Paper Title:
Simulation on Expanding Crack of Reinforced Concrete Based on Franc2d
  Abstract

It is a key point of durability deterioration to reinforced concrete structures that protective layer concrete cracking, so it is essential to assess the durability limit state to determine the critical corrosive ratio. In this paper the Franc2D tool has been used to simulate the corrosive expanding process of protective layer concrete in reinforced concrete structure, and the slope change of the ρ-CMOD curve has been used as the basis to determine the critical corrosive ratio, then the effects of stirrups to critical corrosive ratio and the corrosive expanding crack width has been studied. It has been showed a linear relationship between the corrosive ratio and crack width, and appearance of corrosive expanding cracks has been delay with the stirrups, on the other hand crack propagation speed can be reduced with the stirrups across cracks effectively.
