However, still some aspects of this application need more investigation. This study aimed to investigate the aging effect on some properties of asphalt mixture made by SSA and its comparison with conventional limestone aggregates (LA). Asphalt concrete mixtures with the same binder were made with SSA and LA, and were subjected to different aging conditions. Aging conditions included short-term on loose mixture, and long-term in 2 conditioning times of 5 and 7 days on compacted specimens. Then, the specimens were evaluated by Marshall test, indirect tensile strength (ITS) test, Cantabro abrasion loss test and semicircular bending (SCB) test to evaluate their resistance against rutting, moisture damage, raveling and fracture, respectively. Results reveal that the mixture made by SSA has more Marshall stability, Marshall quotient and ITS, and is more resistant against moisture damage and raveling and has higher fracture toughness and fracture energy than the mixture made by LA. Results also show that aging results in increase of Marshall stability, Marshall quotient and ITS and decrease of flow, moisture damage resistance, raveling resistance, fracture energy and fracture toughness. The effect of aging on the properties was found to vary with the type of aggregates. In general, the mixture containing SSA is less affected by aging than the mixture made by LA. However, for some properties the aging is more effective on the mixture containing SSA.","PeriodicalId":14550,"journal":{"name":"Iranian Journal of Science and Technology, Transactions of Civil Engineering","volume":"121 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141740068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The meta-heuristic algorithms used for calibration in the study were run thirty times each. Thus the reliability, the reliability of the algorithms was tested with the standard deviations obtained. The study also measured the temporal performance of the algorithms. In addition, the baseflows of Göksu station were determined and their percentage rates were found separately according to all three methods and intuitive methods, and the results obtained were compared. By examining the results obtained in this section, the average baseflow rate of the basin was also determined.

By incorporating recycled coarse aggregate (RCA) derived from construction and demolition waste into concrete, waste reduction and natural resource conservation is achieved. An innovative standard compaction method is utilized to investigate the complex dynamics of RCA's influence on concrete properties. Key parameters examined include workability, compressive strength, flexural strength, split tensile strength, microstructural characteristics (XRD, SEM, EDAX), and modulus of elasticity. A distinctive feature of this research involves systematically replacing conventional coarse aggregates with RCA at varying proportions: 0, 25, 50, 75, and 100%. The comprehensive analysis reveals significant improvements in the fresh, hardened, and microstructural properties of concrete. Results indicate a nuanced relationship between RCA replacement levels and concrete strength, with the optimal mixture at 25% RCA replacement (RCA 25) demonstrating notably higher compressive (11.56%), flexural (3.06%), and split tensile (5.17%) strengths compared to the control concrete. Additionally, RCA 25 exhibits an 8.91% increase in modulus of elasticity. XRD, SEM, and EDAX analyses provide insights into the underlying mechanisms, indicating that pozzolanic activity enhances strength at lower RCA replacement levels by producing more hydration products, while strength may decrease at higher replacement levels. The significance of this research lies in its novel methodology, addressing a critical gap in understanding the intricate relationships between RCA content and concrete performance. The findings strongly advocate for the judicious use of recycled materials in concrete, contributing to environmental conservation and the long-term resilience of construction materials.","PeriodicalId":14550,"journal":{"name":"Iranian Journal of Science and Technology, Transactions of Civil Engineering","volume":"61 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141740066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings showed that both gray and tap water can be considered as mixing water, but based on water quality indicators for industry usage, gray water cannot be used without restrictions to build reinforced concrete structures due to its high corrosive ability. Gray water had no significant effect on the slump and setting time of the concrete. The compressive strength of concrete made with tap water increases from 7 days to 28 days, while gray water concrete, after an increasing trend from 7 days to 14 days, reached its lowest value at 28 days (28.1 MPa). This decrease is due to high TDS values and impurities, which can lead to a decrease in compressive strength. Gray water concrete showed a significant loss in tensile strength compared to tap water concrete after 28 days of curing. The P-wave velocity of the tap water concrete sample increased with the increase in curing time, while the gray water sample decreased by 13% in 28 days. Microscopic studies revealed the formation of carbonate halos around carbonate aggregates due to alkaline reactions in both tap and gray water concretes. The carbonate halo has developed to the inner parts of the aggregates in the gray water sample, indicating greater intensity of alkaline reactions. This means the long-term strength of the concrete will likely suffer a significant loss.","PeriodicalId":14550,"journal":{"name":"Iranian Journal of Science and Technology, Transactions of Civil Engineering","volume":"27 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141611573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These models had different steel plate thicknesses, opening aspect ratios, and stiffener configurations. Numerical results of this study agreed with the Plate-Frame Interaction (PFI) theory. It was found that adding stiffeners considerably increased shear stiffness and shear strength of SPSW. Furthermore, improvement in the shear load carrying capacity of the SPSW is significantly influenced by cross-sectional shape and even arrangement of the stiffeners. Finally, it was shown that SPSWs with a thicker steel plate are more sensitive to both the presence of the opening and its widening.","PeriodicalId":14550,"journal":{"name":"Iranian Journal of Science and Technology, Transactions of Civil Engineering","volume":"20 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141585266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, no research has been reported on local scour around inclined bridge piers for clay-sand mixed cohesive beds. This research work was carried out to investigate the impact of dual inclined bridge piers (convergent-vertical piers) on maximum scour depth installed in flow direction on four beds containing different clay contents from 20–80% with sand. Three different pier shapes of different cross sections were tested (circular, rectangular & diamond) in each case. The effect of inclination (0°, 5°, 10°, 15°, 20°) with the vertical on the same beds was analyzed and discussed. The results revealed a considerable reduction in maximum scour depth with inclined bridge piers in comparison with vertical bridge piers. The least scour depth was observed around 10° inclination for rectangular and circular shaped sections and 5° for diamond bridge pier. On average 53.25%, 57.25%, and 72% reduction in scour depth was observed for inclined rectangular, diamond, and circular bridge piers respectively as compared to the vertical bridge piers. The circular bridge pier proved the most effective inclined pier, exhibiting the least scour depth among the three pier shapes. Furthermore, no equation was found in the literature to predict the maximum scour depth around inclined bridge piers on clay-sand mixed beds, so three non-linear regression-based equations for three different upstream collinear piers as a function of clay content percentage and inclination were predicted which reasonably described the experimental data.","PeriodicalId":14550,"journal":{"name":"Iranian Journal of Science and Technology, Transactions of Civil Engineering","volume":"31 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141575028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Design guidelines have been established in ACI 440.11–22 for GFRP bars. However, there's currently no specific code for Basalt fiber-reinforced polymer (BFRP) bars in concrete columns due to limited experimental data. This study investigates using BFRP bars and ties as an alternative to steel reinforcement in concrete columns. It presents results from testing 11 columns under concentric loads. The test variables included the longitudinal BFRP reinforcement ratio, BFRP tie spacings, BFRP tie diameter, and reinforcement type. The experimental results showed a resemblance in the performance of concrete columns reinforced with BFRP and steel bars. Longitudinal BFRP bars contributed between 6.4 and 17.2% to the ultimate load-carrying capacity. A reduction in tie spacing was observed to slightly improve the load-carrying capacity. Moreover, when using the same volumetric reinforcement ratio, employing smaller diameter bars with closer spacings proved to be more efficient than using larger diameter bars with greater spacings. The study also introduced two models for predicting the maximum load capacity of BFRP-reinforced concrete columns, and the proposed models showed high accuracy compared to existing models in the literature.","PeriodicalId":14550,"journal":{"name":"Iranian Journal of Science and Technology, Transactions of Civil Engineering","volume":"55 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141575027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
