Abstract：Here, in order to study size effect mechanism on RC short column shear performance under cyclic load, using 3-D rigid spring element method and based on beam-arch model, anti-shear actions of RC short columns with 3 different section sizes were decomposed. The results showed that the 3-D rigid spring element method can better simulate shear performance of RC short columns with different section sizes under cyclic load; when the ultimate load is reached, the shear strength defined as nominal shear stress gradually decreases with increase in section sizes; compared with the monotonic load, the size effect varies less after one cycle, while the size effect is more obvious after two cycles during short column close to failure, the main cause is due to anti-shear action of the arch model sharply dropping.
