Abstract :
In this paper a study on behavior of ten under-reinforced concrete beams with fibers (Steel and Glass-fibers), and also with or without G.I wire mesh wrappings under flexural loading is presented. In general, addition of fibers improves the bending strength and ductility of the composite. The G.I mesh wrappings will provide the additional confinement to the fibrous concrete matrix. The test results show that flexural strength and ductility of confined fiber reinforced concrete beams is improved compared to un-confined fibrous beams. It is also observed that the enhancement in flexural capacity and ductility is more in beams with steel fibers than Glass-fibers.
