This one-day course is based on the premise that there are unifying seismic design themes that bridge between the earth science and engineering disciplines. At present, the two fields are converging on a capability to develop integrated earth science-engineering models of how a building or other structure at any particular location, or an entire urban region, will behave in future earthquakes. This provides a stimulating goal for discussing work that is currently underway in both fields. Lectures are intended for a mixed audience of earth scientists and engineers, and with both practitioner and academic backgrounds in mind.
Engineers today are conversant with the basic idea of plate tectonics and its role on a regional scale in generating crustal strain that is released as earthquakes. However, recent years have seen many exciting discoveries in seismology that have advanced the state of knowledge considerably further. This course will cover these recent advances and explain the seismic hazard analysis and ground motion modeling capabilities seismology can currently provide to the engineering community.
Seismologists and geologists have long known
that engineers use data on how big and how frequently earthquakes
will occur in a given region to devise building codes, but they
may be unfamiliar with the current generation of code provisions
and analytical tools engineers use to represent ground motions
at particular sites and to propagate those effects through the
components of a structure. Current analytical capabilities in
the engineering field are increasingly able to take advantage
of sophisticated developments in seismology to simulate reality
much more closely than was
possible a decade ago. Engineering experts will explain how they
use geoscience information in their work, with the aim of allowing
earth scientists to better understand the practical aspects of
seismic design, including planning and policy aspects.

9:00 am program begins (refreshments at breaks and lunch included)
5:00 pm program concludes
Registration includes morning and afternoon refreshments, lunch, course notes, and parking in the USC parking lot across Figueroa Steet from the Davidson Conference Center. Directions: From the Harbor Freeway (110) South or North, exit onto Exposition Blvd. and head west towards USC. Turn right onto Figueroa Street and proceed north to the Jefferson/Figueroa Parking Lot on the right, past the Radisson Hotel complex. Tell the attendant that you are attending a meeting at Davidson sponsored by CUREe and SCEC.
Professor Thomas Henyey, University of Southern California and Southern
California Earthquake Center (SCEC)
"The Earth Sciences-Engineering Interface in Seismic
Design: The Importance of Interdisciplinary Interactions"
Keynote Address
Professor Kerry Sieh, California Institute of Technology and SCEC
New Strategies and Technologies for Estimating Regional
Earthquake Potential
Use of improved earthquake catalogs, space-time patterns, clustering,
GPS and SAR, and paleoseismology to estimate regional potential;
"squeezing;" new velocity maps; maximum San Andreas
Fault magnitudes; application of work elsewhere (e.g., Anatolia)
to California.
Dr. Mark Petersen,
California Division of Mines and Geology
Current Seismic Hazard Estimation Techniques
How will our current estimates change as our understanding increases?
Attenuation relationships; site effects; synthetic seismograms
and simulations.
Professor C. Allin Cornell, Stanford University
Towards Probability-Based Seismic Engineering and Design
Seismic events, ground motion intensity, wave forms, and structural
responses and behavior are all characterized by very broad variability.
The evaluation and coupling of all these elements of randomness
and uncertainty in a useful way is a challenge. Practical examples
will be presented of: (2) this seismicity-structural interfacing,
(2) coupling PSHA, nonlinear dynamic analyses, and "dynamic
system capacities," and (3) more simply, the beginnings of
an "LRFD" displacement-based demand-capacity format
under development for the SAC Steel Project.
Dr. Sue Hough,
US Geological Survey
Near-Fault Ground Motions
What do seismologists and engineers know about near-fault ground
motions, and how has our understanding been influenced by the
1994 Northridge and 1995 Kobe Earthquakes? Variability of ground
motions near the seismic source, site characterization, and attenuation
relationships in the prediction of site-specific ground motions.
Professor Thomas Heaton, California Institute of Technology and SCEC
What kinds of advanced ground motion modeling can earth
scientists provide to engineers?
Seismologists can currently provide insights, innovations, and
methods that were only theoretical possibilities a few years ago.
What are the advanced ground motion modeling techniques seismologists
can offer to engineers today?
Dr. Charles Kircher,
Charles Kircher and Associates, Consulting Engineers
Ground Motion Provisions in Building Codes
How do the NEHRP Provisions and the Uniform Building Code (and
the forthcoming Year 2000 International Building Code) define
and treat ground motions for building design purposes?
Professor Helmut Krawinkler, Stanford University
Analytical Methods for Prediction of Seismic Performance
What ground motion information needs to be provided by seismologists,
and how is this information to be used by structural engineers
to predict seismic performance?
Dr. Farzad Naeim,
John A. Martin and Associates
The Use of Geoscience Information in Engineering Design:
Recent Project Examples
How was geoscience information used by the design engineers in
the recent seismic retrofit projects for two major buildings on
the UCLA campus, Royce Hall and Newton Hall?
