Finite element modelling of monotonic pull-out test of deformed steel rebar embedded in well-confined concrete

A finite element study carried out using LS DYNA and aimed to simulate the monotonic pull-out test of deformed steel rebar embedded in concrete is presented this paper. Three models interface between well-confined concrete, i.e. perfect bond model two bond-slip are observed compared. Bond stress-slip response obtained numerically validated with experimental data empirical equations available from literature. The full overestimates response, providing higher stress. In models, good agreement numerical stress Stress–slip responses. equation proposed by Murcia-Delso Shing (2014) found overestimate peak
