To evaluate and quantify the effect of the axial compression ratio on the seismic performance of reinforced concrete walls, a comprehensive statistical analysis with 474 sets of experimental data was conducted. Stipulated limits on the axial compression ratio and their evaluation methods in various design codes were analysed and compared. Based on the results of these analyses, methods for calculating the effective axial compression and the limiting value of the axial compression ratio for reinforced concrete (RC) structural walls stipulated in the Code of Practice for Structural Use of Concrete 2013 may be amended and improved on a more scientific basis. Recommendations are made for possible amendments to the provision of design or detailing for ductility of structural walls in Clause 9.9.3 of the Hong Kong structural concrete code 2013.
