profiled column frame - shear wall;  modal analysis;  elastic time history analysis;  Inter-floor displacement

Due to the improper layout of the shear wall, it is not uncommon for the structure of the special-shaped column and frame shear wall in service to undergo serious torsional deformation or even collapse under the action of earthquake. By adjusting the shear wall layout scheme in the actual engineering of a special-shaped column frame and shear wall structure, the author carried out modal analysis and elastic time history analysis of the improved model, and studied the influence of different plane arrangements of shear wall and special-shaped column on seismic response. It is found that the seismic performance of the improved model is significantly improved, the bottom shear force does not change much, the maximum floor displacement and structural self-resonance period are significantly improved, the maximum floor displacement value is reduced by 14.4%, and the self-oscillation period is reduced by 4.34%.
