Calculation method for flexural capacity of CFRP (Carbon Fiber Reinforced Plastics) cloth reinforced light steel-fiberboard composite floor
The invention discloses a method for calculating the flexural capacity of a CFRP (Carbon Fiber Reinforced Plastics) cloth reinforced light steel-fiberboard composite floor slab, relates to the technical field of composite floor slab reinforcement, and particularly belongs to a method for calculating the flexural capacity of the CFRP cloth reinforced light steel-fiberboard composite floor slab. Comprising the following steps: making a basic assumption on a section stress state when the light steel-fiberboard composite floor is damaged; establishing a computational formula of the flexural capacity of the non-CFRP cloth reinforced light steel-fiberboard composite floor; establishing a relation function between the number of bonding layers of the CFRP cloth and the reinforcing coefficient of the CFRP cloth and a relation function between the prestress of the CFRP cloth and the reinforcing coefficient of the CFRP cloth; establishing a reinforcement coefficient function expression of the CFRP cloth; and determining an undetermined coefficient value in the CFRP cloth reinforcement coefficient function expression to obtain a computational formula of the flexural capacity of the CFRP cloth reinforced light steel-fiberboard composite floor. Certain theoretical reference is provided for design and engineering application of the CFRP cloth reinforced light steel-fiberboard composite floor, and it is guaranteed that the bearing capacity design requirement can be met by adopting the composite floor.
