Digital Twin and Internet of Things (DT-IoT) systems are widely promoted as tools for enhancing construction cost estimation performance (CEP); however, empirical evidence regarding the major barriers to implementing them and their impact on CEP is limited. This study addressed that gap by developing a survey and administering it to 135 construction professionals to tap into their experience with the barriers to implementing DT-IoT and how, when successfully employed, the systems impact the CEP. The responses were analyzed, and the reliability of the barrier construct was deemed acceptable (Cronbach’s alpha = 0.835). The mean score ranking, Spearman correlation, and Ordinal Logistic Regression (OLR) were used to evaluate the intensity of each barrier, co-occurrence patterns, and associations with CEP levels, and the results showed that resistance to change and technical limitations were the biggest barriers. A correlation analysis indicated strong co-occurrence among barriers, particularly between lack of team spirit and resistance to change, and between lack of a clear roadmap and inadequate interdepartmental communication. The OLR model showed strong explanatory performance (Nagelkerke R² = 0.599) and identified significant effects related to planning, communication, funding, cooperation, and stakeholder alignment, with significant interaction effects indicating compounded barrier conditions. These findings provide empirical evidence on perceived associations between DT-IoT implementation barriers and CEP and offer project managers and professionals an evidence-informed basis for prioritizing implementation strategies that may support more reliable and accurate construction cost estimation practices.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"6 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44150-026-00211-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148782048","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, the rapid increase in demand for good river sand, along with strict regulations on riverbed mining, has significantly limited its availability. Excessive extraction has also led to severe environmental degradation, including ecosystem imbalance and depletion of natural resources. In addition to this, cement, which acts as the primary binder in the formation of mortar, is highly energy-intensive to produce and is a major contributor to global CO₂ emissions, thereby raising serious sustainability concerns. To address these challenges, extensive research was done on alternative materials for replacing natural sand, but most studies are primarily centered on ordinary Portland cement-based mortar systems, with limited attention to Portland pozzolana cement-based applications. The present study made a novel attempt to focus on the development of a sustainable and non-conventional mortar by utilizing crusher dust (CD), a waste material generated during aggregate crushing, as a complete replacement for river sand. Simultaneously, ground granulated blast furnace slag (GGBS), an industrial by-product known for its lower carbon footprint and improved durability properties, was used as a partial replacement for Portland pozzolana cement. Mortar mixes were prepared with varying GGBS replacement levels of 10%, 15%, 20%, 25%, 30%, and 50%, and were evaluated for their mechanical characteristics. The experimental results indicate that mortar incorporating CD and GGBS along with superplasticizer exhibits enhanced compressive strength (47%) at a replacement level 25% of GGBS and reduced water absorption (9%) compared to conventional mortar. Furthermore, the practical applicability of the developed mortar was assessed in masonry using locally available clay and fly ash bricks. The findings demonstrate that the non-conventional mortar performs better than conventional mortar, particularly with clay brick masonry, showing improved strength, bonding, and compatibility. However, with fly ash brick also its performance was well noticeable. Overall, the combined use of crusher dust and GGBS offers a sustainable, eco-friendly, and high-performance alternative for traditional mortar systems.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"6 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148750506","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 paper explores the fresh, mechanical and durable behavior of M40 and M60 grade High volume Flyash Concrete (HVFAC) in the presence of Dolomite Powder (DP) as partial substitutes of Ordinary Portland Cement (OPC). The constant supplementary material was FA, with DP being varied with the replacement levels in order to determine its effect on strength characteristics. An elaborate experimental study was conducted in order to determine the compressive strength and split tensile strength at various curing ages. The results show that the addition of FA and DP has a great influence on the development of the strength in concrete. It was noted that the best proportion of the DP was to be used in increasing compressive and tensile strengths because of its fineness. But increased levels of replacement caused a slight decrease in strength. The behavior of M60 grade concrete was more sensitive to dolomite variation than M40 grade. As a whole, the paper proves that FA and DP can be used together to create sustainable HVFAC with good mechanical performance and at a lower consumption of cement. The results offer precious information on how to optimize the percentage of DP to achieve eco-friendly and long-lasting concrete mix that can be used in the modern construction industry.