Abstract

Curved and/or skewed bridges are very common on highways across the country. These bridges are more vulnerable to seismic than typical straight ones. The current specifications do not provide enough coverage for the curved and skewed bridges on progressive failure risk. Under the joint impact from post-seismic traffic and partial damage of some members from seismic, the progressive failure risk will increase depending on the intensity of seismic and traffic at the time. It is thus important to evaluate the progressive failure risk of vulnerable curved and skewed bridges immediately after the seismic occurrence. However, such a simulation tool which can enable progressive analysis of curved and skewed bridges subjected to traffic and seismic is not available.
