要旨 
A higher order continuum method, namely the gradient plasticity approach is applied to analyze the fracture and crack propagation of reinforced concrete members in tension. Separate finite element modeling is done for each constituents of reinforced concrete  concrete, reinforcement and the bondslip mechanism. A gradient enhanced continuum approach was used for concrete. Analyses was performed to investigate the capability of the gradient plasticity approach to produce discrete cracked zones at regular spacing. The effect of different reinforcement ratio on crack spacing and on the average stressstrain relation of steel is studied.
