Prediction of California Bearing Ratio (CBR) of Stabilized Expansive Soils with Agricultural and Industrial Waste Using Light Gradient Boosting Machine
- 2021
Using agricultural and industrial waste such as bagasse ash, groundnut shell ash and coal ash in stabilizing expansive soils are used as a subgrade material to reduce harmful impaction of swelling/shrinkage of expansive soils, reduce construction costs. It is also a solution for environmental protection. California Bearing Ratio (CBR) is an important criterion to evaluate the application technique......

Estimation of California Bearing Ratio of Soils Using Random Forest based Machine Learning
- 2021
California Bearing Ratio (CBR) is an essential parameter utilized to evaluate the strength of the soil subgrades and base course materials of different types of pavements. In this study, the Machine Learning (ML) approach has been adopted using Random Forest (RF) model to estimate the CBR of the soil based on 10 input parameters such as Plasticity Index (PI), Liquid Limit (LL), Silt Clay content (......

Estimating the Compressive Strength of Self-compacting Concrete with fiber using an Extreme Gradient Boosting model
- 2023
Self-compacting concrete reinforced with fiber (SCCRF) is extensively utilized in the construction and transportation industries due to its numerous advantages, such as ease of building in challenging sites, noise reduction, enhanced tensile strength, bending strength, and decreased structural cracking. Traditional methods for assessing the compressive strength of SCCRF are generally time-consumin......

Nonlinear buckling and postbuckling of spiral stiffened FG-GPLRC cylindrical shells subjected to torsional loads
- 2021
The nonlinear buckling behavior of functionally graded graphene platelet reinforced composite (FG-GPLRC) cylindrical shells reinforced by ring, stringer and/or spiral FG-GPLRC stiffeners under torsional loads is studied by an analytical approach. The governing equations are based on the Donnell shell theory with geometrical nonlinearity of von Kármán-Donnell-type, combining the improvability of Le......

Prediction of compressive strength of concrete at high heating conditions by using artificial neural network-based Bayesian regularization
Tập 2 Số 1 - Trang 9-21 - 2022
Cement concrete is the most commonly used material today for constructing residential or commercial buildings, industrial parks, or particular components such as tunnel slabs where there is a high risk of fire. This structure requires concrete to be subjected to high temperatures generated by fires. However, concrete under the influence of high temperature has very complex behavior states with def......

Temperature effect on the characteristic quantities of microstructure and phase transition of the alloy Ag0.25Au0.75
- 2023
In this research, Molecular Dynamics (MD) simulations were conducted to explore the temperature effect on the microstructure and phase transition of the Ag0.25Au0.75 alloy. The findings reveal that as the temperature rises, the material's phase transition switches from crystalline to liquid and vice versa. Notably, during the phase transition, significant changes occur in the link length (r), the ......
