This study is to discuss the issues with the change of the angle of inclination when forming the tension-field in the high-rise structures under the lateral force. The high axial and flexural column forces caused by the high overturning moments would decrease the overall stiffness of the shear wall, and the change of structural mechanism may induce the change of the angle of inclination. So, the analysis study was performed with four finite element models, 3, 9, 14 and 20 stories. Each model was classified in shear and flexure mode by comparing to the strength of estimates calculated by the equation and analysis results. In the model of shear deformation mode, it was showed to form constant angle to cause tension-field by checking the principal stress vector.; whereas, the column plastic hinge occurs bending deformation in flexural mode and the change of tension-field according to the mechanism showed highly differences from the existing theory.
