The paper is on the basis of the researchful achievement in the world, the reinforced mechanism of woven-fiber-grid-reinforced concrete beams was studied in which elastic properties , flexural properties and interface performance. On the choice of the researchful methods, it combines the meso-mechanics method , finite element method and transformative energy method in this research work. Especially, the reliability and powerful function of image visualization in the finite element analytical software ANSYS are used for stress distribution of the woven-fiber-grid-reinforced concrete beams.The innovation of the study consists in the following:1 This study adopts woven fiber grid to reinforce concrete beams. Undoubtedly , it is a new attempt in the field of concrete research.2 This study attempts to substitute woven fiber grid for steel in concrete . After laying woven fiber grid in concrete beams, their flexural strength and flexural toughness index are greatly improved. In addition, woven fiber grid can overcome the shortcoming of steel' s easy corrosion and high density .So it is also a new researchful tendency to substitute woven fiber grid for steel in concrete. |
