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...
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...
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...
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...
Seismic Design of Multi-Story, Wood-Framed Buildings
The seismic design and analysis of wood-framed structures is relatively simple; however, the challenges that present themselves within this design medium are shear and overturning force...
Driven Then Pushed Minicone Tests in a Sand Chamber
For a general knowledge on the Standard Cone Penetrometer test and its uses the reader is referred to the work of Briaud and Miran (1991). For this study (Khalaf and Briaud, 1992) a smaller...
Lateral Loading Curves from Pressuremeter Tests
The large drilled shafts for the proposed Klamath Falls Bridge, which are to be founded in diatomaceous silts, were to be designed to withstand earthquake induced large cyclic loading....
Piles for Marquette University Math Building
This paper presents a comparison of static pile capacity predictions using CPT cone resistance results with results of a test pile program and production pile driving. Pile capacity prediction...
Evaluation and Monitoring of Pile Performance Using Dynamic Measurements in Supporting Offshore Structures
The installation of offshore platforms into deeper waters and new environments is accompanied by an increasing uncertainty in the structure response, foundation design and performance....

The Hazard In Using Probabilistic Seismic Hazard Analysis
Probabilistic seismic hazard analysis has been used extensively for major dams; nuclear power plants; liquefied petroleum gas installations; repositories for dangerous wastes; sensitive...
Seismic Remediation for Earth Dams
Over the last 30 years or so, new analysis methods and case histories of dam performance in earthquakes have significantly changed our understanding of the severity of the earthquake hazard...
Stability of Rock Armour Under Random Wave Attack: Performance of Non-Standard Rock Shapes and Gradings
Quarried rock is frequently used to protect coastal and shoreline structures against wave attack. Armour rock specifications generally exclude rock that is rounded or tabular, and gradings...
RCC for Rehabilitation of Dams in the USA-An Overview
The use of roller-compacted concrete (RCC) has rapidly become a powerful new tool in the USA for engineers involved with the rehabilitation of existing dams. Starting in 1980, RCC has...
Final Design and Construction of Gibraltar Dam Strengthening
The results of a 1983 safety evaluation of Gibraltar Dam indicated that the dam did not meet seismic safety standards. A remedial scheme involving the addition of a roller compacted concrete...
Dams Going Safely over the Top
Many older dams can't pass updated design floods without overtopping the embankment crest. Conventional upgrade methods, enlarging spillways or raising crests, are expensive....
