Crack propagation of the short cut fiber reinforced concrete due to drying shrinkage was investigated. Shrinkage crack tests using specimens with external restriction were performed. The relation between tensile stress and crack width of the specimen was measured and this relationship was compared with the tri-linear tension softening diagram. Tri-linear tension softening diagram was approximated to the poly-linear tension softening diagram which was analyzed by the data of a load-load point displacement curve obtain from three-point bending test. Analysis method of crack propagation of the shrinkage crack specimen was proposed based on the crack equation analysis method using a variant tri-linear tension softening diagram according to the concrete age.
