Current codes of practice for the design of tall concrete chimneys provide conservative aseismic design guidelines in high seismic regions. A lack of experimental data related to the cyclic behaviour of chimney structures to severe earthquake excitation has resulted in the assumption that such structures are brittle and must be designed in the elastic range. This design approach results in expensive structures and is not consistent with the design philosophy commonly adopted for general structure which permits some inelastic response at the ultimate limit state event. A research program funded by the CICIND organisation has been undertaken to investigate the inelastic cyclic behaviour of tall reinforce concrete chimneys using both experimental and analytical techniques to determine whether the behaviour is brittle or ductile. The research has been divided into three parts; (a) overview of earthquake ground motions, review of the earthquake response of structures and review of chimney design code provisions, (b) detailed description of experimental research examining the cyclic behaviour of chimney sections and (c) development of an aseismic design and analysis procedure for reinforced concrete chimneys including code recommendations.
