Novel Framework for Resilience Assessment of Tall Buildings

Terzic, Vesna / Kolozvari, Kristijan

This study presents a novel, newly developed framework for resilience assessment of tall buildings and demonstrates its application on a 42-story PEER TBI RC core wall building. A nonlinear model of the building is created in OpenSees using a new three-dimensional model for RC walls. Building seismic response is obtained for three seismic hazard levels corresponding to SLE, DBE, and MCE-level events. Based on the results of nonlinear analyses, building damage is evaluated using FEMA P-58 tools, while the building recovery process is evaluated using a sophisticated recovery model. Building seismic performance obtained using new structural and recovery models suggest that the post-earthquake functionality of the tall building is primarily governed by the structural subsystem. For example, for a DBE-level event, the building’s functionality will be fully impaired due to significant damage to slab-column connections and shear walls; the building will regain its functionality in 8 to 13 months.
