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.
