To resolve this issue, perforations were made in the beam flanges within the connection panel to improve the concrete filling. To investigate the structural performance of continuous beam-type circular concrete-filled steel tubular beam-to-column connections with perforations in the connection panel, an experimental study was conducted using T-shaped sub-assemblage specimens. The experimental parameters considered were the presence of perforations in the flange within the connection panel and beam-fixing types. All specimens exhibited a beam-yielding failure mechanism, characterized by large hysteresis loops and a high energy absorption capacity. For the specimens with perforations in the beam flange within the connection panel, strain concentrations were observed near the perforations when a tensile force was applied to the beam flange. However, no deterioration in the hysteretic behavior owing to this factor was observed. In addition, a finite element analysis was conducted. The stress transfer mechanism within the connection panel was examined based on the results of the analyses.","PeriodicalId":42793,"journal":{"name":"Japan Architectural Review","volume":"8 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/2475-8876.70058","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145581296","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}

To explore this hypothesis, we selected the Kiyotsu Gorge Tunnel as a case study. This tunnel provides a controlled spatial environment with limited external visual stimuli and includes four viewing decks that open to the outside, allowing natural light, air, and temperature variation to enter the interior. The renovation was intended to couple visual stimuli with airflow variation, under the hypothesis that this co-variation may strengthen psychological responses. Architectural elements, including water ponds and reflective mirrors, were introduced to enhance airflow or reflection from the exterior and intensify sensory engagement. Through this combination of visual and environmental cues, the project sought to create a cohesive, immersive experience throughout the entire tunnel.","PeriodicalId":42793,"journal":{"name":"Japan Architectural Review","volume":"8 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/2475-8876.70055","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145366297","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}

However, this approach may overestimate the actual ultimate flexural strength of circular CFST beam-columns, particularly when the diameter-to-thickness ratio is large and/or high-strength materials are used. To address these limitations, a strength evaluation formula that considers the stress gradient and the extreme compression fiber strain of concrete has been proposed for cases beyond the application range of the AIJ Recommendations. Nevertheless, when high-strength materials are employed, the influence of the scale effect of concrete must also be considered, in addition to the stress gradient, to ensure accurate estimation of ultimate strength. In this study, a simplified evaluation method is proposed for calculating the ultimate flexural strength of circular CFST beam-columns, incorporating the stress gradient, extreme compression fiber strain of concrete, and scale effect of concrete. Additionally, the study investigates the appropriate strain at the extreme compression fiber of concrete necessary for accurate strength prediction. The proposed method can accurately evaluate the ultimate flexural strength, regardless of the steel yield strength or the diameter-to-thickness ratio.","PeriodicalId":42793,"journal":{"name":"Japan Architectural Review","volume":"8 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/2475-8876.70051","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144905516","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}

As libraries diversify their functions, co-location with other public institutions has emerged as a global trend, also evident in Finland. This study posits that spatial design and multifunctional utilization of composite buildings have contributed to increased library visitor numbers. Analysis reveals that some Helsinki libraries have expanded their functions by leveraging lobbies and shared audiovisual equipment within composite buildings. These lobbies are characterized by external visibility, spatial layering that enhances user experience, and diverse access to institutions. In libraries, multifunctional spaces are designed to reflect the functions of composite buildings while considering users' psychological traits: Public libraries co-located with schools create spaces that stimulate children's curiosity, while those in cultural centers create spaces that promote a sense of belonging. The findings suggest that these spatial design elements attract more visitors and cultivate environments conducive to community engagement. Lastly, this study recommends further research into challenges faced by composite libraries to enhance understanding of key considerations in their planning and design. The findings may serve as a valuable reference for spatial strategies in composite libraries worldwide.","PeriodicalId":42793,"journal":{"name":"Japan Architectural Review","volume":"8 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/2475-8876.70043","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144894466","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}

Various methods have been proposed to enhance the impact resistance of RC structural members, such as using high-performance materials or surface strengthening with sheets or strip materials. However, these methods may increase construction costs and procedures, making widespread application challenging. This study proposes an anchoring system for the ends of steel deck plates to suppress debris scatterings. Because steel deck plates are commonly used under RC slabs in building construction as permanent formworks or materials for composite slabs, this system is cost-effective and straightforward. A half-scaled impact test was performed to compare specimens with and without the anchoring system, validating its effectiveness in suppressing debris scatterings. Additionally, a component pull-out test and a finite element analysis were conducted to explore the anchoring system's behavior, followed by an impact analysis considering the pull-out of the anchoring system based on the results of component tests and analyses. The analysis replicated the variation in deck plate detachment behavior with and without the anchoring system.","PeriodicalId":42793,"journal":{"name":"Japan Architectural Review","volume":"8 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/2475-8876.70052","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144894092","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}
