Abstract:In view of the characteristics of complex stress and high tensile stress in anchorage zone of crosstensioned prestress concrete pavement, the experimental study on local compressive performance of fiber reinforced concrete is carried out, and the typical failure mode of fiber reinforced concrete under local compressive load is obtained. Furthermore, the influence of the supporting conditions and fiber content on the cracked and ultimate strength is analyzed. The failure mechanism of fiber reinforced concrete under local compressive load is revealed. Additionally, the enhancement coefficient of local compressive bearing capacity of fiber reinforced concrete with ducts is obtained based on the pullrod model. The results show that the supporting conditions and fiber content of fiber reinforced concrete have significantly influence on its local compressive bearing capacity and failure mode. The local compressive bearing capacity of fiber reinforced concrete increases gradually with the increase of fiber content for the same support condition. The local compressive bearing capacity of the fiber reinforced concrete under full supporting condition is significantly higher than that under partial supporting condition for the same fiber content. The ratio of local compressive area and the size of reserved ducts significantly influence the enhancement coefficient of local bearing capacity.
