Abstract: As a typical non-homogeneous composite material, the microstructure of concrete will
affect the mechanical behavior and failure characteristics of reinforced concrete shear walls.
Numerical concrete generation technology is used to simulate the microstructure of the lower
part of reinforced concrete shear wall components. The homogeneous macroscopic element is
used to simulate the upper part of the component to establish a multiscale model. The
numerical analysis of the model under load is carried out and compared with the test results of
the corresponding components. Based on multiscale modeling technology, the effects of
boundary size on the mechanical behavior of the components were further studied. The results
show that the multiscale model can better simulate the mechanical behavior and damage
characteristics of reinforced concrete shear wall components; the boundary size of the model
has a little influence on the peak post-ductility of the components.
