Because significant difference between normal concrete and fiber reinforced ultra-high strength concrete under tension and compression, bond behavior also have significant difference. Based on the finite element analysis of bond test specimens, crack initiation and propagation process were investigated. Analysis results have been validated with test results and crack initiation stress was investigated.
