Deterministic behavior of an anchoring plate and sensitivity study

The prediction of the resistance of concrete anchors is essential for ensuring the safety of sensitive infrastructures.This study proposes the use of an energetically regularized damage model in tension and compression (RTC), based on an extended version of Mazars' model.In addition to regularization, modifications have been made to better capture material behavior, particularly in compression, to simulate the pull-out tests of anchors.Finite element simulations using the Cast3M software are employed to analyze concrete cracking, considering both the behaviors of concrete and steel.The simulation results reveal two main failure modes: the formation of a concrete breakout cone or steel fracture.The first part of the study compares the results of experiments from the literature with simulations based on embedment length.The second part focuses on a sensitivity study of various parameters, including embedment length and plate stiffness.It appears that embedment length is a highly influential factor in the resistance of concrete anchors, and that anchor geometry can also have a significant impact.
