Reinforced concrete walls are often introduced into multistory buildings to
resist lateral forces which can be exists due to winds or earthquakes. In
the present study, six models I–section shear wall models were tested under
combined action of a constant axial load and reversal horizontal increased
loading until failure. The study has investigated the effects of some
parameters such as, the height – to – width ratio, the compressive strength
of concrete, and the variation of main flexure reinforcement ratio on the
behavior of high - strength concrete shear walls. The obtained results
from the tests have helped to identify the causes of wall failure modes. The
test results included the determination of ultimate load, deflection, mode of
failure, crack pattern, ductility, stiffness, and energy absorption.
