| Abstract: | The damage indices of three cyclic loading reinforced concrete column specimens were calculated according to three known seismic damage index models, which were based on accumulative damage, deformation-energy and structural stiffness, respectively. Based on the calculation results, test data and damage characteristics in the test process. the validity of these damage index models on evaluation of damage degree of RC columns under seismic loading were analyzed and compared. The existing problems on the research of seismic damage index and some suggestions for the future research were brought forward finally. |
