Abstract:The calculation method of shear wall axial compression ratio was discussed, and some problems in calculation method of shear wall axial compression ratio according to current code were pointed out. The distribution characteristics of axial internal forces of shear wall were introduced,  the calculation method of “sectional axial compression ratio” under gravity load representation and horizontal earthquakes was put forward, and the suggestion of the shear wall axial compression ratio limit was given. An engineering example was offered to explain the application of the method. The results show that this method is more reasonable, and is more conducive to giving full play to the seismic potential of shear walls.

Keywords:shear wall axial compression ratio; calculation method; sectional axial compression ratio; compression ratio limit
