Part of: Structural Engineering in Natural Hazards Mitigation


Structural safety of reinforced concrete bridge piers supporting highway traffic is studied. Reliability indices for flexure, shear, and combined flexure and axial load limit states at ultimate are evaluated for a typical hammerhead pier. The statistical parameters of the resistance are determined using simulation and integration methods. The probabilistic load models are compiled from the available literature.
