In areas of low to moderate seismicity, displacement controlled behaviour is a phenomenon in which the displacement demand on the structure would not increase indefinitely with increasing structural period. Deficiencies that are inherent in the conventional force-based seismic design method could result in undesirable and illogical consequences for long period structures in particular. This paper is concerned with the adaptation of the displacement based seismic design methodology to cable stayed bridges which are characterised by high horizontal flexibility and low natural frequencies. The model that has been developed using program Opensees can be used for investigating the dynamic characteristics of structures with a cable-pylon system.
