Zusammenfassung:	FIELD: construction engineering; bridge structures. SUBSTANCE: proposed T-shaped or trapezoidal beam module is made from concrete with principal tendons located in lower stroke; longitudinal channel is provided with cable reinforcement which is formed by hollow or curvilinear insert made from polymer material and/or thin-sheet corrugated metal, steel for example; height of beam module is equal to 1/15-1/35 of its span; additional hollow inserts, 65-160 mm in diameter made from polymer or thin-sheet corrugated metal are provided at distance from longitudinal channel exceeding diameter of said insert; these inserts are used for receiving high-strength cable reinforcement. EFFECT: improved service characteristics; enhanced reliability and durability; reduced usage of materials; optimization of distribution of load over length of beam module. 4 cl, 2 dwg
