#### Rebar Estimating Methodologies

2017-5-25 · presented in Table 2 and the difference in estimation of rebar diameter is 1.6% to 5.75%. Further elaborative studies are required in estimating the rebar diameter on concrete structural elementswith multiple rebars by considering the effect of spacing of rebars, interference effect, scattering of signals, etc. [8].
