide additional spillway capacity and for safe overtopping of embankment dams. In the national dam safety inspection...
DART'S ASAP EIS
An environmental impact statement that takes several years to complete can demoralize the staffers behind a transportation project and reduce public support for the effort. In a hurry...
Plastic Potential
Some 220,000 tons of epoxy-coated steel has been used in the construction of bridge decks since 1987, but some have raised questions about its long-term durability. New materials for prestressing...
Detecting Leaks in Geomembranes
A field-tested leak-location survey, now commercially-available, can provide construction quality assurance or solve a leakage problem in lined landfills, impoundments or tanks. A liner...
Bonded Tendon Debate
Bonded tendons�currently banned in bridge construction in the United Kingdom because of corrosion concerns�are getting a bum rap, says the author. Corrosion protection details of most...
Building the SSC: A Texas-Sized Challenge
Assuming it survives politically, the $8.25 billion Superconducting Super Collider could bring major new discoveries in the world of physics. For civil engineers, the Texas megaproject...
Steel Exoskeleton Defines Architecture
The Hotel de las Artes multi-use complex in Barcelona, Spain consists of a luxury hotel/apartment tower, a commercial office building, retail, parking and other amenities. The most prominent...
Nondestructive Testing Role in Repair and Rehabilitation of Concrete Structures
Nondestructive testing (NDT) methods are increasingly being used to assess the condition of structural concrete. The paper discusses applications of NDT methods for forensic investigation...
Assessment and Repair of Fire-Damaged Concrete Structures
Concrete, even though it may be the most fire-resistant of all the major building materials, can be damaged by fire. Seldom does even a major fire cause total destruction, however, most...
Evaluation and Repair of Unbonded Post-Tensioned Concrete Structures
As with other forms of infrastructure, there is an ever increasing need to repair and strengthen unbonded post-tensioned concrete structures. Repairs may be necessitated for a variety...