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"6 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148614078","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 approach includes an analysis of 28 dual-award-winning designs to understand the interplay of structural functionality and aesthetic innovation. It also encompasses a literature review on the historical development of Japan’s architectural education, highlighting the integration of structural engineering subjects as one of the core components of the curriculum. This discussion is not intended to establish a direct causal relationship between the education of individual designers and the quality of the selected buildings. Instead, it provides a contextual framework for understanding the relatively close relationship between architectural and structural thinking in Japan. Findings indicate that structural elements contribute to architectural design in recurring ways, not only through visible material and formal expression but also through less visible roles that enable spatial organization, environmental performance, and functional flexibility. In some cases, structural systems are directly expressed through timber roofs, steel frames, large cantilevers, or concrete slabs. In other cases, structural elements remain visually discreet but support particular architectural intentions. The study therefore distinguishes between visible structural expression and hidden structural contribution. These findings suggest that, in the selected Japanese projects, structural design often operates as both a technical and architectural device. The findings are primarily situated within the Japanese context, but may offer points of reference for broader discussions on collaboration between architects and structural engineers.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"6 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44150-026-00208-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148465501","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}

In highly insulated office buildings, cooling may be required even when outdoor temperatures are low, often dominating the overall energy balance. Night cooling offers an effective and energy-efficient strategy to maintain indoor air quality and thermal comfort by using cool nighttime air to dissipate stored heat. This paper presents the concept, design, and operation of an autonomous night-cooling system that integrates shape memory alloys as an alternate to active mechanical cooling systems.

Unlike conventional pavement models that neglect joint mechanics or subgrade shear interaction, the proposed formulation explicitly incorporates dowel and tie bar stiffness and represents soil–structure interaction using a two-parameter foundation model. The pavement slab is modelled using Mindlin–Reissner plate theory with four-noded quadrilateral elements possessing six degrees of freedom per node, and the formulation is implemented in MATLAB to retain full transparency and flexibility in modelling and numerical control. Realistic multi-wheel surface pressures corresponding to the Airbus A380-800 landing gear configuration are applied to simulate critical operational loading conditions. Model accuracy is verified through mesh convergence analysis and comparison with established analytical solutions, yielding errors below 2%. The numerical results reveal that the combined effects of joint stiffness and Pasternak shear coupling produce a nonlinear redistribution of internal forces across slab interfaces, significantly modifying bending–shear–torsion interaction compared to Winkler-based or joint-free formulations. In particular, the shear layer suppresses bending-dominated response while amplifying localized torsional and shear demands near joints under eccentric aircraft loading, with torsional response increasing by more than 120% relative to symmetric loading. These findings provide new mechanistic insight into jointed pavement behaviour under complex aircraft loads and demonstrate the necessity of advanced soil–joint modelling for performance-based design, assessment, and long-term resilience of airport pavements within the built environment.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"6 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148281658","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 thermomechanical approach considered the interaction between the thermal and mechanical fields. Steel, being ductile and isotropic, had its failure represented by the von Mises theory. Wood, on the other hand, being anisotropic, was modeled orthotropically, exhibiting different behavior in traction and compression, perpendicular or parallel to the fibers. The results of the thermal analysis indicated a carbonization rate of 0.39 mm/min in the timber beams, which resulted in a reduction in the resistant cross-section and a nearly uniform temperature distribution in the cross-section of the steel beams during the course of the fire. With regard to the thermomechanical analysis, it was found that for steel, it is more advantageous to adopt support configurations that allow for axial displacement (AC1) to improve structural resilience by accommodating thermal expansion and preventing collapses. However, the support configurations had no significant influence on the performance of the timber beams, but it is crucial to incorporate measures that reduce the rate of carbonization.
