Inelastic Displacement Spectra for Displacement-Based Seismic Design of High-Speed Bridge Pier

摘要：

　　The inelastic displacement spectra is established based on the elastic displacement spectra and the strength reduction factor,the calculation process of Displacement-Based Seismic Design (DBSD) is presented in this paper,the DBSD of high-speed railway bridge piers is conducted to verified the method.The calculation results show that,at the same performance target,the pier height is taller,the cross-section is bigger; at the same pier height,the performance target is higher,the cross-section of pier is bigger; according to the reinforcement ratio with the different pier height and performance target are the lower limit of calculation value,it mean that the lateral reinforcement ratio of piers can only meet the detailing requirements.
