Abstract
The main objective of the current research is to study the
behavior of reinforced concrete R.C columns strengthened with
ferrocement jacket and subjected to axial load. The experimental
program includes ten R.C columns. Three columns were used
(C1, C2and C3) with an aspect ratio of (1, 1.56, and 2.04), respectively
used as a control column, and the remainder of columns were
strengthened with ferrocement jacket. The parameters studied were the
thickness of the ferrocement jacket, the number of wire mesh layers,
and the aspect ratio of the cross-section of the columns.
The obtained results showed that as the wire mesh layers increase
a significant increase in the nominal compressive strength of
the strengthened columns was satisfied. Moreover, a similar trend of
the effect of the number of wire mesh layers was obtained due to
increasing the ferrocement thickness. On the contrary, increasing
the aspect ratio of the columns resulted in decreasing the nominal
compressive strength of the strengthened columns. Furthermore,
the ductility, toughness, and stiffness of the strengthened columns are
improved by increasing both the number of wire mesh layers and
the ferrocement thickness. However, the ductility, toughness, and
stiffness of the strengthened columns decrease as the aspect ratio of
the strengthened columns increase.
