Seismic Analysis of Substation Facilities Considering Interaction Effect

765kV substation facilities are most important as electric power supply network in the 21 century. So, in order to prevent interruption of electric power supply under earthquake, 765kV substation facilities have to secure the safety against the earthquake. However, even though each substation facility is interconnected mutually, seismic interaction effect doesn't be considered in the initial design. Therefore, seismic capacity evaluation of 765kV substation facilities is carried out considering the seismic interaction effect on a basis of seismic design criteria for Korean transmission and substation facilities.
