| 要旨 | In this paper the size effect in concrete and reinforced concrete structures is predicted by computer simulation of failures using the program ANACS (Advanced Nonlinear Analysis of Concrete Structures). The material model is based on the fictitious crack modeling with two orthogonal rod elements. The fracture of concrete is modeled based on the fracture energy-related softening. This enables a modeling of the size effect in cases of flexure and shear types of failure in concrete and reinforced concrete structures. Using the arc-length method post peak behavior can be predicted well even for snap back instability. Examples of flexure failure of plain concrete beams, and shear failure of reinforced concrete beams are shown. |
