stimating punching shear capacity (PSC) of steel fibre reinforced concrete slabs (SFRCS) is a crucial task in structural design. This study investigates the performances of artificial neural networks trained by the adaptive moment estimation (Adam) method in dealing with the task of interest. To alleviate overfitting problem, decoupled weight decay (AdamW) and L2 regularization (AdamL2) are used.
2 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.

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.
