High-strength reinforced and functionally-graded concrete beam
The invention relates to a structure of a building member and a material, particularly relates to a high-strength reinforced and functionally-graded concrete beam and belongs to the technical field of building materials. The high-strength reinforced and functionally-graded concrete beam is mainly characterized in that common concrete and a high-toughness fiber-enhanced cement-based composite material are combined in a layering manner; the common concrete is adopted for the pressed area of the concrete beam; the high-toughness fiber-enhanced cement-based composite material is cast in a pulled area in the whole longitudinal-length range of the beam or the specific beam section; and interface-area treatment is adopted for a combined area of the common concrete and the high-toughness fiber-enhanced cement-based composite material. The high-strength reinforced and functionally-graded concrete beam has the advantages that uniform transition of the material system on performance is realized, discontinuous weak areas on the interface are eliminated, the bearing capability of the structure is effectively improved and the completeness and the stability of the whole structure are ensured.
