The size effect on the seismic performance of conventional reinforced concrete columns has been observed in terms of flexural failure and shear failure.
Under earthquake loading, slender columns experience flexural failure, and short columns experience flexure-shear failure and shear failure.
However, the effect of section size on the seismic performance of high-strength reinforced concrete columns under the conditions of different shear span-to-depth ratios requires further confirmation.
For this purpose, six high-strength reinforced concrete columns with shear span-to-depth ratios of 2 and 4 were subjected to cyclic loading in this study.
The experimental results indicated that relative nominal flexural strength, energy dissipation coefficient, factor of safety, and local factor of safety all exhibited a strong size effect by decreasing with increasing column size.
Furthermore, the size effect became stronger as the shear span-to-depth ratio was increased, except for average energy dissipation coefficient.
The observed changes in the factor of safety were in good agreement with the Type 2 size effect model proposed by Bažant.
Thus, based on the local factor of safety and Bažant’s Type 2 model, the code equation for moment capacity of different shear span-to-depth ratios was modified to provide a consistent factor of safety regardless of column size.
