Prediction of shear strength of corrosion reinforced concrete beams using Artificial Neural Network - 2022
Panagiotis G. Asteris, Thuy-Anh Nguyen
The shear strength of corroded reinforced concrete (CRC) beams is a critical consideration during the design stages of RC structures. In this study, we propose a machine learning technique for estimating the shear strength of CRC beams across a range of service periods. To do this, we gathered 158 CRC beam shear tests and used Artificial Neural Network (ANN) to create a forecast model for the con...... hiện toàn bộ
Estimation of California Bearing Ratio of Soils Using Random Forest based Machine Learning - 2021
Dung Quang Vu, Duc Dam Nguyen, Quynh-Anh Thi Bui, Duong Kien Trong, Indra Prakash, Binh Thai Pham
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 (...... hiện toàn bộ

Nonlinear buckling and postbuckling of spiral stiffened FG-GPLRC cylindrical shells subjected to torsional loads - 2021
Kha Hoa Le, Tho Hung Vu, Hong Quan Pham, Hoai Nam Vu
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...... hiện toàn bộ

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
Marijana Hadzima-Nyarko, Son Hoang Trinh
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...... hiện toàn bộ

Temperature effect on the characteristic quantities of microstructure and phase transition of the alloy Ag0.25Au0.75 Tập 3 Số 1 - Trang 45-53 - 2023
Ștefan Țălu , Tuan Quoc Tran, Hoang Van Ong, Ha Thi Vu, Duyen Thi Tran, Thu-Cuc Thi Nguyen
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 ...... hiện toàn bộ
