MESOSCALE SIMULATION ON STRUCTURAL PERFORMANCE OF RC SHEAR WALL WITH DIFFERENT AXIAL COMPRESSION RATIOS
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.
