A particular focus is placed on investigating the correlation between different ground motion parameters, especially the ratio of peak ground acceleration (PGA) to peak ground velocity (PGV), which is a critical parameter for classifying ground motion suites in nonlinear time history analyses of structures. Using Pearson correlation, the study highlights that mean time exhibits the strongest correlation with the PGA/PGV ratio for far-source earthquakes.

The research is based on a unique dataset of 8,541 rows and diverse features, developing a predictive framework that enhances crack detection and forecast capabilities. The approach mainly deals with heterogeneous data using the CatBoost algorithm, given its capability for high-accuracy predictions, while AVOA optimizes feature selection, reduces the computational cost, and guarantees no loss in model performance.

Likewise, Wenner resistivity is a crucial durability parameter to be taken into consideration while monitoring the performance of any concrete members. This paper presents novel prediction models for normal concrete’s compressive strength, static modulus, and Wenner resistivity based on linear regression models and artificial neural networks (ANN). Due to the quicker rate of output convergence, the study used the Levenberg–Marquardt learning algorithm for the ANN model to forecast the aforementioned parameters. The prediction strength (R2) of the ANN technique is 14–20% higher than that of the normal regression model, 11–14% higher than that of the static modulus model, and 10–12.5% higher than that of the Wenner resistivity model. For both ANN and linear regression models, the input parameters considered were the rebound number and pulse velocity. The sample was evaluated by substituting normal stone aggregate (NSA) with varying amounts of recycled concrete aggregate (i.e., 0%, 25%, 50%, 75%, and 100% RCA) as a coarse aggregate. This study considered age (14, 28, and 90 days) and grade (M20, M25, and M30) into consideration while developing the models.

Accordingly, the fine aggregates (FA) and coarse aggregates (CA) with fixed gradation sizes were considered and the prepared conventional concrete samples were assessed for their 7th and 28th day compressive strength. Thereby, three different types of FA were selected for FA particle size gradation. Striking variations in the CS values were noted for the concrete samples with a particular combination of FA and CA sizes, and for a fixed choice of the water-to-cement ratio. Further investigations for the CS modelling are conducted with the response surface methodology (RSM). Considering overall specific gravity (FA Sp.Gr.) as a parameter but not a factor, the experimental design considered the FA size (in µm) and CA size (in mm) as independent variables. The best-fit RSM model analysis inferred the quadratic model with good relevance (<i>p</i> < 0.001) for the prediction CS in the defined factor space and for three alternate FA types. The Pareto plots revealed that while the FA size was the influential factor for both responses for the case of the FA Sp.Gr. value of 2.59, while CA size was the highest contributor for the other two FA Sp.Gr. types. Thereby, the role of the type of FA and the aggregate sizes were assessed to be very important to achieve the high CS.

Among various passive strategies for energy efficiency in buildings, building envelope shading is considered a key strategy to control solar heat gain and reduce the cooling loads in buildings. While significant focus has been given to shading glazing components of buildings, this paper addresses a critical gap by investigating the potential of shading the opaque envelope components (OECs), which include opaque walls and roofs. OECs can reduce cooling load by managing the heat ingress into the buildings. Although OECs are not widely used in energy-efficient building strategies, the passive strategies in OECS help control heat gains and decrease cooling loads, especially in hot climates. This study investigates the shading strategies of opaque OECs in a two-stage review, initially reviewing the global building energy codes to assess the inclusion of OEC shading strategies and then identifying effective shading techniques for walls and roofs through a systematic literature review. The review of energy codes reveals that very few energy codes explicitly address OEC shading with a single instance mentioned in the energy codes of Australia and India. In contrast, all the codes explicitly specify window shading as a passive strategy. The SLR further demonstrates that the shading OECs can significantly reduce cooling demands, with strategies such as overhangs, green facades, double-skin roofs, and photovoltaic panels showing up to 77% energy savings. The shading potential provides considerable scope for integrating the shading of OECs as a passive strategy that can be incorporated into the energy for better adoption in the buildings.</p></div>","PeriodicalId":8513,"journal":{"name":"Asian Journal of Civil Engineering","volume":"26 5","pages":"1865 - 1879"},"PeriodicalIF":0.0,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143888739","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}
