A DDPM with a U-Net architecture is employed to generate high-fidelity microstructure images that closely resemble those derived from SEM. The synthesized images are subjected to comprehensive image analysis, phase segmentation, and micromechanical analysis to validate their accuracy. Findings demonstrate that DDPM-generated microstructures not only visually match the original microstructures but also exhibit similar greyscale statistics, phase assemblage, phase connectivity, and micromechanical properties. This approach offers a cost-effective and efficient alternative for generating microstructure data, facilitating advanced multiscale computational studies of cement paste properties.</div></div>","PeriodicalId":34137,"journal":{"name":"Developments in the Built Environment","volume":"21 ","pages":"Article 100624"},"PeriodicalIF":6.2,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143427847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research began with a detailed evaluation of the setting times of AAS mixtures, optimizing activator compositions to identify formulations suitable for concrete productions. Employing the Bingham and Herschel-Bulkley models, it was observed that AAS concrete with a lower silicate modulus (Ms) predominantly exhibited shear-thinning behavior. As the Ms increased, a shift toward shear-thickening behavior occurred, becoming more pronounced with higher concentrations of alkaline compounds in the activators. Furthermore, the fresh properties of AAS concrete significantly improved with increased alkali dosages in the activators, resulting in reduced dynamic yield stress and plastic viscosity, along with enhanced workability retention over time.</div></div>","PeriodicalId":34137,"journal":{"name":"Developments in the Built Environment","volume":"21 ","pages":"Article 100623"},"PeriodicalIF":6.2,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143422580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, condition data is affected by survivorship bias. This work addresses this issue by developing a composite analysis based on explainable artificial intelligence techniques to analyze condition data and derive degradation models for existing bridge components. The analysis comprises four steps: (1) cluster analysis of damage transition times using the k-means algorithm to identify damage patterns with similar damage evolution rates (fast, normal, slow, corresponding to bridge components with a fragile, normal, and robust deterioration behavior); (2) Random Forest classification to predict the cluster based on bridge inventory data; (3) SHAP analysis to explain the predictions of the Random Forest classifier; (4) application of the gamma process to the grouped damage transition times to assess damage evolution. SHAP analysis reveals survivorship bias, indicating that fast-evolving damages primarily affect newly built bridges, while slow-evolving damages are associated with older bridges. By clarifying the composition of the clusters and the population of bridges to which the damage belongs, SHAP analysis also enables the development of bias-aware degradation models. The approach is demonstrated through the analysis of crack evolution in reinforced concrete bridges in Germany.</div></div>","PeriodicalId":34137,"journal":{"name":"Developments in the Built Environment","volume":"21 ","pages":"Article 100617"},"PeriodicalIF":6.2,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143394421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total number of 56 policies, issued by the central government from 2001 to 2023 in China, were selected as data for content analysis. Using the Dynamic Topic Modeling, six main topics were identified from the texts: informatization development, smart construction, construction industrialization, BIM technology application, prefabricated building, and digital workforce. The results indicate that environment instruments have become central tools for the government to promote digital transformation. Stakeholders involved in digital public policies have remained relatively stable, with the government as the primary actor.

In this article, the damage cases formed under the effect of the impact load acting on the weak axis of I-section steel beams under repeated impact loads are investigated and the effect of the geometric shape of the falling weight on the element behavior is evaluated by experimental and numerical methods. A 2000 mm long IPE160 section simply supported beam is subjected to impact load in the weak axis direction. The 100 kg impact load is applied from a height of 2200 mm with a hammer head having three different geometric shapes (rectangular, circular and triangular). Three-dimensional finite element models of the 6 experimental studies were analyzed using Abaqus Explicit software. In order to determine the effect of the geometric shape of the falling weight on the beam behavior under the effect of repeated load; five parameters such as displacement, acceleration, support reaction, stress distribution and plastic strain were investigated. The displacement, acceleration and support reaction formed in the beams were numerically investigated by means of finite element models and compared with the experimental results. The results obtained showed that the maximum deflection and acceleration occurred in the beams hit by the triangle-headed impact crusher. In addition, the largest plastic deformation and stress distribution were observed in the tests performed using triangle-headed impact crushers. In the series I (rectangular), II (circular), III (triangular) test series, the displacement value increased by 44%, 79% and 100%, respectively, compared to the first impact. It is seen that the 2nd degree effects play an important role in the increase of the damage level in the second impacts. It was determined that the maximum reaction force tended to increase from Series I to Series III. This shows that reducing the contact area of the falling weight significantly increases the reaction forces.</div></div>","PeriodicalId":34137,"journal":{"name":"Developments in the Built Environment","volume":"21 ","pages":"Article 100620"},"PeriodicalIF":6.2,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143096936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the promising benefits of BIM in terms of successful project deliveries and enhanced building performance, construction firms struggle to view assets from the perspective of a whole asset life cycle context, and consequently struggle to derive their full potentials via BIM, especially in the operations and maintenance (O&amp;M) phase. One of the fundamental reasons behind this challenge is the lack of empirical understanding of what information should be collected to support efficient and effective operation and maintenance management. Various BIM capability maturity models have been proposed to support BIM integrations into O&amp;M management, but most of these models fail to capture detailed information requirements (IRs). Furthermore, there is limited insights regarding the prioritisations of these IRs to guide construction firms and asset owners towards operational competitiveness and excellence. To address these gaps, this study aims to develop a BIM and O&amp;M maturity assessment model (BIM and O&amp;M MM) by drawing on the capability maturity model integration (CMMI) concept, and utilising Delphi technique and maturity grids. The developed tool enables asset owners and managers to assess BIM and O&amp;M integration maturity of built assets, based on a five-level maturity scheme across 21 IRs. To ensure effectiveness and practicality of the tool, 22 experts assessed the tool, and the results indicate its ability to succinctly measure the maturity level of BIM and O&amp;M integration, thereby enabling construction managers and asset owners to identify areas of strengths and deficiencies for prioritising capital investments. The BIM and O&amp;M MM ensures stakeholder alignment and addresses real-world O&amp;M challenges. It enhances data consistency, optimised long-term asset management, data-driven decision-making, and provides a foundation for future research and technology integration.</div></div>","PeriodicalId":34137,"journal":{"name":"Developments in the Built Environment","volume":"21 ","pages":"Article 100619"},"PeriodicalIF":6.2,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143300055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
