Many EU countries have decided to add new embodied carbon regulations in their building codes, and thus, the calculation of environmental impact is becoming mandatory. We present a decision support system based on Building Information Modelling (BIM) that provides architects and engineers with streamlined LCA information on highly uncertain designs at an early stage. The system is designed to be extremely simple and easy to comprehend, and it executes LCA calculations fast enough for real-time use. Our key contribution is to elaborate, comprehensively implement, and evaluate the new <i>sustainability opportunity metric (SOM)</i> that we had briefly introduced in our earlier work. Assigned to BIM model components, the metric intends to identify sustainability opportunities and risks by quickly evaluating numerous independent building elements despite early-stage design uncertainty. In this paper, we demonstrate the first fully integrated toolchain and tools prototypes as a plug-in for Revit. We develop the tool to conduct visualisation and usability experiments, and empirically evaluate it on five complex BIM-based high-rise projects.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142859790","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}

As a common preventive strategy, the use of a standard checklist has become a traditional technique widely adopted today. However, this procedure might not capture the full spectrum of risk levels or address interconnected issues, thus potentially compromising effective risk management. Conversely, allowing for prioritization and immediate remediation of fire hazards, the incorporation of expert knowledge and data-driven insights to gauge risk factors is noteworthy. In this context, the approach proposed, rooted in fuzzy Petri nets, optimizes resource allocation by focusing on the highest-risk elements, leading to a more substantial risk reduction. An enhanced methodology was implemented, considering the pre-fire conditions at the Brazilian National Museum. Simulation results indicate that simple corrections in the electrical installation could have significantly reduced the fire risk, possibly preventing the tragedy. These findings underscore the method's effectiveness, emphasizing the importance of thorough electrical risk management. It suggests that the catastrophe might have been avoided had the risks been appropriately addressed. The model emerges as an essential instrument for enhancing risk assessment and strategic resource allocation, especially vital in resource-constrained environments characteristic of developing countries like Brazil. However, it is important to clarify that the proposed methodology is based on expert systems, offering an alternative approach to risk quantification when statistical data and deterministic methods are unavailable. This methodology integrates expert judgment and fuzzy logic for qualitative risk assessments, enabling the identification and prioritization of risk factors despite the lack of quantitative data. While sensitivity analysis is not applicable in this context, validation can be achieved through consensus among expert groups who evaluate the model's assumptions and outcomes.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142811056","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}

As climate-induced extreme events become more frequent, developing resilient facades is becoming crucial. Although facades can contribute significantly to the total post-disruption losses, their resilience is not sufficiently addressed in current design approaches. In response to this research gap, this study proposes a multi-criteria decision-making methodology to select optimal facade designs using resilience criteria: resilience loss and economic loss. The framework addresses the complexity of facade design, considering multiple hazards such as earthquakes and heatwaves. For seismic hazard, the facade’s resilience is defined as its ability to mitigate damage. In the case of heat hazard, resilience is assessed based on the ability to keep indoor conditions within a comfortable thermal range. To demonstrate the applicability of the proposed methodology, a case study of an 18-story office building in Izmir (Turkey) is used to compare alternative facade packages. These packages identify the facade design cases, each coupled with a dataset of seismic and thermal fragility curves. Numerical simulations are conducted to derive seismic and thermal resilience curves for each facade package, along with resilience criteria. These criteria are embedded into a practical decision-making process to enable the selection of the optimal design case based on project specifications.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"4 2-4","pages":"195 - 210"},"PeriodicalIF":0.0,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44150-024-00116-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142415118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the need for sustainable infrastructure has progressed with the increasing use of various plant-based natural fibers for structural applications. This study assesses the feasibility and performance of using natural fiber rope-based reinforcement in foamed concrete structures. The flexural behavior of foamed concrete beams reinforced with the roselle fiber rope-based reinforcement is investigated using finite element (FE) analysis-based numerical and code-based simplified analytical approaches. In the FE model, beams are discretized along the length and depth with a multi-fiber model approach. The nonlinear constitutive behavior of the concrete is taken as per the design standards, and the material properties of natural fiber-based reinforcement, i.e., roselle fiber and roselle fiber rope, are obtained experimentally. The bond-slip behavior between reinforcement and concrete is also implemented using Eligehausen’s law. Furthermore, the influence of the elastic modulus of the reinforcement, span length, and reinforcement ratio on the flexural capacity and deflection of the beams is investigated. The study provides an understanding of roselle fibers and roselle fiber rope in terms of tensile strengths and stiffness to explore their suitability as reinforcement materials. Moreover, it is shown that roselle fiber rope-based reinforcement increases the load-carrying capacity of reinforced foamed concrete beams by approximately 90% (depending upon the elastic modulus of the reinforcement) compared to plain foamed concrete beams. This significant improvement underscores the potential of roselle fiber ropes as an alternative to steel or synthetic fiber-based reinforcement in concrete beams subjected to relatively low-magnitude loads, providing a clear conclusion and recommendation based on the findings of the study.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"4 2-4","pages":"157 - 172"},"PeriodicalIF":0.0,"publicationDate":"2024-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142414099","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}

This liturgical reform aimed to deepen the engagement of worshippers in the liturgy, fostering a more direct connection between the congregation and the celebrant. Architects responded by radically reimagining the design and aesthetics of sacred spaces and embracing innovative materials and construction techniques such as reinforced concrete. This shift enabled the creation of bold, symbolic structures characterized by simple geometric forms, fluid spaces, and enhanced transparency, utilizing natural light to evoke sacred atmospheres. An outstanding example of this architectural paradigm is the Church of the Holy Family in Salerno, Italy, designed by Paolo Portoghesi and Vittorio Gigliotti, starting in 1968. Built entirely in reinforced concrete, this church embodies the fusion of technical innovation with spiritual exploration, typifying ecclesiastical postmodernism. Despite their architectural significance, many postconciliar churches face challenges today, including insufficient conservation efforts and inadequate community recognition. This research focuses on the Church of the Holy Family in Salerno, investigating its evolution, technological advancements, and conservation needs. A comprehensive Conservation Plan is proposed to safeguard this architectural heritage, integrating analyses of degradation and restoration interventions. By addressing these aspects, this study aims to ensure the preservation of this postconciliar religious architecture within contemporary urban and social contexts.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"4 2-4","pages":"173 - 193"},"PeriodicalIF":0.0,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44150-024-00115-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142414045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
