A displacement‐based design procedure for continuous concrete bridges is proposed which can be incorporated into a performance‐based design philosophy. The procedure is applicable to multi‐degree‐of‐freedom bridges with flexible or rigid superstructures, and for varying degrees of abutment restraint. The background and development of the design procedure is presented first, followed by a series of examples and validation studies using dynamic inelastic time‐history analysis. The procedure is applied to the transverse response of bridge structures; however, it is equally well‐suited for longitudinal response. The results indicate that the process is able to capture non‐linear deformation patterns and thus reasonably control damage. Copyright © 2001 John Wiley & Sons, Ltd.
