The justification for conducting research using Bayesian networks is the fact that its effectiveness has been confirmed in many issues in civil engineering and related disciplines. On this background, implementations of this methodology in the issue of structural reliability are particularly distinguished. Bayesian network inference models can also serve as effective decision support systems in the context of complex design processes and construction project implementation. The research was based on a database of information about the determinants of the risk process associated with the necessity of additional construction work. Using this collected information, the Bayesian network methodology was implemented, particularly the GOBNILP network structure extraction algorithm. Due to the properties of Bayesian networks, the created model can be applied both in forecasting the risk of additional works becoming necessary, as well as in diagnosing the causes of such necessity. An additional advantage of this model is its interpretability, resulting directly from the connections (edges) between individual nodes forming the DAG (Directed Acyclic Graph) structure. The validated Bayesian network, understood as a generative AI tool, can also be used for data augmentation. This, in turn, can lead to a more detailed description of the process and make it possible to analyse the sensitivity of the model with respect to its variables encoded in the form of nodes of the DAG structure. It should be emphasized that in previous attempts to use Bayesian networks in engineering applications, their structure was typically specified by the user (expert) and had an arbitrary character. Therefore, the research presented in this work, concerning the autonomous extraction of Bayesian network structure from data, represents a significant achievement in the field of civil engineering.</p></div>","PeriodicalId":55474,"journal":{"name":"Archives of Civil and Mechanical Engineering","volume":"25 4","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s43452-025-01214-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These aspects are more remarkable at early ages due to the lower strength and stiffness developed by the concrete matrix. The stitching effect of the 66.8% by weight of Glass Fiber-Reinforced Polymer (GFRP) fibers contained in Raw-Crushed Wind-Turbine Blade (RCWTB) can counteract these phenomena. This research analyzes the bending behavior of concrete made with up to 100% CRA in combination with 6% RCWTB as aggregate replacement. Early ages (1, 3, and 7 days) and both moist and ambient curing are considered to cover all possible put-into-service situations of concrete elements. Compared to concrete with the same composition but without RCWTB, this waste increased the pre-failure compliance by up to 26.9%, the failure deflection by up to 12.8%, and the failure stress by up to 37.5% when combined with as much as 50% CRA. An earlier concrete age and ambient curing made such effects more notable due to the weaker cementitious matrix. Furthermore, RCWTB provided post-failure load-bearing capacity to concrete, the incorporation of 6% RCWTB to concrete with 50% CRA increasing the absorbed energy under bending loading by 135%. RCWTB also allowed the energy absorbed by concrete to be almost unaffected when adding any CRA amount. All these effects were statistically significant and demonstrate that RCWTB improves the bending deformability of concrete produced with CRA, mainly because of the deflection improvement it caused.</p></div>","PeriodicalId":55474,"journal":{"name":"Archives of Civil and Mechanical Engineering","volume":"25 4","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s43452-025-01215-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144073852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 scope of the experiment included the performance of high-cycle mechanical tests using reciprocating motion, imitating friction processes that occur during the use of implants. Measurements and identification were also carried out of the type of wear generated by friction (tests of surface topography and changes in chemical composition). Examination of friction surfaces revealed all mechanisms of abrasive wear, i.e., microcutting, scratching, and furrowing. In the case of traditional locking caps, furrowing and scratching were most frequently observed, while for caps coated with diamond-like carbon (DLC), the dominant mechanism was scratching. For most of the friction nodes tested, those with a passive coating showed significantly greater wear than friction nodes with a DLC layer, regardless of the screw implantation angle.

The Advance Rate (AR) is a key performance indicator for TBM, and accurate AR prediction is crucial for optimizing shield tunneling operations. This paper proposes a real-time AR prediction method for double-line subway projects, using data from the Shenzhen–Dayawan Intercity Line at Bainikeng Station. The method employs Wavelet Denoising (WD) for data preprocessing and develops a time series data structure scheme to enhance prediction accuracy. GWO-BiLSTM algorithm combination is first applied to tunneling prediction and benchmarked against seven conventional machine learning and deep learning algorithms. Three evaluation metrics (R², MAE, and RMSE) are used to comprehensively assess the model’s performance. The proposed method achieves an R² of 0.98022, with MAE and RMSE values of 2.1139 and 2.9527, respectively, indicating a significant improvement over other models. The improvements in data processing, time series data structuring, and algorithm integration demonstrate the superiority of the proposed method.

An orthogonal experiment with six factors and five levels was designed to comprehensively explore the influence mechanism and optimal dosage of polypropylene fibers (PPF), expandable polystyrene (EPS) particles, and alkali activators. The results show that: (I) An appropriate amount of PG can effectively promote the reaction and assist in the formation of pores in the foam, which is attributed to the fact that PG can preferentially and rapidly dissolve and participate in the reaction to generate ettringite under strong alkaline environment. (II) An alkali activator with a modulus of 1.1 and a Na₂O content ranging from 10 to 12% optimizes both the mechanical and thermal insulation properties. It enables foam materials with a density of 536 kg/m³ to achieve a compressive strength of 3.68 MPa while maintaining a thermal conductivity of 0.1033 W/(m·K).
