| 要旨 | This study proposed a method to simulate crack propagation due to rebar corrosion based on Rigid-Body-Spring Method (RBSM) in which rebar is modeled by beam element in order to reduce computational cost for the analysis of structural level. The effects of local corrosion around the rebar as well as penetration of corrosion products into cracks were taken into consideration in the model. The applicability of the method was verified by comparing with experiment using single-rebar specimens with different rebar diameters, cover thicknesses and specimen sizes. Analytical results showed a good correlation with experimental ones not only in terms of crack propagation tendency but also crack width values. |
