Abstract

In order to study the effect of strain rate on reinforced concrete columns under earthquake action, two group reinforced concrete columns with constant axial load were subjected to cyclic uniaxial and biaxial tests with different loading rates. The experimental program is described. Then, tests results about reinforced concrete columns dynamic behavior are presented and discussed under uniaxial or biaxial tests. Based on the fiber model theory and Timoshenko beam theory, considering the strain rate sensitivity of steel and concrete, a new three-dimensional beam element is proposed. According to the calculation model of reinforced concrete columns mentioned above, the dynamic performances of reinforced concrete columns are simulated which show a good agreement with the test results.
