1 ANSYS based analysis of low density rc slab with metal meshing = Phân tích sàn bê tông cốt thép có trọng lượng riêng thấp bằng mô phỏng số ANSYS / Huynh Han Phong // .- 2025 .- No. 03 .- P. 102-106 .- 690
Shear failure of punching pertaining to slab of concrete reinforced type consisting of metal mesh expansion and lower density aggregates was simulated numerically in this study.
2 Cracking moment of rectangular reinforced concrete sections corresponding to the bi-linear stress-strain diagram of concrete = Tính toán mô men kháng nứt của tiết diện dầm bê tông cốt thép ứng với mô hình ứng xử phi tuyến song tuyến tính của bê tông / Nguyen Viet Hung // .- 2025 .- Tháng 1 .- P. 168-172 .- 690
The paper has also calculated the cracking moment of reinforced concrete sections corresponding to different reinforcement ratios, the calculation results have showed that: (1) the cracking moment increases linearly as a function of tensile reinforcement ratio and of compressive reinforcement ratio; (2) the tensile reinforcement ratio has a great influence on the cracking moment while the influence of compressive reinforcement ratio is insignificant; (3) the approximate method presented in TCVN 5574 – 2018 significantly underestimates the cracking moment of the section, especially in the case of high tensile reinforcement ratio.
