Achieving enhanced regional disaster resilience with respect to strong earthquake shaking requires a multi-faceted approach involving designing more resilient infrastructure, addressing deficiencies in existing infrastructure, and developing tools for accelerating post-disaster recovery. Achieving disaster resilience in this context goes beyond targeting the traditional life-safety performance objectives for structures and extends to implementing strategies for limiting damage during earthquakes. Unfortunately, our leading standardized and non-standardized design, evaluation, and retrofit methodologies have only begun to progress towards improved seismic performance and recovery times, and are stymied but several challenges; the most outstanding of which being the lack of reliable decision-oriented simulation capabilities. The proposed project intends to fill this critical simulation gap for reinforced concrete columns subjected to severe earthquake demands. The proposed simulation tools will usher a new era of decision-oriented tools by going beyond the traditional force-deformation computational space to deliver critical engineering data that enable informed decisions for enhancing seismic resilience. The proposed tools will deliver metrics for damage type and extent, for residual capacities applicable to post-event recovery evaluations, and for retrofitted capacities in support of retrofit decisions. The tools will also be instrumental in reducing the costs associated with enhancing the resilience of concrete buildings, as they will be developed to explicitly simulate all strength degradation modes up complete loss of strength, thus allowing engineers to assess the impact of loss of one or more columns on the overall stability of the system and make full use of structural redundancies that can greatly enhance structural seismic performance and reduce rehabilitation needs. Thorough the advanced metrics, the proposed simulation tools will greatly facilitate and increase the effectiveness of the decisions structural engineers make in targeting enhanced resilience of concrete buildings to earthquake hazards. Outcomes will be seismic resilience enhancement at lower life-cycle costs, which will results in more existing buildings that pose a collapse risk to be retrofitted, and increasing numbers of new designs to go beyond minimum life-safety goals to enhanced damage resistance. consequently, communities in seismic risk areas will benefit in the immediate as building seismic performance is increased, and after an event through fewer deaths, lower repair costs, and shortened recovery periods.
