DUCTILE DESIGN OF BRIDGE PIERS
A review of some recent New Zealand research on the ductile design of reinforced concrete bridge piers is presented. The main part of the research described has been sponsored by Roads Board, and has been reported to the National Roads board during the period 1974-78. The research was concerned with two main aspects of the seismic design of ductile bridge piers. The first aspect involved the inelastic dynamic analysis of bridge structures, including the effect of soil-structure interaction, to establish the ductility demand of typical reinforced concrete bridge piers when responding to severe earthquakes. The second aspect concerned analytical and experimental innvestigations of reinforced concrete bridge piers in order to establish the available ductility capacity and hysteretic energy dissipation. A study of the quantity of spiral reinforcement required to confine the concrete and to prevent buckling of longitudinal bars was an important part of the investigation. The conclusions reached are summarized in form useful to practising bridge designers. (a) (TRRL)
