Abstract
Based on orthogonal completeness and mechanical equilibrium, the physical parameters of materials are further considered, and the deformation decomposition method is improved and applied to orthotropic structures. The method is realized by compiling ANSYS-MATLAB computer algorithms, and verified by strain energy analysis and experimental results. It not only quantitatively identifies tensile, compressive, bending and shear deformation energies of orthotropic structures, but also visualizes the regions dominated by the aforementioned fundamental deformation energies. Furthermore, the influence of the horizontal and vertical elastic modulus ratios of coupling beams and wall-columns on the seismic performance of orthotropic shear walls with different opening sizes is discussed. The results show that the ductility of the coupling beam and the wall-column is improved by appropriately reducing the horizontal and vertical elastic modulus ratio of the coupling beam, and the effect on the wall-column is weakened with the reduction of the opening size. But the lateral resistance of the shear wall is weakened. The wall-column ductility is improved by properly increasing the horizontal and vertical elastic modulus ratio of the wall-column, but the lateral resistance of the shear wall is weakened.
