In order to lack of space, the usage of underground structures for passive defense are expanded.. therefore the selection of materials in consideration of economic and safety is necessary. Concrete and shotcrete are used extensively in underground structures. In addition, shotcrete has been used extensively in most parts of the world for a wide variety of applications including new construction, in the repair and rehabilitation of older and deteriorated structures, in slope stabilization, as retaining walls for large excavations, and for tunnel lining, etc. Concrete and shotcrete are brittle materials, hence reinforcement of them to achieve high ductility is very important. Addition of steel bars and steel mesh aids to converting the brittle characteristics to a ductile one. But in long -term in humid condition steel is rusted that lead to creatio a osteoporosis concrete and shotcrete , So it is necessary to replace other artificial materials instead of steel. In addition, in steel-mesh applications, the installation of steel mesh (SM) can be difficult, time consuming, hazardous and expensive. Also, lining quality can be poor, i.e., no uniform bond between shotcrete and rock, forming low-quality shadow areas behind the wire, and badly placed reinforcement due to irregular mesh positions, etc. By contrast, fibers eliminate the need for conventional concrete reinforcing steel, welded wire mesh or the chain-link mesh, and this alone results in a significant enhancement of the ease of shotcrete placement. In addition, fibers impart toughness or energy absorption capability to hardened shotcrete, resulting in improved deformability. In this research for reinforcement of concrete and shotcrete we use Barchip fiber, advantages include no rusty, a reduction of cracking, and enhancements to ductility, impact resistance, and toughness. In addition Reduced fire damage (anti-spalling), along with economic benefits of reduced placement labor and overall savings in reinforcement costs. In this research the effect of barchip fiber on ductility behavior and strength properties of concrete and shotcrete are studied. Results has shown that barchip fiber have significant effect on shear strength, tensile strength , adhesion strength and ductility behavior of concrete and shotcrete, in addition barchip fiber increase friction angle, but reduced Compression Strength that with added microsilis the effect of barchip fiber o Compression Strength is decrease. The results of direct shear test show that with increase fiber, the increase of shear strength in concrete is up to 13 % and in shotcrete is uo to 15%. In addition, Adhesion strength and Friction angle also increase up to 6% and 13 % for concrete and 16% 10% for shotcrete. In this research tensile strength of concrete and shotcrete that reinforced with Barchip fiber, is defined with Brazilian test. The results show that with increase fiber, the increase of Tensile strength is up to 20% rather than plain concrete and shotcrete. Rebound of fiber in shotcrete is a important parameter in consideration of economic, therefore determination of rebound is very important. In this research measure of Barchip fiber rebound is about 12%. Barchip fiber have low gravity that lead to reduced rebound them in shotcrete.
