Abstract—The experimental tests, carried out on the
reinforced concrete walls under a horizontal, a cyclic and a
seismic loading, have all shown that these RC walls have a more
performing behavior when the steel bars are placed according
to the direction of the principal stresses. However, these
principal stresses are directly connected to an angle of
inclination which is often to seek. The intent of this study; is to
find the most possible adequate angle of inclination of the
diagonal bars in order to improve the mechanical performance
of the squat RC walls and also to evaluate the contribution of
the diagonal web reinforcement comparing to the conventional
web reinforcement. For that, we used a local approach by
modeling reinforced concrete walls in 3D requested under a
horizontal loading. The numerical model used for the modeling
of the concrete is the damageable elastic-plastic model of
ABAQUS which makes it possible to visualize the damage at the
local level and to determine the mode of rupture. On the other
hand, for the bars of steel an elastic-plastic model is used. The
results of the simulation in terms of damage, stress and
deformation are collected and they put forward the mechanical
performance of the reinforcement following the direction of the
principal stresses compared to the traditional reinforcement.
