Comparison of Code-Based Design Spectra and Site-Specific Response Spectra in San Francisco
This paper presents seismic site response studies performed in 2016 and 2017 for two projects in San Francisco, California, carried out with San Francisco Public Works. The design rock input motions developed for the projects are also discussed, which are used by a companion paper on the structure-soil-structure interaction (SSSI) analyses. With a focus on how the surface response spectra compare with the ASCE 7-10 code-based design response spectra, as well as the resulting reduction of design spectral amplitudes allowed per the design code by performing a site-specific study, the findings of the study indicate that the code minimum spectra tend to be conservative in the short period range for soft clay sites. One of the project sites has the underlying Franciscan Complex bedrock sloping considerably across the project area, which results in different site periods at either end of the proposed development. It was found that it is important to consider multiple soil models to represent the varying site periods.
