Historic Dam Rehab: Handle with Care
A growing number of dams across the U.S. are aging and in need of rehabilitation, but can they be brought up to current codes without compromising their historic integrity? Improved methods...

Geotechnology: An Environment of Change
Today's contaminated materials�soil and water�have been investigated and analyzed by geotechnical engineers for a long time. No other branch of engineering is better positioned,...
Pile Test for Earthquake Repair
Load testing for existing concrete piles was specified as part of a seismic retrofit at the Port of Oakland after the Loma Prieta event. The Port wished to use heavier cranes at cargo...
Anchors in the Desert
The Southwest desert isn't usually thought of as a hotbed of seismic activity, but earthquakes have occurred there. And if Arizona's Stewart Mountain Dam, a double-curvature...
Probabilistic Risk Analysis of TLP Tether Fracture
A stochastic model for fatigue crack growth and final fracture of TLP tethers is formulated. Model updating through in-service inspection is included. The integrity of the cracked tether...
Probabilistic Evaluation of the Performance of Axially Loaded Bored Piles
Probabilistic evaluation of single slender elastic elements, bored piles, in a multi-layered soil system without noticeable displacement of the soils are considered. The numerical analyses...
Seismic Hazard Estimation in the Eastern U.S.
Probable seismic hazard is generally estimated considering five elements: 1) seismicity; 2) source radiation; 3) wave propagation (attenuation); 4) site response; and 5) ground failure....
Largest and Characteristic Earthquakes in the U.S. East of the Rocky Mountains
A new statistical procedure is proposed for the estimation of maximum earthquake magnitude M in intraplate regions. Starting from a historical catalog of events and a seismotectonic classification...
Seismic Ground Motion and Attenuation Relationships
A key element in the assessment of seismic hazard is the estimation of how energy from a given earthquake is affected by crustal structure along the propagation path. There are recognized...
Development of Seismic Hazards Data Base
A seismic hazards data base has been developed as a research tool for the engineering and seismology communities. The data base, which is still growing, currently contains information...
Graphic Demonstration of Seismic Hazards Data Base
A seismic hazards data base has been developed as a research tool for the engineering and seismology communities. The data base presently holds five categories of data, the largest of...
Stochastic Wave Models for Seismic Ground Motion
In order to describe the nature of ground motion arising from a propagating seismic wave, a stochastic wave model has been developed here and an efficient technique for digitally generating...
Seismic Ground Motions for Lifeline Analysis
The spatial variation of seismic ground motions necessary for lifeline analysis is determined from a stochastic source model combined with a substitute system representing the equivalent...
Simple Damage Predictors for Large-Scale Seismic Risk Mapping
Although it is now recognized that there is a risk of moderate seismic activity in the Eastern United States, many existing buildings were not designed for earthquake forces. To evaluate...
Seismic Fragility Analysis of Shear Wall Structures
This paper presents an analytical method to generate seismic fragility curves for shear wall structures. Uncertainties in earthquake motion and structure are quantified by evaluating uncertainties...
Response Modification Factors for Buildings and Bridges
Response Modification Factors (RMF) are often used for the seismic design and the safety evaluation of buildings and bridges. The advantage of using RMF is to account for the nonlinear...
Seismic Response of Structures and Reliability Design
This paper develops a modified SRSS Method which allows a designer to select the reliability that he wishes to realize in each of the various elements of a given structure subjected to...
Wind Vs. Seismic Design
This paper is concerned with the reliability analysis of building structures subjected to multiple natural hazards (seismic and wind in this case) within the framework of contemporary...
