An economical reinforced concrete is produced by reducing the diameter of steel bar by using fiber ropes. We have examined the compressive and flexural strength of fiber-reinforced concrete. In this study, concrete mix is prepared by using coir fibers. Although instead of using only conventional steel bars, reinforced concrete behavior was investigated with the combination of polypropylene fiber and jute fiber ropes along with steel bars for a constant water binder ratio. These fiber ropes are wound around steel bar with the help of Zepoxy 300 for proper bonding of fiber ropes and steel bar. The results demonstrate that properties of concrete are enhanced by using fibers. Fiber ropes with steel bar in coir concrete increased the flexural strength and compressive strength by 6 and 7%, respectively. Furthermore, it is observed that the addition of fibers in concrete changes the cracking pattern of reinforced concrete beams.","PeriodicalId":17354,"journal":{"name":"Journal of the Mechanical Behavior of Materials","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42995056","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}

Skirted footings are utilized as an alternative to pile driving in poor strength soils at the top layer, such as gypseous soil, to save project costs and time spent installing piles while maintaining excellent performance. The settling of circular skirted footings resting on gypseous soil subjected to loading, infiltration, and collapsing stages was investigated using numerical calculations in this research study to determine their stability under environmental loadings. Finite element analyses were carried out using the commercially available software GEO-STUDIO. The stage of gypseous soil and variable skirt depth to footing diameter ratios (d/D) were taken into consideration. The findings reveal that both the soil stage and the skirt embedment ratio have a substantial impact on the ultimate bearing capacity and the settlement of weak soil, with the skirt embedment ratio increasing resulting in superior skirted footing performance. Furthermore, the improvement in settlement for the loading stage is the smallest, whereas the value for the collapsing soil stage is the largest.","PeriodicalId":17354,"journal":{"name":"Journal of the Mechanical Behavior of Materials","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44773827","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}

The tensile properties and microhardness of dissimilar rod-to-plate joints were evaluated to assess the joint performance.

The microhardness of the weld interface (WI) was higher up to 515 HV0.5. The grain growth and resulting lower hardness in heat-affected zone (HAZ) are mainly responsible for the failure of the joints in HAZ only.

The process of adding a curing ingredient to the concrete mixture to serve as a water reservoir is known as internal curing. IC is a viable technique for supplying additional water for curing cement-based material with lower water-to-binder concrete. It is distinct from externally applied curing. The water meant for internal water curing is dispersed within the concrete after it hardened and facilitated the hydration process. It was used to minimize self-desiccation and shrinkage in UHPC. Based on the reviewed literature, an exchange between mechanical characteristics and autogenous shrinkage for concrete was observed for internally cured UHPC. Even though IC affects the mechanical characteristics, after 28 days, it was possible to achieve a compressive strength of over 150 MPa. Thermal curing was found to exhibit a remarkable effect on the development of UHPC strength. Experimental findings revealed that using pre-saturated aggregates for IC improves the tensile strength of UHPC. The scanning electron microscope images revealed that the bulk of the voids within the super-absorbent polymer cavities are filled with portlandite.","PeriodicalId":17354,"journal":{"name":"Journal of the Mechanical Behavior of Materials","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45859192","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}

An alternative raw material is needed to replace wood at a more affordable price, namely, bamboo laminated boards. However, bamboo has a weak connection between its segments, with a maximum length between components of less than 40 cm. To reduce these weaknesses, the connection between bamboo segments with laminated boards is carried out as follows: scarf joint, butt joint, finger joint, desk joint, and tongue and groove joint. The study aims to determine the connection’s effect on each connection variation’s strength. Tensile tests and bending tests were carried out on the test specimens. The average results obtained were quite varied for the tensile test, which were in the range of 81.36–118.62 MPa, while the results of buckling test were in the range of 395.28–475.89 MPa. This study revealed that the connection of the specimen with seven layers had a value of 118.62 MPa in the tensile strength test and 475.89 MPa in the buckling strength test, while 3 layers finger joint samples with the lowest buckling tensile strength value had a value of 81.36 MPa tensile strength and 395.28 MPa bending strength.","PeriodicalId":17354,"journal":{"name":"Journal of the Mechanical Behavior of Materials","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47875519","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}

There are many types of shear walls, including steel plate shear walls (SPSWs). In enhancing its function, a thin SPSW is added with a stiffener. However, steel shear walls with stiffeners increase construction costs due to the time-consuming factor and the high cost of welding thin plates. Therefore, the infill shape was modified to increase the energy dissipation capacity of the SPSW. This study conducted simulations by varying the geometry, mesh, load factor, and materials used in SPSW. The specimen was modeled and tested using the ABAQUS application’s finite element analysis. The simulation was done by ignoring welded joints, fish plates, and bolts. The result that was the output of the simulation was hysteresis behavior. In addition, the contours that occurred were also observed in this study. The H1 shape had the best hysteresis force–displacement graphics among the nine other geometric shapes. Ten mesh sizes were tested, starting from 25 mm and increasing by multiples of 10 up to 115 mm. The results showed significant differences, with a 33.3% increase at the 115 mm size, which was considered irrational. The load factor represented the applied load in each substep, and a load factor of 2 means the load was doubled compared to a load factor of 1. Seven materials were tested, and high carbon steel outperformed others as it can handle loads up to 1,000 kN, demonstrating excellent energy dissipation capabilities.

Using by-product materials, such as fly ash (FA), to improve soils is a cost-effective and sustainable procedure. Because treatment with FA may lead to reduce shear strength, a FA-based geopolymer was used with a cohesive organic soil to substitute the reduction in strength. A series of unconfined compressive strength tests (UCS) were conducted on compacted specimens treated with FA and geopolymer. The geopolymer was produced by adding sodium hydroxide to activate the FA. Different levels of FA content, curing period, and temperature were applied to the specimens. The results indicate that for the FA treated specimens, the UCS decreased as the FA increased. For the geopolymer-treated specimens, as FA percentage in the geopolymer increased, the UCS increased and the axial strain at failure decreased. The optimum content of FA, in the geopolymer, was 20%, and the highest UCS was achieved at a curing period of 28 days at a temperature level of 65°C. Based on the obtained results, FA-based geopolymer can effectively be used to improve the strength of organic soils.","PeriodicalId":17354,"journal":{"name":"Journal of the Mechanical Behavior of Materials","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49206021","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}

Nanoparticles (NPs) of alumina (Al2O3) with a size of 25 nm were incorporated into an aluminum piston alloy to examine the effect of the NP addition on wear resistance and fatigue behavior. The stir casting method has been utilized to manufacture experimental samples of the composite material by altering the particle weight ratio of aluminum to the matrix alloy to 2, 4, and 6 wt%. The surface morphology of the samples has been examined using an electronic scanning microscope. The results of the wear and fatigue tests indicate that the addition of Al2O3 to the composite enhanced its fatigue resistance and wear strength, with the exception of 6 wt% weight ratio. The best improvement in wear resistance and fatigue strength occurs at 4 wt% Al2O3 particles, which are 12.13 and 67.5%, respectively, more significant than the pure metal and other composites. The mechanical properties of the alloy samples have been enhanced by adding Al2O3 NPs of 25 nm size into the piston’s aluminum matrix alloy. Stir casting was employed to produce the needed composites by incorporating Al2O3 NPs at varied weight percentage ratios of 0, 2, 4, and 6 wt% into the master alloy.
