Purpose: To consider the possibility of using composite rebars in the construction of square-section driven piles. Methods: Analytical and experimental studies have been carried out on how the type of rebars used in concrete driven piles affect strength and rigidity in the process of unloading. Results: The article presents the results of calculations of the short-term strength reserve coefficients of concrete driven piles reinforced with fiberglass composite rebars during their transportation. A strong dependence of the maximum allowable force value on its orientation during pile indentation has been established. The results of experimental driving of piles reinforced with composite rebars are presented. Practical significance: It has been established that piles reinforced with composite rebars do not differ in their properties from those reinforced with traditional metal armature. The economic effect of replacing traditional metal reinforcement with composite rebars reflected in the cost reduction of the final product (piles) has been determined.
