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, C2, and C3) with an aspect ratio of (1, 1.56, and 2.04), respectively as a control column, and the remainder of the columns were strengthened with a 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 column.
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.
Keywords- Columns, Ferrocement, Reinforced Concrete, Strengthening, Wire Mesh.
