Bond Behavior of Auxetic Bars in Reinforced Concrete – A Numerical Study

Jesús Antonio García Sánchez,
Carolina Quintero Ramírez,
Paulo Cesar Gonçalves
et al.

Abstract: The study aims to enhance the bonding strength in reinforced concrete using a novel Auxetic Tubular Deformed Rebar (ATDR). A high-resolution non-linear finite element model was developed to perform numerical analysis of pull-out tests (PoT). Two sets of numerical simulations were conducted: one to replicate the concrete behavior under compression and tension tests, and the other for PoT, validated with experimental and numerical data. Numerical tests utilized a microplane model with plasticity-damage, regulari… Show more
