Abstract: The research described by the current dissertation was focused on studying the mechanical behavior of the wired-mesh gabions under axial compression load. And it is important to mention that there is no specific standard for using gabions as structural elements It is a unique study because using this type of construction usually does not take into consideration the study of the structural behavior of these boxes, and here many of the problems facing the construction of this kind appears. This research studied the behavior of these boxes through laboratory experiments. 18 samples of fixed boxes of dimensions 20 * 20 * 20 cm were exposed to axial load using unconfined compression machine. Two parameters were tested changing the diameter of steel bars and also the aggregate size diameter that were used in the design process of these boxes. Stress-strain diagrams were monitored. Results showed as the size of the aggregates is smaller, ultimate strength increased, modulus of elasticity increased On the other hand, results showed that ultimate strength considerably increased increasing steel-bar diameter. Furthermore, lab experiments showed that the behavior of the gabion is highly sensitive to manufacturing quality, It was found that in some cases the two boxes with the same specifications ( steel bar diameter, aggregate size distribution) gave a different results due to the difference in manufacturing quality . It was studied the vulnerability these cubes prone force and what is the influence of changing of steel bars diameter on the strength of the box, as well as the influence of the aggregate size on the strengthening of that box. The labor experimental results indicate the deformation mode of a loaded gabion structure and the maximum stress that the box sustain.
