- Synopsis
- In short fiber reinforced concrete, tensible stresses sre transmitted in crack faces because of the bridging effect of fibers, thereby offering a higher ductility of concrete. The tensile failure characteristic, discussed in this paper, is therefore a key parameter when evaluating the properties of short fiber reinforced concrete. In addition, new application techniques of short fibers are presented here for enhancing the shear strength and seismic performance of concrete structures. These techniques resort to satisfactory crack dispersing and increased energy absorbing capabilities provided by the bridging effect of fibers.
