Abstract

In this thesis a capacity spectrum method for hybrid sliding-rocking post-tensioned segmental bridges is proposed. A simplified model and two detailed models are derived for the conducting pushover analysis on the structure. The derived models are compared with experimental results and are used to conduct a parametric study of the design variables pertaining to hybrid sliding-rocking post-tensioned bridges. Next a capacity spectrum method for design is proposed which uses the detailed model. The proposed design method is then verified using nonlinear dynamic analysis on the structure using the detailed model for a given hazard. Results from the study show that the proposed Capacity spectrum design method predict the performance of the structure reasonably well when compared with nonlinear dynamic analysis.
