Reinforcing bar cross-section defect rate estimation method, estimation device and estimation program

摘要

PPROBLEM TO BE SOLVED: To accurately estimate the corrosion state of the reinforcing rod in concrete in a non-destructive manner. PSOLUTION: When the value of the surface crack width L of cover concrete is given, an influence function f(c) and influence coefficient (c) of cover thickness of a reinforcing rod, an influence function f() and influence coefficient () of diameter of the reinforcing rod, an influence function f(s) and influence coefficient (s) of presence of a distributing bar, and an influence function f(a) and influence coefficient (a) of position of the distributing bar, are used to calculate a cross sectional loss factor W of the reinforcing rod according to a formula: W=f(c)f()f(s)f(a)L+(c)()(s)(a).
