Nonlinear Response History Soil–Structure Interaction Studies on UCSF Health Helen Diller Hospital Building
The ASCE/SEI 7‐16 standard contains prescriptive provisions for soil–structure interaction (SSI). However, SSI is rarely incorporated into nonlinear response history analyses, particularly in performance‐based seismic design. This paper examines the seismic response of the $4.3 billion University of California, San Francisco Health Helen Diller Hospital Building, explicitly considering SSI effects. The 258‐foot‐tall structure comprises 15 aboveground levels and two basement levels and is supported by a pile foundat …
