FIELD: construction engineering. SUBSTANCE: this relates to precompressed reinforced concrete structures. Reinforcement framework of building structure is made up of longitudinal reinforcing members which are connected by their ends with lateral reinforcing members. Longitudinal reinforcing members are bent along arch and located in pairs over perimeter of building structure relative to axis of symmetry which is parallel to direction of applying compression force. Convexities of longitudinal reinforcing members which are bent along arch are directed in each pair towards each other that is towards axis of symmetry. Application of aforesaid reinforcement framework allows for increasing load-bearing capacity of precompressed building structure without enlarging metal-input in reinforcement framework due to combined functions of longitudinal and indirect reinforcement in longitudinal reinforcing members which are bent over arch. EFFECT: higher efficiency. 5 dwg |
