Description:
This research introduces a novel approach to quantify and model the post-hazard performance of reinforced concrete (RC) shear walls under multi-hazard scenarios. Particularly, this study utilizes surface crack patterns and links them to the post-hazard load-displacement behavior of RC shear walls. The combination of two dilemmas of climate change-driven multi-hazard events and the limitations of existing codes have created a need for a more robust approach to structural assessment. The novelty of this research lies in its fundamental shift from traditional, "as-designed" structural models to a novel "as-damaged" approach that incorporates real-world observations of damage, specifically surface crack patterns, into the assessment of post-hazard performance. This research bridges the knowledge gap by integrating graph theory, numerical modeling, and crack-pattern-based models to provide a more accurate representation of the post-hazard as-damaged state of the structure. The outcomes will advance the field of performance-based design by providing new insights into the cumulative impact of multiple hazards and improving post-hazard resilience assessments.
