Abstract: The current bridge design codes follow a force-based design methodology, without any check on the displacement. In this methodology, the effect of inelastic energy dissipation is taken into account indirectly using a 'Response Reduction Factor' or 'Behavior Factor'. Contrary to buildings, the energy dissipation in bridges takes place in the piers. The capacity of a pier to dissipate energy depends on reinforcement detailing in the plastic hinge region. Different national codes differ in the values of response reduction factor and reinforcement detailing guidelines in piers. A comparative study is conducted on two bridges with different spans and heights to study their collapse probabilities at maximum considered earthquake (MCE). It is observed that seismic load combination factor, response reduction factor, P-Δ effect and ductile detailing provisions play crucial roles in the seismic capacity and collapse probability of bridges. © 2018 11th National Conference on Earthquake Engineering 2018, NCEE 2018: Integrating Science, Engineering, and Policy.
