The force/movement characteristics of bridge bearings are classified into three groups and the implications of this classification are examined in terms of the compound stiffnesses of piers. The modelling of the foundation as an elastic continuum and its influence on the compound stiffness is discussed. The interactive effects of external and internal forces on the deck are considered in relation to the distribution of forces and movements at supports and the available analytical techniques are extended to examine some unusual features in the distributions of movements at joints and braking forces on piers measured on bridges on service.
