The image-based model outperformed previous approaches using both image and non-image inputs. The components contributing to pleasantness–unpleasantness were identified through Shapley-Additive-exPlanation analysis. Results showed that green space, traffic elements, pedestrian amenities, and street materials impact visual quality with varying combination effects. This study advances urban evaluation by developing an automatic method to predict streetscape quality and analyze microscale components.

Despite impact damage, RC beams retained residual flexural strength similar to undamaged beams but exhibited reduced flexural stiffness and ultimate deflection. However, UHPC and URSHCC experienced decreased load capacity after impact due to deformation beyond their tensile strain limits.

At present, there are no standardized methods for determining monitoring thresholds for high-formwork support systems, and existing monitoring systems lack trend prediction capabilities, limiting their effectiveness in advance prediction and early warning of structural responses. This paper aims to propose a data-model hybrid-driven framework for determining and updating monitoring thresholds, as well as for short-term response prediction of high-formwork support systems. The proposed framework consists of three key modules. The first module is a visual monitoring system for detecting structural displacement, which collects data, issues real-time warnings, and continuously feeds information to the second module. The second module focuses on determining and updating monitoring thresholds through a data-model hybrid approach and supplies extensive training samples for the third module. The third module concentrates on short-term prediction of structural displacement response and construction load inversion using the CNN-BiLSTM-Adaboost algorithm. This algorithm predicts displacement trends in high-formwork support structures up to 1 h in advance, providing early warnings. Additionally, it quickly and accurately estimates the upper construction load, enabling precise emergency measures and reducing the impact of adverse load effects.</div></div>","PeriodicalId":34137,"journal":{"name":"Developments in the Built Environment","volume":"22 ","pages":"Article 100645"},"PeriodicalIF":6.2,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143697759","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}

Results indicate that nanobubbles reduce internal friction within the cement slurry by acting as lubricants between cement particles, improving flowability by 7.5 % and enhancing rheological properties. Their surface electronegativity facilitates uniform particle dispersion, thereby increasing slurry stability. Furthermore, XRD and SEM analyses reveal that nanobubbles accelerate hydration kinetics by providing abundant nucleation sites, promoting calcium hydroxide (CH) formation, and refining the microstructure.

The cradle-to-gate LCA includes raw material extraction, transportation, production, and carbonation during mixing and curing.
