Paper Title:
Inelastic Spectrum Method Applied to Evaluate Seismic Safety of Bridge Structures
  Abstract

For the past few years, Push-over analytical method was regarded as a new evaluation method for seismic resistance capacity of structure in some advanced countries. 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. The elastic spectrum from the Highway Engineering Seismic Design Code (JTJ 004-89) was improved in order to take the inelastic effect into account. The inelastic demand spectra were derived by means of Vidic's strength reduction factors. 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.
