	             CSMIP DATA INTERPRETATION OPPORTUNITY

The California Strong Motion Instrumentation Program (CSMIP) of the
California Department of Conservation's Division of Mines and Geology plans
to fund three data interpretation projects for the analysis and utilization
of strong-motion data.  These projects are intended to further the
understanding of strong ground shaking and the response of structures, and
to increase the utilization of strong-motion data in improving seismic
design codes and practices.  Proposals for projects of one year duration,
and $70,000 and $100,000 maximum budget level for each project are solicited
for the investigation categories of Ground Response and Building Response,
respectively.  Proposals are due on May 12, 1998.  The data interpretation
topics are:

1. Ground Response - Site Response Studies:

Analyze ground response records corresponding to different levels of shaking
from recent California earthquakes to investigate site amplification
effects.  Perform data analysis to verify/characterize nonlinear site
amplification effects versus linear elastic site amplification.  Study the
amplitude dependence and the level and frequency band of possible nonlinear
effects at specific site conditions.  Evaluate the significance of nonlinear
effects and how site amplifications derived from data of small magnitude
events can be applied to site amplifications during large earthquake with
possible impact to seismic codes.

2. Ground Response - Vertical Ground Motion:

Study the characteristics of observed vertical ground motion in the areas of
strong shaking and the effects of vertical ground motion on the response of
structures.  Investigate correlations of vertical and horizontal ground
shakings including the frequency content and the ratio of vertical to
horizontal ground motion spectra.  Identify the characteristics of the


vertical ground motion that significantly affect the response of structures.
Verify or develop improvement to the provisions in seismic design codes.

3. Building Response - Steel Frame Buildings:

Perform case studies of four steel buildings for the purpose of improving
seismic design codes and practices, using the recorded response and observed
performance from the 1994 Northridge earthquake.  Explain the recorded
motion and observed damage using linear and/or nonlinear techniques.
Evaluate current building design guidelines and practices considering the
implication of strong-motion records and observed performance during the
Northridge earthquake.
