Abstract [en]

A numerical code RFPA3D(Three-Dimension Realistic Failure Process Analysis) is employeel to simulate the three-dimensional failure process of reinforced concrete under uniaxial tension. Then the analysis focuses on the stress distribution during the failure process and failure mechanism of the concrete and reinforcement. The numerical tests indicate the periodically distributed fracture in the reinforced concrete structure and the numerical analysis reproduces the complete process of the fracture initiation, infilling and saturation, 3D numerical tests with different thickness of concrete covers reveal that the eritical value of the fracture spacing increases and the crack numbers decreases with increasing ratio of the thickness of the concrete cover to that of the steel bar
