Probabilistic performance-based seismic design of highway bridges in Canada

The philosophy for designing structures to resist earthquakes has largely evolved from initially avoiding collapse to more recently controlling structural damage. The current concept of seismic design of highway bridges in Canada is based in assuring structural performance, giving more control to owners and regulatory agencies in the decision-making process. This philosophy has progressed significantly in academia achieving frameworks that are capable to handle important uncertainties, such as those involved in seismic hazard. Nonetheless, practicing structural engineers and current standards still neglect the propagation of uncertainty in the design process, showing a natural gap between the state-of-the-art and the state-of-practice. This project aims to push the limits of practicing earthquake engineering towards a design philosophy that handles performance in terms of probability, providing engineers with useful tools and concepts that allow the design of more economic and yet reliable transportation infrastructures.
