Abstract

This study proposed a numerical model based on 3D RBSM to realistically simulate bond behavior of deformed rebar in concrete. In this model, rebar was modelled by beam element subjected to local bond model through link element and concrete was modelled by rigid particles using a Voronoi mesh with random geometry. The proposed model could automatically simulate the effect of cover thickness on bond stress slip relationship and cracking behavior from rebar. It was confirmed that the model is a suitable alternative of 3D modelling of deformed rebar with rib to simulate bond behavior, while providing a low-cost numerical tool along with less time consumption.
