Study on Flexural Bearing Capacity of Unbounded Pre-Stressing Composite Slab

Abstract:

For the purpose of correct theoretical evaluation about the bearing capacity of unbounded pre-stressing composite slab. According to the construction methods and basic principles of unbounded pre-stressing composite slab, basic assumption of composite slab flexure calculation is defined; under the elastic stage, composite slab section stress-strain relationship at each stage was analyzed, as well as resolving the stress increment problem of vivo unbounded pre-stressing steel bar in the limit stage, and flexure bearing capacity of composite slab in various destroy mode in the limit stage was produced by the limit equilibrium method. The practicality of composite slab flexure bearing capacity formula was tested and verified by specific examples, provided a theoretical foundation for the practical engineering application.
