Three-Dimensional Analysis Model for Complete Masonry Buildings
For the predictive and diagnostic analysis of the complete nonlinear response of masonry buildings to seismic load input, a 3-D finite element model is under development at UCSD. The model,...

New Views for Modeling Dynamic Response of URM Buildings
Various computational models are used to depict seismic response of an unreinforced masonry building that was subjected to the 1989 Loma Prieta Earthquake. The worthiness of various analytical...

Seismic Design of Steel Beam-to-Box Column Connections
This paper is a study of the ductility requirements of steel beam-to-box column connections using the bolted beam web and welded beam flange details. Since the beam moment at the connection...

Mapping Structural Damage to Monetary Damage
Earthquake damage estimation/prediction is still an area which requires expertise and judgment of the experts in the field. Making the predictions/estimates more accurate is an area of...

A Prototype Expert System for Rapid Visual Screening of Seismically Hazardous Buildings in California
A rapid visual screening expert system, California Rapid Building Seismic Evaluation Expert, was developed to enable efficient and effective identification of seismically hazardous buildings...

Fatigue Reliability of Structural Systems Under Earthquake Loads
The authors have develop a methodology for calculating the expected low-cycle fatigue damage in structural components subjected to brief nonstationary random loads. The methodology is...

Analysis of the Seismic Records of a Suspension Bridge
A well-instrumented suspension bridge in Los Angeles, was shaken by the October 1, 1987 Whittier earthquake (ML = 5.9). This study addresses the...

Loma Prieta Response of an Eccentrically Braced Tall Building
Acceleration response records obtained during the October 17, 1989 Loma Prieta earthquake [Ms = 7.1] from the 47-story, eccentrically braced Embarcadero...

Liquefaction Evaluation by Seismic Potential Procedure
Empirical procedures in common use for liquefaction evaluation employ information from a variety of sources in order to evaluate whether or not a site will undergo liquefaction. The information...

Photogeologic Reconnaissance of X-Tunnel at Little Skull Mountain
An underground structure known as X-tunnel was investigated for the viability as an underground deep based missile system that included the capability to maintain survivability following...

Science Education Beyond the Classroom
The Yucca Mountain Site Characterization Project (YMP) sponsors a variety of classroom-oriented projects and activities for teachers who request them. Also available, though, are extra-curricular...

Field Investigation of Mining-Induced Seismicity on Local Geohydrology
Hydraulic response of the rock mass due to earthquakes is one of the concerns in the assessment of the long-term performance of a repository. Studies performed by other researchers indicated...

Earthquakes and Nuclear Waste: A Lesson in Media Relations
The Little Skull Mountain earthquake on June 29, 1992 marked the beginning of a challenging period for the U.S. Department of Energy's (DOE's) Yucca Mountain Site Characterization Project's...
