Self-sensing FRP rib-reinforced concrete column
The invention discloses a self-sensing FRP rib-reinforced concrete column, which comprises the following steps: slotting a column corner region of the concrete column and embedding a self-sensing FRP rib; wrapping the periphery with a constraint material; and improving the structural rigidity of a rebar after yielding, and reducing residual deformation. The self-sensing FRP rib sleeves the outside of an aluminum pipe in a junction region of a column body and a foundation; stress concentration is reduced; premature fracture of the self-sensing FRP rib is prevented; a built-in sensing fiber connected with the self-sensing FRP rib forms a monitoring system; the damage to the structure after an earthquake is evaluated; and a reliable basis is provided for repairing. According to the technical scheme disclosed by the invention, control on structural damage and quantitative description of 'repairable level under moderate earthquake action' or 'repairable level under strong earthquake action' can be achieved.
