Through the experimental tests on 6 steel reinforced high-strength concrete columns under low cyclic horizontal loads, the influence on anti-seismic performance of the columns under different axial compression ratio, stirrup ratio and steel form is analyzed, and that anti-seismic performance of the columns is affected not only by axial compression ratio, but also by steel form. For steel reinforced high-strength concrete columns with different steel forms, the limit values of axial compression ratio may be adjusted, while the influence of stirrup ratio is not prominent.

High Strength Concrete Columns

The influence on columns behaviors of slenderness ratio are analyzed, and the influence on columns’ anti-seismic behavior of axial compression ratio, stirrup ratio and steel form are analyzed through the test on bearing capacity and level load of low cycle reverse of steel reinforced high-strength concrete columns. The bearing capacity of the long columns reduces along with the slenderness ratio increasing and augments along with concrete strength increasing. Probability of suddenly destruct increases along with the column slenderness ratio augmenting through the test. In addition, anti-seismic behavior of columns are effected not only axial compression ratio, but also steel form. Axial compression coefficien of the steel reinforced high-strength concrete columns with different steel form may be adjusted, however, the influence of stirrup ratio is very little on anti-seismic behavior of columns.
