Integrative numerical and analytical approaches to bond strength in lightweight concrete: Innovative modeling and parametric insights for ribbed steel bars and seven-wire strands
This study explores the bond behavior between steel reinforcement and lightweight concrete (LWC), focusing on ribbed steel bars and seven-wire strands.Utilizing finite element (FE) analysis with ATENA 3D and ATENA-GiD software, along with analytical methods, the research examines the impact of bar diameter and concrete compressive strength on bond
