Abstract: |
The performance based design provisions of the 2014 Canadian Highway Bridge Design Code (CSA S6-14) have been applied to assess the seismic design of a three-span prestressed reinforced concrete bridge in Vancouver Island, British Columbia. Response spectrum and nonlinear time- history analyses of the bridge at 10%, 5%, and 2% probabilities of exceedance in 50 years hazard levels, and a static pushover analysis were carried out. Soil-structure interaction was considered assuming two soil conditions, corresponding to site classes C and D of CSA S6-14. The seismic performance of the bridge was also evaluated using the recently updated performance criteria in the 2016 BC MoTI Supplement to CSA S6-14. It was observed that the bridge design satisfied all of the performance criteria in both documents at all hazard levels and for both soil conditions, except for the CSA S6-14 criteria at 10% in 50 years probability of exceedance hazard level on site class D. |
