Vibration and dynamic strain measurements were obtained using accelerometers and piezo-resistive strain gauges, capturing low-magnitude dynamic strains during operational vibrations. 3D-LiDAR scanning and Ultrasonic Pulse Velocity (UPV) tests captured the bridge's as-is geometry and modulus of elasticity. The resulting detailed 3D point cloud model revealed the structure's true state and highlighted discrepancies between the as-designed and as-built conditions. Dynamic properties, including modal frequencies and shapes, were extracted from the strain and acceleration measurements, providing critical insights into the bridge's structural behavior. The neutral axis depth, indicating stress distribution and potential damage, was accurately determined. Good agreement between vibration measurement data and the as-is model results validated the reliability of the digital twin model. Dynamic strain patterns and neutral axis parameters showed strong correlation with model predictions, serving as sensitive indicators of local damage. The baseline digital twin model and measurement results establish a foundation for future bridge inspections and investigations. This study demonstrates the effectiveness of combining digital twin technology with field measurements for real-time monitoring and predictive maintenance, ensuring the sustainability and safety of the bridge infrastructure, thereby enhancing its overall resilience to operational and environmental stressors.</div></div>","PeriodicalId":101077,"journal":{"name":"Resilient Cities and Structures","volume":"4 3","pages":"Pages 48-66"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144858424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The growing interest in impacts beyond physical damage and community resilience has spurred a surge in literature on economic modeling methodologies for estimating indirect economic impacts of disasters and the recovery of economic activity over time. In this review, we present a framework for categorizing modeling approaches that assess indirect economic impacts across natural hazards and anthropogenic disasters such as cyber attacks. We first conduct a comparative analysis of macroeconomic models, focusing on the approaches capturing sectoral interdependencies. These include the Leontief Input-Output (I/O) model, the Inoperability Input-Output Model (IIM), the Dynamic Inoperability Input-Output Model (DIIM), the Adaptive Regional Input-Output (ARIO) model, and the Computable General Equilibrium (CGE) model and its extensions. We evaluate their applicability to disaster scenarios based on input data availability, the compatibility of model assumptions, and output capabilities. We also reveal the functional relationships of input data and output metrics across economic modeling approaches for inter-sectoral impacts. Furthermore, we examine how the damage mechanisms posed by different types of disasters translate into model inputs and impact modeling processes. This synthesis provides guidance for researchers and practitioners in selecting and configuring models based on specific disaster scenarios. It also identifies the gaps in the literature, including the need for a deeper understanding of model performance reliability, key drivers of economic outcomes in different disaster contexts, and the disparities in modeling approach applications across various hazard types.</div></div>","PeriodicalId":101077,"journal":{"name":"Resilient Cities and Structures","volume":"4 3","pages":"Pages 1-14"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144653135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within these efforts and frameworks, less attention has been paid to the post-earthquake recovery time of buildings and communities, thus ignoring the significance of reaching a desired recovery state (e.g., functional recovery) within a specified time frame. To overcome this limitation, this study estimates post-earthquake recovery times and uses them as one of the decision variables in multi-criteria identification of optimal retrofitting of an existing RC building. The case-study building is representative of the Italian school buildings constructed between the 1960s and 1970s and was analysed under two seismic hazard levels (moderate and high). Following the identification of the main structural deficiencies of the as-built structure through nonlinear static analyses, four seismic retrofit measures were selected. Then, the earthquake-induced downtime of each of the four retrofitted building configurations was assessed, analysing the different recovery times as a function of the seismic hazard level and the recovery state. A downtime-based metric, namely the expected annual downtime, was introduced as decision variable within an available multi-criteria decision-making framework to include the impact of downtime, rank the four retrofit measures and identify the preferable one.</div></div>","PeriodicalId":101077,"journal":{"name":"Resilient Cities and Structures","volume":"4 3","pages":"Pages 15-29"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144653136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the critical need for quantitative assessments of both flood damage and the effectiveness of flood mitigation measures, most existing studies have focused on isolated aspects of flood risk. Only a very limited number of studies have comprehensively integrated hazard mapping, hydrodynamic simulations, and economic damage estimations to evaluate the real-world impact and effectiveness of flood mitigation measures (FMMs). This study presents a multi-method approach to evaluate the performance of such established structural FMMs. Initially, hazard assessments for two selected case study areas, the Colombo Metropolitan Area in Sri Lanka and Auckland, New Zealand, two flood-prone cities with contrasting geographical contexts. Flood inundation mapping for the Madiwela South Diversion, Colombo, Sri Lanka, was performed using hydrodynamic modeling to demonstrate the reduction in flood inundation area and depth after the implementation of the measure, considering six (6) design return periods (RPs). Subsequently, tangible and intangible property damage estimations for “without FMMs” and “with FMMs” were evaluated to identify the benefit of responding to flood conditions, utilising a vulnerability-based economic analysis. In addition to damage estimations, the study adopts a novel approach by conducting an investment viability analysis to find the Benefit-to-Cost ratios and Net Present Value of nine (9) selected FMMs implemented by Sri Lanka Land Development Co-operation (SLLDC). The FMMs implemented by SLLDC were selected from Colombo, Sri Lanka. The quantified damage estimates revealed a reduction in flood damages ranging from 39 % to 63 %, alongside a decrease in flood inundation depths between 9 % and 12 %, and the results underscore the significant effectiveness of FMMs in managing urban flooding and minimising its impacts.

This construction method offers many advantages, such as rapid assembly, an excellent strength-to-weight ratio, and appealing aesthetic features. In a platform-type construction, each story is constructed by placing the floor panels on top of the load-bearing wall, creating a platform for the level above. Although this method offers numerous advantages, recent research findings have revealed that cross-laminated (CLT) platform buildings with conventional connections, such as wall-to-floor hold-down brackets and shear connectors with nails and screws, are prone to experience a high degree of damage under design-level earthquakes. Consequently, conventional connections in platform-type construction are vulnerable to more damage under aftershocks and do not meet the damage avoidance requirements of seismic design. This paper introduces an innovative floor-to-wall connection for a platform-type low-rise mass timber building that mitigates the limitations of conventional connections. The effectiveness of the proposed connection has been investigated, and the seismic performance of the system, which incorporates the proposed connection, has been outlined in this paper. A numerical model with an innovative inter-story isolation system is developed in ETABS, and the seismic performance of the isolated structure was evaluated using Response Spectrum Analysis (RSA) and Nonlinear Time History Analysis (NLTHA).

This shift enables a comprehensive assessment of structural resilience by examining the bridge's ability to endure various hazards throughout its lifespan. This study provides a comprehensive review of two key research domains that have emerged in the field of bridge life-cycle analysis, namely life-cycle sustainability (LCS) and life-cycle performance (LCP). The discussion on the LCS of bridges encompasses both assessment-based and optimization-based studies, while the exploration of LCP focuses on research examining structures subjected to deterioration over their service life due to deprecating phenomena such as corrosion and relative humidity changes, as well as extreme hazards like earthquakes and floods. Moreover, this study discusses the integration between LCS and LCP, highlighting how combined consideration of these factors can minimize damage costs, improve resiliency, and extend the lifespan of the structure. A detailed evaluation encompasses various life-cycle metrics, structural performance indicators, time-dependent modelling techniques, and analysis methods proposed in the literature.
