Simulation of Pulling the Reinforcing Bar from Concrete Block with Account of Friction and Concrete Damage

摘要

A direct finite element modeling of the pulling process of the steel reinforcing bar out from the concrete block with taking into account the cohesive behavior of steel-concrete bond and using elastic-plastic-damage constitutive equations for the concrete is considered. The comparison of obtained results of finite element simulations with experimental data is presented and discussed for the problem of pulling the reinforcing bar from the concrete block.
