On this basis, methods to assess the durability of fiber-reinforced concrete structural structures subjected to long-term static load, which causes creep in fiber-reinforced concrete until its destruction, have been developed. Analytical dependences for predicting the strength and crack resistance of hybrid fiber concretes are obtained. A method and a criterion for AE-optimization of high-strength fiber volume fraction in concrete composite was developed to ensure its maximum strength based on identification of failure mechanisms and determination of tensile strength - ratio of tensile strength of composite σB to stresses σAE of generation AE signals accompanying shear failure mechanisms.
