The test is conducted in as-installed configuration that includes a support structure and the electrical equipment mounted on top of the latter. According to the requirement, the equipment has to be re-tested every time a new support structure is introduced. The support structure’s design for the same equipment varies from utility to utility and is related to the utility’sspecific needs, design practice, and constraints. Therefore, every time a utility company requires a new support structure, a complete assembly of the new support structure and its equipment, needs to be re-tested in a shaking table test which is time consuming and expensive. The main objective of this paper is to study numerically such coupled systems consisting of a support structure and high-voltage substation equipment to provide recommendations on the design of the support structures. Optimization of the support structure design that results in adequate seismic performance of the equipment is studied in this paper. The results of the analysis are verified by full-scale tests of a 500-kV air disconnect switch on the shaking table. The complete assembly of the full-scale switch including the support structure is more than 10 m tall and the equipment is about 5 m tall. The same piece of equipment is seismically tested on different support structures to estimate the effect of the support structure on the overall performance of the coupled system. Moreover, the results of this experimental and analytical research are compared to real-time hybrid simulation results of similar equipment published earlier.
