More available information can be obtained from Push-over analysis than from elastic static, even elastic dynamic analysis and the method is easy to be operated. Its basic elements, analysis process and the state-of-the-art are reviewed and the elastic spectrum from the Chinese Seismic Resistance Design Code for Highway Engineering (JTJ 004-89) was improved in order to take the inelastic effect into account herein. The inelastic demand spectra for four site conditions were derived by means of Vidic's strength reduction factors. The factors were studied in detail. By comparing capacity curves of bridge structure with the demand elastic spectrum, the earthquake resistance of bridge structure can be estimated. Furthermore, it is applied to evaluate seismic resistance capacity of a real bridge example in this paper. The results show that Pushover method can replace inelastic dynamic history analysis method in some cases.
