In conclusion, the research showed an urban design solution utilizing the transformation of open spaces in a mass housing neighborhood near Naples (south Italy). The project converts empty and abandoned areas within the neighborhood into a new agro-urban landscape crossed by pedestrian and bicycle paths and surrounded by small rest areas where people can sit and enjoy the landscape and panoramic views.

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}

The results of the regression analysis revealed that, workers above 50 years of age had higher odds of experiencing workplace injuries, respiratory health problems, and physical fatigue than workers below 50 years of age. The odds of experiencing respiratory problems is higher in male construction workers than female construction workers. Also, construction workers involved in commercial and infrastructure project types had higher odds of experiencing injuries in workplace compared to workers involved in residential project types.
