This paper presents the Intelligent Circular Resilience (ICR) framework as an innovative solution to improving seismic resilience and disaster risk reduction in heritage buildings. The study focuses on a century-old religious monument located in Lima, Peru, a region considered to be of high seismic hazard. The ICR approach integrates Structural Health Monitoring (SHM) with Digital Twin (DT) systems, enabling a dynamic connection between the physical and virtual worlds. SHM provides real-time data on the building’s structural performance through strategically placed sensors, while DT systems generate simulations that predict how the structure behaves under earthquake events. This integration allows for a comprehensive analysis of structural health and enables the design of effective resilience strategies. The core of the ICR framework involves six key steps: Building System Characterization, Virtualization, Data Retrieval and Sensor-Based Analysis, DT Model Updates, Results and Reports Generation for DT, and Duality Feedback. For this study, finite element-method (FEM) analysis was applied using advanced analytical software tools such as 3DEC and SAP2000 to conduct both modal and time-history analyses. These analyses were performed on 34 seismic ground motion records, simulating the dynamic response of the building. The results of the FEM analysis identified vulnerable zones in the structure and established threshold limits for triggering early warning systems. The use of FEM models within the ICR framework allowed for a precise assessment of the building’s resilience, highlighting critical areas that require intervention and maintenance. The findings demonstrate the ICR framework’s effectiveness in improving seismic performance by offering a holistic and adaptive approach to monitoring and managing heritage structures. This methodology enables building managers to optimize maintenance strategies, reduce long-term costs, and ensure the preservation of historically significant structures while extending their life cycle in seismic regions.

摘要

This paper presents the Intelligent Circular Resilience (ICR) framework as an innovative solution to improving seismic resilience and disaster risk reduction in heritage buildings. The study focuses on a century-old religious monument located in Lima, Peru, a region considered to be of high seismic hazard. The ICR approach integrates Structural Health Monitoring (SHM) with Digital Twin (DT) systems, enabling a dynamic connection between the physical and virtual worlds. SHM provides real-time data on the building’s structural performance through strategically placed sensors, while DT systems generate simulations that predict how the structure behaves under earthquake events. This integration allows for a comprehensive analysis of structural health and enables the design of effective resilience strategies. The core of the ICR framework involves six key steps: Building System Characterization, Virtualization, Data Retrieval and Sensor-Based Analysis, DT Model Updates, Results and Reports Generation for DT, and Duality Feedback. For this study, finite element-method (FEM) analysis was applied using advanced analytical software tools such as 3DEC and SAP2000 to conduct both modal and time-history analyses. These analyses were performed on 34 seismic ground motion records, simulating the dynamic response of the building. The results of the FEM analysis identified vulnerable zones in the structure and established threshold limits for triggering early warning systems. The use of FEM models within the ICR framework allowed for a precise assessment of the building’s resilience, highlighting critical areas that require intervention and maintenance. The findings demonstrate the ICR framework’s effectiveness in improving seismic performance by offering a holistic and adaptive approach to monitoring and managing heritage structures. This methodology enables building managers to optimize maintenance strategies, reduce long-term costs, and ensure the preservation of historically significant structures while extending their life cycle in seismic regions.
