“…Rui [13] studied the fatigue bond performance of BFRP reinforcement and RAC by drawing test and revealed the influence of design parameters on bond stiffness, bond strength, and residual bond strength. Kim et al [14] applied BFRP as grid cloth to the reinforcement and repair of existing concrete members and conducted relevant experiments. e results showed that BFRP grid cloth could effectively delay the failure time of damaged concrete members.…”

To explore the clustering phenomenon of discontinuous fibers in composite materials, this paper deduces the fiber uniform distribution coefficient and analytical expressions of fiber clustering content based on fractal theory and establishes a tensile strength prediction model of fiber/epoxy resin composite materials containing cluster fibers. With basalt fiber/epoxy resin composites (BFRP) as an example, this paper analyzes the tensile strength law of BFRP under fiber clustering effect. The results show that when the fiber volume fraction is constant, the tensile strength of the composite in the presence of agglomerated fibers is only related to the fractal dimension of the circumference and cross-sectional area of the inner fiber agglomerate. The calculated value of the composite tensile strength based on fractal theory is lower than the experimental value, but closer to the experimental value than the approximate method. The research conclusions can provide theoretical support for strength prediction of fiber/epoxy resin composites.

The study aims to explore the causes of early cracks in prefabricated bridges and propose repair measures. The stude designs a test first. Analysis of the mix proportion and uneven shrinkage of concrete shows that, in concrete, the ratio of air content to water-binder is a quadratic parabola, the fly ash and water binder ratio have a linear relationship, and slurry collection ratio and the water-binder ratio is inversely proportional. The test results suggest that the cracks of bridges are caused by the decrease of relative humidity in concrete. Afterward, some corresponding repair measures are put forward to safeguard the prefabricated bridges.
